  On the morning of July 16th, people held a short and solemn farewell ceremony for Liu Anjun, a reserve soldier of 3rd Battalion, 3rd Regiment of Anhui Army Reserve Infantry Division, who died heroically in the flood fighting. The CPC, county and county committees ratified Liu Anjun as "excellent communist party member". During the most difficult period of flood fighting and rescue, Liu Anjun fought in the front line for 11 consecutive days. On July 13th, he died of sudden cardiac death due to fatigue.

  Go to the rescue overnight

  Liu Anjun, born in 1983, joined the army in 2003 and retired in December 2015. In April this year, he was incorporated into the 2nd platoon and 4th class of the 3rd Battalion Artillery Company of the 3rd Regiment of the Anhui Army Reserve Infantry Division and became a reserve soldier.

  Since the end of June, Chaohu Lake Basin has suffered from continuous heavy rainfall. On July 1, the dike of Xiaozhu Village in Xiage Town, Chaohu City was in danger of collapse. Liu Anjun, who was participating in reserve training, was incorporated into a flood fighting and rescue commando team composed of 65 pre-appointed officers and men. At 11: 55 that night, the commando rushed to Xiage Town to rescue the dangerous embankment in the rain.

  Ren Juntao, deputy director of the armed forces department of Xiqiao Town, recalled, "It was raining cats and dogs that night. Because the embankment was narrow and the road near the dam was blocked, the vehicles carrying materials could not get in. The officers and men had to unload the flood-fighting materials from the vehicles and carry them to the dam urgently."

  At first, Liu Anjun carried the woven bag with three other soldiers. Without taking two steps, Liu Anjun said, "It’s hard for several people to carry it, or I will carry it alone." So he picked up a bundle of woven bags weighing more than 100 kilograms and ran forward. Along the way, the mud was slippery and easy to sink, and he was soaked all over, and he struggled forward with the weak light of a flashlight … … That night, Liu Anjun’s commando team worked until 4: 50 the next day, transporting more than 46 cubic meters of sand and stones, strengthening the dam and blocking the piping. Taking off his clothes, Liu Anjun’s shoulders grinded out blood stains. "Every time he always carries a little more than others and runs a few more times, but he never complains that he is tired." Liu Anjun’s teammate Li Zongbin recalled carrying a bag with him.

  At 11: 00 on July 5, the commando team received the task of repairing the collapse of two embankments in Hedong Wei, Gongqiao Town, Hexian County. Liu Anjun reinforced the dam with his teammates, and after finishing his 30-meter embankment reinforcement task with sandbags, he helped his teammates to transport sandbags until 8 pm. At 12 o’clock on July 6, the water level in Xibakou, Chaohu City rose and the dam was in a hurry. The commando team rushed to the dangerous section of the dike for 20 kilometers, and worked for nearly 10 hours. For seven days in a row, Liu Anjun and his comrades-in-arms moved to the dikes of three towns and villages overnight, and worked all the way at night, eliminating five dangerous places, carrying more than 550 cubic meters of earth and stone, building more than 350 meters of dikes and repairing more than 200 meters of collapsed dikes.

  On the 7th, the danger in Chaohu Lake Basin was brought under control, and the commandos withdrew to the camp to rest. Liu Anjun was awarded the title of "advanced individual in flood fighting and emergency rescue" by the third regiment of the reserve infantry division of the provincial military region. "Liu Anjun can bear hardships and has a very strong fighting capacity!" Ren Juntao evaluation.

  Go home to visit relatives and take the initiative to patrol the embankment.

  Liu Anjun was born in an ordinary peasant family in Shengjiakou Village, Xibu Town, Ma ‘anshan City. After 12 years as a soldier, he devoted himself to the army and went home to visit relatives less than 10 times.

  On July 8, Liu Anjun, who returned home, found the village party branch secretary to take the initiative to participate in the rescue when he learned that his hometown Wangjiawei dike was in danger of flooding for 100 meters. When the village decided to select 15 of the 122 party member in the village to form the party member Emergency Commando, he was the first to sign up. At 13: 00 that day, Liu Anjun, who had not rested for half an hour, fought with the villagers and commandos to reinforce the dam. Until 17: 00, he built a 100-meter-long and half-meter-high flood control sub-dam, which ensured the safety of the villagers in Shengjiakou Village. After completing the assault rescue mission, Liu Anjun volunteered to take part in the village’s work of strengthening, cleaning up impurities and inspecting the dikes of the 8.9-kilometer-long bank of Desheng River. During the day, he patrolled the 2-kilometer levee and patrolled the 8.9-kilometer levee in shifts at night. Liu Anjun always went to the levee in advance every day. When the situation is urgent, Liu Anjun, like other people patrolling the embankment, never leaves the embankment and eats "a hundred meals" on the levee.

  On the 12th, Liu Anjun began to check the risks as usual. He is responsible for delivering water to more than 80 migrant workers who mow grass, with a barrel of water of more than 30 kilograms. One person has carried 5 barrels of water successively, and walked for nearly 20 kilometers. The temperature of the day was as high as 35 degrees Celsius, and he waited until all the people involved in cleaning up the debris left the embankment. At noon, Liu Anjun felt unwell, and his uncle Qi Yefu advised him to go home and rest. He shook his head and said, "Nothing, I’ll check this embankment before I go back." At 11 o’clock in the evening, Liu Anjun dragged his tired body home, neglected to take a bath, and fell asleep on the sofa for fear of affecting his sleeping family. In the early morning of the 13th, when 120 emergency doctors arrived at Liu Anjun’s home, Liu Anjun’s heart had stopped beating at the age of 33.

  "He’s always at the forefront."

  "Every day after An Jun comes home from the levee, I wash and fold his dirty camouflage uniform and put it on the windowsill for him to change it. I never thought that my son would never wear my washed camouflage uniform again … …” Liu Anjun’s mother, Zhao Xianyu, was in tears.

  When his lover passed away, his wife Zhang Feng was heartbroken. "Every night when An Jun comes back, I will adjust the bath water and squeeze his toothpaste in the morning. Now, I can’t wait for An Jun to come back. "

  In the days of flood fighting and emergency rescue, Liu Anjun and his wife exchanged thoughts and reported each other’s safety by mobile phone.

  "This is his blood donation card." Zhang Feng took out a little red book from his bag, which recorded the time and blood volume of her husband Liu Anjun’s blood donation every time. Since 2004, Liu Anjun has donated 2,500 ml of blood. "He is a party member, and he is good."

  "He always maintains the style of a soldier, always rushing to the forefront, and wherever there is something, he will go!" Wang Xiaobo, a former colleague of Liu Anjun and a cadre of Xiqiao Town, recalled that on the New Year’s Eve last year, Liu Anjun stayed in the town as a member of the town militia emergency detachment. When he learned that a forest fire broke out at the foot of Dagushan Mountain on Shengshan Road, he and more than 30 members of the town militia emergency detachment rushed to the scene to put out the fire.

  "He rushed to the front." Wang Xiaobo introduced that at that time, there were many thorns on the mountain, and Liu Anjun leaned down with a fire extinguisher to put out the fire. "The fire broke out everywhere, and his camouflage suit was broken by the burning trees, Mars and thorns in generate. His clothes, face and nostrils were full of soot, and the rubber shoes under his feet gave off bursts of burnt smell. He completely ignored it and fought for four hours before ending the battle."

  "Liu Anjun is the pride of the soldiers. His 12-year military career and tempering have been deeply integrated into his blood. His fighting spirit is worth learning from all officers and men. " Dai Yong, political commissar of Anhui Military Region, said. Our reporter Zhu Sixiong Ye Qi

Key technology "stuck neck" How should the domestic bicycle industry find another way?

  In 2022, the total output of bicycles in China exceeded 51 million, and these bicycles can circle the earth more than 2 times end to end. Once a "bicycle kingdom", it is still a bicycle country. But who would have thought that the bicycle industry in China, which is world-renowned, still faces the dilemma that key parts are "stuck" in some high-end varieties.

  Behind the above phenomenon, it reflects the common problems encountered in the transformation and upgrading of traditional manufacturing industries, including the bicycle industry.

  The General Secretary of the Supreme Leader pointed out that to promote the transformation and upgrading of China’s manufacturing industry and build a manufacturing power, we must strengthen technology research and development, improve the localization substitution rate, and take the lifeline of science and technology into our own hands, so that the country can truly become strong.

  At present, the key technology "stuck neck" and the brand "more but not stronger" are puzzling most domestic bicycle enterprises, and the high-quality development of bicycle industry is still difficult. On the new journey of building a manufacturing power, how should bicycle enterprises find another way, constantly shape their own brands and advantages, and form the competitiveness and influence of China bicycle enterprises in the global market? All these require enterprises to give answers in innovation and change.

  Supply:

  Why are high-end models in short supply?

  "It was really ‘ A car is hard to find ’ The customer wants to buy, but the goods can’t get in. " Bai Xuekui, the manager of Merida Public Welfare Bridge Store in Fengtai District, Beijing, still remembers the situation in the second half of 2022. "This situation was very common in the Beijing bicycle market at that time."

  The Tianjin market has also felt changes. Li Qiuju, assistant to the president of Golden Wheel Group and manager of Hundred Guest Houses, said: "Last year, road bicycles suddenly burst into flames, and many riders were looking for them everywhere. This year, in the Bike Life Experience Hall of Baikeyu, the average sales volume of folding bikes and mountain bikes also increased by about 10% compared with previous years. "

  Is the shortage of supply a local phenomenon or an overall situation, or is it the hype of bicycle dealers?

  Guo Wenyu, vice chairman and secretary general of China Bicycle Association, told reporters that in the second half of 2022, especially in the fourth quarter, the phenomenon of "one car is hard to find" for high-end bicycles in first-tier cities including Beijing is more prominent, but not in second-and third-tier cities. According to incomplete statistics, since 2022, the domestic sales of high-end sports bicycles have increased by more than 30%.

  The dealer’s feelings were passed on to the whole vehicle enterprise. Jinghai District of Tianjin is known as the "Bicycle and Electric Bicycle Capital of China", and the market share of brand bicycles in the area reaches 25%. During the interview here, from time to time, you will see a van full of bicycle parts whizzing by.

  "Last year, the supply of mid-to high-end models was in short supply." Guo Fangcheng, general manager of Giant (Tianjin) Co., Ltd. introduced that Giant Tianjin Company has an annual output of about 1.2 million bicycles, and 85% of its products are sold domestically, and most of them belong to mid-to high-end models. "At that time, corporate inventory was empty, and high-end cars, road cars and some online celebrity cars were even more sought after. This year, the situation has eased."

  Guo Wenyu believes: "Affected by the epidemic, individuals are more willing to travel by bike. Coupled with the rise of leisure and fitness concepts, the market demand for bicycles has increased significantly. In addition, in the second half of 2022, due to the closure of the epidemic, the production capacity of some parts manufacturing enterprises was less than expected, resulting in a decline in vehicle output. "

  "Appear ‘ A car is hard to find ’ The main reason is the lack of high-end parts, especially the lack of high-end bicycle transmissions. In addition to waiting for a long delivery period, domestic enterprises can only stock up in advance or seek domestic substitution. " Zhang Xudong, vice president of Tianjin Kelin Vehicle Industry Co., Ltd. said.

  How tight is the high-end transmission? Lin Jing, assistant to the chairman of Shenzhen Xidesheng Bicycle Co., Ltd., gave an example. At that time, a brand of high-end transmission often had to increase the price to buy it. In order to get the goods, local dealers often risk default and place the same order with three vehicle manufacturers. "As long as you get the goods, even if you pay 20% of the liquidated damages, it is better than nothing to sell." Lin Biao said.

  High-end transmissions are so scarce, why don’t manufacturers increase production capacity? This can’t help but mention Shimano.

  According to reports, Shimano is a multinational group company specializing in manufacturing and selling bicycle parts, fishing gear, snowboarding and golf supplies, headquartered in Japan. According to the data, two brands, Shimano in Japan and Speedlink in the United States, occupy the vast majority of the global bicycle transmission market, and Shimano’s shipments account for more than 60% of the global market.

  According to another data, the annual demand for bicycle transmissions with a price above 1,000 yuan in China is about 8 million sets, and 95% of the market share is in the joint efforts of Shimano and Speed, among which Shimano accounts for the bulk. This means that Shimano’s every move on the transmission will have an impact on the middle and high-end bicycle market.

  In 2022, due to the closure of the epidemic, some parts factories of Shimano in Southeast Asia and other places stopped production, and the delivery date of transmission parts was uncertain, resulting in insufficient production capacity.

  The increase in demand meets the shortage of supply, which intensifies the shortage of high-end transmissions.

  The reporter interviewed the bicycle department of Shimano (Shanghai) Trading Co., Ltd. Staff said that since the outbreak of the COVID-19 epidemic in 2020, the global demand for bicycles has soared, and all brands have set positive sales targets. Shimano has also received orders far exceeding its own production capacity. Despite the efforts of the company’s factories to increase production capacity, it still cannot meet the rapidly increasing market demand.

  Will the situation of "one car is hard to find" continue? Some companies are optimistic about the market outlook.

  Lin Jing predicts that mid-to high-end cars will still sell well. The person in charge of a vehicle enterprise said that from the perspective of spare parts supply, the supply of low-end cars is sufficient, and the delivery period of high-end bicycles is relatively long because of their small demand.

  The staff of the bicycle department of Shimano (Shanghai) Trading Co., Ltd. said: "At present, the delivery time of most products of the company has been greatly improved, especially the delivery time of entry-level products has basically returned to normal. According to the current market situation, the company will face the pressure of overcapacity, so the production plan will be adjusted accordingly according to the actual market demand." Accordingly, some dealers have judged that the shortage of mid-to high-end models has been alleviated.

  At present, the bicycle inventory of big brands is still at a high level, and the overall inventory is mainly digested. Xu Weiyao, deputy general manager of the business department of Shenzhen Xinlong Health Industry Development Co., Ltd., believes that in the case of downward market demand, low-end commuter cars will not only be hard to find, but also be surplus and even have a price war.

  Experts in the industry said that "one car is hard to find" for high-end bicycles, which fundamentally reflects the problem of insufficient supply of high quality and is the embodiment of structural contradictions in the bicycle industry. If China wants to grow from a big bicycle country to a powerful bicycle country, it needs to further improve its product structure, make efforts to lay out the mid-to high-end market and make up for the short board of "transmission".

  R&D:

  How to break through the bottleneck of transmission

  To solve the problem of insufficient quality supply in bicycle industry, we must find a way in technology research and development. For bicycles, the most difficult thing to develop is the transmission.

  China has the manufacturing industry with the most complete industrial categories and the most complete industrial system in the world. So many major technological bottlenecks can be broken. Why is it difficult to independently develop a small bicycle transmission?

  When the reporter met Liu Chunsheng, the founder of Zhuhai Blueprint Controller Technology Co., Ltd., he was communicating with foreign customers about the transmission experience. This "post-70 s" man is less than 50 years old and his hair is gray. He joked that he had made a fool of himself for the domestic transmission.

  He’s not the only one who’s survived. Liu Weibing, the general manager of Suruida Bicycle Parts (Foshan) Co., Ltd., is about the same age as Liu Chunsheng, and also has white hair.

  Both of them are from American Speedlink Company, and they also joined the field of transmission manufacturing after American Speedlink withdrew from the mainland of China. Years of immersion have given them a deeper understanding of transmission development.

  Transmission is not only a single component, but also a complex system, and now it has almost become a standard for bicycles. In order to complete the speed change of bicycle, more than 100 parts including tooth plate, flywheel, front shift and rear shift need to be coordinated.

  To put it bluntly, many domestic manufacturing enterprises can produce this set of parts, and the technical content is not high. To make it easy, these enterprises can only produce low-end products, and there are very few high-end products that have been mass-produced

  Liu Chunsheng introduced that Japanese Shimano has a history of 100 years, and American Speedlink has been established for more than 30 years. Domestic transmission enterprises have not started for a long time and have not accumulated enough. However, the gap not only exists in the insurmountable time accumulation and the number of products, but also is subject to patent technical barriers.

  It is understood that Shimano has applied for more than 6,000 patents in the world, and more than 2,500 patents in China. "A simple transmission has such a huge patent layout that it basically locks the way for latecomers." Liu Weibing, an engineer, said with emotion that the variable speed technology is not difficult. What is difficult is how to circumvent patent restrictions and avoid falling into patent disputes with international brands.

  "How difficult is it to bypass patent restrictions? For example, the transmission will sleep when the bicycle is at rest, and the car will move and need to be woken up. Shimano applied for the patent of transmission vibration sensor in China. In order to avoid infringement, Blueprint Technology has developed an angle sensor and an acceleration sensor for wake-up operation. But because the vibration sensor technology has been perfected after dozens of iterations. However, our technology application time is short, and there are still many bugs that need to be fixed, which is worse in stability. " Liu Chunsheng said.

  "Our thinking is, on the one hand, to steadily promote the development of mechanical transmission, on the other hand, to open up new technical routes by changing lanes." Liu Chunsheng said that it is difficult for domestic enterprises to shake Shimano’s dominant position in mechanical speed change, but in electronic speed change, relying on China’s solid electronic information industry foundation, we are confident to solve the problem of "sticking the neck".

  In March of this year, Blueprint Technology launched the first highway transmission kit integrating hydraulic disc brake and electronic transmission in China — — Blueprint eRX road vehicle electronic transmission kit, vigorously layout the electronic transmission market. At the 31st China International Bicycle Exhibition held recently, Lanxi Lunfeng Car Material Co., Ltd. also brought its own electronic transmission kit for road vehicles.

  In addition to patents, precision machining capabilities also need to be improved. The relevant person in charge of the Guangdong Bicycle Association said that high-end transmissions require even higher manufacturing accuracy than watches. "Unlike mechanical watches, which are in a stable state most of the time, bicycle transmissions are in high-speed motion for a long time, and the accuracy of parts is very high. The processing accuracy of some parts should reach one tenth or even one percent of the diameter of hair."

  For processing enterprises, such accuracy is not difficult to achieve, the difficulty lies in how to balance the relationship between cost and quality. The products provided by big suppliers can meet the accuracy requirements, but they are unwilling to do it because of the small order volume. Small suppliers are willing to do it, but the machining accuracy is unstable.

  How to solve the processing problem? Surida chooses to use the products of foreign big brand suppliers, but it has to bear higher prices. Blueprint Technology also adopted the form of outsourcing before, but with the scale expansion, it began to consider cultivating its own suppliers, or even building its own supply chain, but it took longer and more investment.

  In addition to patent barriers and processing accuracy, materials are also a problem. A person in charge of a domestic transmission manufacturer told reporters that the transmission requires high hardness and toughness of materials. However, at present, the domestic steel products are brittle with strong rigidity, and the hardness with strong toughness is not enough, so the overall performance can not reach the quality of similar products abroad.

  According to experts, the annual demand for steel in the domestic bicycle industry is about 3 million tons, and the consumption of transmission steel is even less. This demand is far from being a big customer for iron and steel enterprises. If we cooperate in the research and development of special steel for transmission, the research and development cost is a problem, and whether the order quantity can meet the mass production standard after research and development is another problem.

  Liu Weibing believes that from the R&D point of view, the high-quality development of bicycle industry needs the cooperation of technology, technology and materials. At the same time, this test is how to balance the relationship between short-term interests and long-term strategy.

  In the interview, the reporter found that some cyclists pay more attention to parts brands than vehicle brands. For example, the price difference of the same giant vehicle can even be several thousand yuan if different brands of transmissions are used. This is the brand premium.

  Qian Heng, the head of Beijing Kangaroo Bicycle Club and a senior cyclist, said, "The foreign high-end transmission is not only of good quality, strong stability, accurate speed change and continuous speed change without trip stop, but also looks like a connotative handicraft. It is very recognized inside and outside the circle. "

  "In recent years, domestic transmission companies have made great progress, and some products have gradually established a reputation, but they still need to improve their quality and cultivate consumers’ habits." For Qian Heng, it will take time for high-end domestic transmissions to be widely used by vehicle manufacturers and widely accepted by consumers.

  There are many difficulties and great difficulties, but it does not mean that it is difficult for domestic transmission enterprises to have a bright future. "One car is hard to find" brings an excellent window period. Because of the shortage of foreign brand transmissions last year, domestic automakers began to partially use domestic high-end transmissions on mid-to high-end models.

  With the help of Dongfeng, domestic transmission enterprises quickly make up the position in output. Blueprint Technology will achieve an average annual operating income of over 100 million yuan in 2020 and close to 200 million yuan in 2021. In 2019, Surida’s annual revenue was only a few million yuan, and it doubled in 2020 and 2021, and its revenue in 2022 exceeded 30 million yuan.

  In June, 2022, the Ministry of Industry and Information Technology, the Ministry of Human Resources and Social Security and other five departments jointly issued the Guiding Opinions on Promoting the High-quality Development of Light Industry, officially including bicycle transmissions in key technology research and development projects. The research and manufacture of bicycle transmission will have more new expectations.

  Operation:

  Don’t be misled by the wrong market signal.

  The shortcomings in research and development have not affected the total output of bicycles. However, the constant switching of enterprise’s operation strategy and the invariability of product strategy bring a lot of disturbance to the transformation and upgrading of the industry.

  A few years ago, the bike-sharing agitation disrupted the pace of industry development, delayed the pace of industrial transformation and upgrading, and delayed the problem of "hard to find a car" so far.

  How big is the impact of bike-sharing agitation on the industry? "At that time, bike-sharing’s big orders stunned many companies." Zhang Xudong said that as soon as the orders for millions of vehicles came, many enterprises tried their best to expand their production capacity, and Colin went to six new production lines at that time. As an export-oriented enterprise, the company’s production capacity in bike-sharing at that time was once higher than that in export.

  The technical director and reporter of Shenzhen Xinlong Health Industry Development Co., Ltd. told another story: At that time, the welder who welded the frame in the factory hurried out as soon as he got off work, and he was still very tired every day. Quietly inquired, I realized that this welder took a job outside, which is to work hard for small enterprises to make bike-sharing.

  During the bike-sharing boom from 2016 to 2018, all enterprises, workers and capital were stimulated by the boom and gradually lost their minds. Large and small enterprises have adjusted their original strategic layout and added bike-sharing.

  Success is shared, and failure is shared. Many business people believe that the impact of bike-sharing agitation on bicycle enterprises is comprehensive, which not only disrupts the production rhythm of enterprises, but also increases the production cost. Xu Weiyao said that at that time, the demand for aluminum alloy in the domestic bicycle industry was 2 million tons per year, and the order from bike-sharing directly raised the demand to more than 5 million tons. The surge in demand also raised the price of aluminum alloy in disguise. This requires enterprises to "pay the bill".

  Bike-sharing agitation is like a mirror, which shows the cruelty of the market and the most real ability of enterprises.

  However, it is also bike-sharing, which makes the concept of cycling more deeply rooted in people’s hearts, and also increases the stable source of orders for the industry.

  At present, the market structure in bike-sharing is initially determined, and three bike-sharing brands, namely Meituan, Harrow and Qingju, are more rational in product delivery. The annual output of bike-sharing has remained at around 5 million vehicles, which has been greatly reduced compared with the peak of 20 million vehicles in 2017, but it has provided a strong guarantee for the industry to ride out the crisis smoothly.

  After the impact of bike-sharing, the industry once again experienced a "roller coaster" market.

  In 2020, with the outbreak of COVID-19 epidemic, "cycling fever" spread all over the world. The increase in cycling demand has led to a sharp increase in bicycle production and sales. The national bicycle production has rapidly increased from 65 million in 2019 to 75.275 million in 2020. Among them, the number of bicycles exported in 2020 was 60.297 million, a year-on-year increase of 14.8%. In 2021, the total output reached 76.39 million vehicles, reaching a new high. However, with the relief of the epidemic and the saturation of demand, the output fell rapidly again, and the contradiction gradually exposed.

  According to the data of China Bicycle Association, from January to March this year, 8.711 million bicycles were exported, down 33.4% year-on-year; The export value was US$ 828 million, a year-on-year decrease of 21.4%. In fact, since the second half of 2021, the growth rate of bicycle exports has begun to drop significantly.

  There are two main reasons for the decline of export market. Wu Jincheng, president of Fujitec Group, told reporters that one is that overseas markets are generally facing high inflationary pressures and consumers’ purchasing power is declining. The other is high inventory. Since the outbreak of the epidemic, overseas dealers have hoarded a large number of bicycles and spare parts in response to the surge in demand and the inconvenience of shipping, resulting in excessive inventory. High inventory and low demand directly lead to a decline in exports.

  Faced with the huge overseas market demand in the early stage, many bicycle companies quickly turned their bows, adjusted their strategies and expanded their production capacity. But when external demand drops, it is not so easy to shrink production capacity.

  With weak export, will enterprises shift their sales focus to China? As a typical export-oriented industry, how can the bicycle industry adapt to the new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other?

  Guo Wenyu believes that under the new development pattern, bicycle enterprises should strive to explore the domestic market, while consolidating the demand of bike-sharing, constantly meet the demand of consumption upgrading, enhance the added value of products, increase the share of independent brands, and let more China brands return to consumers.

  Ai Media Consulting analysts believe that the bike-sharing turmoil and the decline in exports have brought two inspirations to the bicycle industry: First, enterprises should have long-term operating strategies, adhere to stable development and steady operation, and not be biased by wrong market signals; Second, enterprises can not be satisfied with OEM, but should strive to develop their own brands and increase the added value of products, so as to gain a firm foothold in the market.

  Small profits but quick turnover are the advantages and strategies of the bicycle industry for many years. However, in the case that the sales volume has not changed much, any trouble in raw materials, labor and freight will have a great impact on the enterprise. In the past two years, bicycle companies have been hit by rising costs.

  Zhang Xiaoping, general manager of Guangzhou Trinidad Sales, said that in 2021, foreign trade enterprises, including bicycle enterprises, will face the problem of "one box is hard to find". In the face of difficulties, bicycle companies try to deal with them. In order to save costs, Tianjin Kelin Vehicle Co., Ltd. adopts the mode of transshipment and merger, tries to avoid direct arrival in Hong Kong, and at the same time reduces transportation costs by merging with other goods. Some enterprises with strong bargaining power will also negotiate with customers and ask them to share the pressure of rising freight rates.

  As raw materials for bicycle frames, the prices of aluminum alloys and magnesium alloys have increased greatly. According to estimates, when the price of aluminum is at the highest point, the manufacturing cost of a bicycle rises in 20 yuan. For enterprises that focus on low-end models, they can only continue to compress profits and bear the pressure of rising costs. However, for enterprises with a relatively high proportion of mid-to high-end models, the impact of price increases can be digested by increasing the price of products.

  In mid-2022, the China Bicycle Association released a report saying that by the end of 2021, the ex-factory price of upstream raw materials had increased by more than 15% year-on-year. In April 2022, the ex-factory price of durable consumer goods, including bicycles and electric bicycles, decreased by 0.1% year-on-year, and enterprises assumed most of the cost pressure, and the profit margin was further compressed.

  This year, the price of bicycle raw materials has declined, and the cost of shipping has dropped greatly. However, the bicycle industry is facing new problems: the comprehensive cost continues to rise; Some small and medium-sized enterprises shut down, and the foundation of industrial recovery is not firm; Domestic and international consumer demand is insufficient, and export orders have not fully recovered.

  According to this expert, for heavy asset enterprises such as bicycle enterprises, in order to transform and innovate to improve quality, it is necessary to change the operation mode and develop towards high added value such as high-end and branding.

  The relevant person in charge of the China Bicycle Association believes that we should look at some problems encountered in the current industry from a macro perspective. The long-term positive trend of China’s economy has not changed, nor has the international competitive advantage and development resilience formed by the industry. Enterprises should maintain strategic strength, continue to tap the potential of the domestic market, expand domestic demand and protect exports, continue to consolidate the recovery trend of operation, and ensure steady and progressive operation throughout the year.

  Input:

  Where does the innovative capital come from?

  The innovation and development of bicycle industry, whether it is to increase research and development, expand production capacity, adjust product structure or carry out brand promotion, can not be separated from financial assistance. But an embarrassing reality is that there is no money.

  Judging from its own situation, the profitability of the domestic bicycle industry is weak and the capital investment is generally insufficient. "The most expensive component of bicycles is the transmission, which can account for 40% of the cost of the whole vehicle, but most of this profit is earned by foreign companies, and domestic companies are more concentrated in low-profit links such as frame and paint." Zhang Xudong said.

  Yang Yufeng, general manager of Jinlun Group, believes that the competition in the domestic bicycle industry is fierce, and the profit rate of individual enterprises is even less than 3%. With such a low profit margin, enterprises mainly rely on scale to win.

  It has been reported that from the perspective of product positioning, the products of China’s bicycle enterprises are mainly low-end products, with low technical content and low added value, resulting in low profit margin. In recent years, the total profit of China’s bicycle manufacturing industry has steadily increased, but the profit rate level fluctuates.

  According to the data of China Bicycle Association, in 2022, the operating income of enterprises above designated size of bicycles and electric bicycles was 210 billion yuan, a year-on-year increase of 3%; Profits exceeded 10 billion yuan, up more than 20% year-on-year. Among them, the profit margin of bicycle industry increased to 5.4%. In the first quarter of 2023, the profit rate of bicycle industry revenue was 3.3%.

  Low profit means that there will be no high return, and it is difficult to attract funds.

  "Capital is profit-seeking. Low profits are hard to attract the attention of capital. Enterprises can only change their business ideas and produce mid-to high-end models with higher profit margins, and it is possible to increase the profit margin to more than 10%, but the transformation will face great market risks. " Yang Yufeng said.

  In fact, the current capital has invested in the bicycle industry, but it is mainly concentrated in two areas: one is competitive sports, and the other is electrification and intelligence.

  Zhang Xudong said that capital investment in head enterprises that do well in competitive sports does not value their manufacturing level, but that competitive events can bring huge profits. For example, the capital is interested in the Tour de France team because of its high attention and great influence, which plays an obvious role in driving the brand.

  Apart from low profits, capital is not familiar with the bicycle industry. Yang Yufeng said that a lot of capital didn’t go to the market to do research, didn’t understand the sales situation of domestic bicycle enterprises in the market, especially in foreign markets, lacked understanding of products and were not sure about the development prospects of enterprises.

  "This also reminds us that to find reasons from ourselves, traditional bicycle companies should frequently interact with capital." Guo Wenyu said that we welcome capital to enter, and hope that more attention and support from social capital can also help the industry to grow and develop. To this end, the China Bicycle Association has taken active actions and organized many activities to connect key enterprises in the industry with venture capital.

  Capital is "not cold" to bicycle companies, and another important reason is that companies can’t tell stories. Yang Yufeng said that in order to attract capital to join, it is necessary to tell your own story well and let capital see the future of the enterprise. In contrast, some bicycle companies enthusiastically embrace electrification and intelligence, and put forward many new concepts, which are quite concerned by the market.

  Xu Weiyao did not use "telling stories", but replaced it with the word "vision". "An important factor for bicycle companies to attract capital is to have a vision, and the vision should conform to the future industrial development trend. I only know how to expand the scale and increase production. Without a vision, it is difficult to win favor. "

  What is a vision? In the lobby of Shenzhen Xinlong Health Industry Development Co., Ltd., from bicycle parts to scooters and ordinary bicycles to wheelchairs, all products are lined up in turn, and the product line covers the whole life cycle of people. "The vision of Xinlong is great health." Xu Weizhen introduced that in 2016, Xinlong changed its company name from Xinlong Industry to Xinlong Health.

  Zhang Xiaoping believes that domestic bicycle enterprises are generally small in size, and it is the big enterprises that achieve an output value of several billion yuan. At the same time, the domestic industry structure is relatively fixed, the head enterprises are developing well, and it is difficult for the latter enterprises to catch up, and it is even more difficult to have a chance to break the game. This is also a reason why capital is unwilling to invest.

  "Since it was founded in 2013, we have been trying to find a way ‘ Make money ’ 。” Liu Chunsheng said that only money can solve the most critical R&D problems of enterprises. He admits that domestic bicycle companies only have a profit margin of 3% to 7%, which is difficult to support high R&D expenditure. Only venture capital can alleviate this pressure. For Blueprint Technology, it is the joint investment of Shenzhen Venture Capital and Gaoyao Capital that has solved the urgent need.

  Xidesheng’s attitude towards capital is relatively calm. Lin Jing said that although the company’s listing plan is progressing, it is still based on safety. At present, Internet companies are expanding rapidly by the east wind of capital, which brings both opportunities and challenges. "The thinking of enterprises that started from the manufacturing industry is different from that of Internet enterprises. It is still necessary to do business one step at a time."

  The entry of capital is not just about money. Taking Xinlong Health as an example, Xu Weiyao said that listing not only brings sufficient funds to enterprises, but also helps enterprises to improve corporate governance, consolidate basic management and achieve standardized development. Modern corporate governance structure is more likely to be recognized by overseas customers and also helps to enhance brand image.

  In fact, there are many listed companies in the industry. Bicycle companies include Zhonglu, Shanghai Phoenix and Xinlong Health, and electric bicycle companies include Yadea Holdings, Xinri, Emma Technology, No.9 Company and Mavericks Electric. These listed companies not only lead the development of the industry in scale, but also lead the industry in standardization.

  Affected by this, some bicycle leading enterprises that have not yet been listed have begun to arrange listing financing.

  Wu Jincheng introduced that in June 2022, Fujita launched a listing plan to land in the capital market. According to the previous process, enterprises need to go through the project filing and EIA review of new projects before they can submit the prospectus to the Shanghai Stock Exchange and strive to submit materials this year.

  Zhang Xiaoping said that Trinidad has been selected into the list of 100 companies to be listed in Guangzhou, and the listing plan is in progress. Yang Yufeng revealed to reporters that Jinlun Group is also making preparatory work and striving to complete the listing within three years.

  Upgrade:

  Brand building and industrial ecology

  There is a view that the bicycle industry is very important, but in comparison, the output value is not very large, the profit is not high, and it is not a big country, and it basically does not involve national security. Some key parts can’t be developed by enterprises, so just spend money to buy them. Even if foreign enterprises don’t sell them, it won’t have much impact. Why do you have to master all the technologies in your own hands?

  In this regard, Guo Wenyu answered firmly and decisively. "Bicycle companies do research and development and break through ‘ Get stuck in the neck ’ Technology is to get rid of control, realize self-reliance in science and technology, and improve the industry’s right to speak in the global industrial chain. If you have been wandering in the low end, there is no technological breakthrough. Once the advantage is lost and the industrial chain shifts outward, enterprises will face the test of life and death. As a national industry and a national brand, such a result is unacceptable. "

  "There is another important reason. Enterprises carry out scientific and technological innovation and overcome technical difficulties in order to benchmark the advanced, learn from the development experience of foreign enterprises and strengthen themselves. If an enterprise has no goals and pursuits, but just earns immediate money, how can it get rid of the quagmire of low-end competition and how can it maintain its long-term success? " Guo Wenyu said.

  The high-quality development of bicycle industry needs to promote technological innovation, but it is difficult to have subversive changes when the bicycle structure has not changed much, and more innovations are subtle.

  Xu Weiyao said: "In the eyes of outsiders, bicycle research and development is only a change of some angles and parameters, and there is no new creation, but it is these nuances that are the essence of the industry. Bicycle companies can only build a good car if they know more about it. "

  Xu Weiyao gave an example: "Chip manufacturing is very difficult, but it is more difficult to control the defective rate. Controlling the non-performing rate controls the cost and consolidates the advantages. Similarly, for bicycle companies, process control and quality management are sometimes more important than technological innovation. "

  The main product of Ningbo Henglong Vehicle Industry Co., Ltd. is a small front bowl on a bicycle, with an annual output of nearly 50 million sets. On such a large scale, the product size error is only about 0.03 mm. Hu Ruke, the person in charge of the company, believes that the key to achieving good consistency and stability lies in process control.

  Wang Chaoyang, president of Shanghai Phoenix Bicycle Co., Ltd. said that in the process of breaking through to the high end, the industry needs to calm down, abandon low-price competition, strengthen support and mutual assistance within the industry, do a good job in research and development of important parts, and further improve the high-quality development level of the bicycle industry.

  Facing the trend of intelligentization and electrification, the White Paper on Intelligent Development of Bicycles and Electric Bicycles in China (2022 Edition) points out that the industry is characterized by the backward shift of the industrial value chain, the increase of the total amount, the gradual acceleration of the application of information technology, the steady progress of intelligent production upgrading and the gradual obvious trend of platform management, and the continuous intelligent upgrading has become an inevitable road for the transformation of vehicle enterprises.

  According to industry experts, at present, the intelligent development of bicycle enterprises mainly has two aspects, on the one hand, hardware intelligence and software intelligence. Bicycle companies have joined the Internet of Things application through technical cooperation with companies such as Ali and Huawei, providing more choices for cyclists.

  On the other hand, it is the construction of intelligent platform. In the investigation, the reporter found that the automation rate of domestic bicycle enterprises is not very high as a whole. Intelligent manufacturing is more used in welding, painting, stamping and other links. For the sake of production cost, small batch and multi-variety processes are mainly manual.

  How can bicycle enterprises develop with high quality? The common answer is: technological innovation, transformation and upgrading. There is another point that cannot be ignored: building a brand.

  Zhang Xudong believes that efforts should be made to cultivate private brands, and brand promotion and operation should be done well on the basis of consolidating product quality and after-sales service. Although some vehicle companies have their own brands, they have not been carefully managed and planned.

  Yang Yufeng also agrees with the role of brands. He stressed: "Brand promotion needs a process, including the cultivation of consumers’ habits, the improvement of sales promotion channels and the promotion through professional competitions, and more time and money should be spent on marketing."

  It is a common practice for well-known bicycle companies to participate in competitive competitions and improve brand awareness. For example, both Giant and Merida have a place in the Tour de France, and both have their own named teams, commonly known as "factory teams". Since they are factory teams, they ride their own brand cars, and their exposure is self-evident.

  In order to promote the brand, Xidesheng set up its own intercontinental motorcade many years ago, and used the experience of Giant and Merida for reference to promote its own brand by sending players to participate in various professional competitions. By sponsoring the motorcade, Trinidad has also made its own brand logo on the stage of international competitions frequently.

  In addition to participating in competitive competitions, vigorously laying out domestic and foreign sales networks is also an important measure to enhance brand awareness. Lin Jing introduced that at present, Xidesheng has more than 2,000 specialty stores in China, but less than 20 abroad. The next step of brand layout is to increase efforts to "go global".

  Zhang Xiaoping said that at present, Trinidad has nearly 2,000 sales points in China, and it is going to build the sales points into exclusive stores to enhance its brand image and professionalism. At the same time, it will invest 5 million to 8 million yuan every year to establish image stores in first-tier cities.

  Bicycle enterprises, including Blueprint Technology, Xidesheng, Trinidad and other enterprises, not only vigorously promote offline, but also increase their promotion efforts on online platforms where young people gather, such as bilibili, Xiaohongshu and Aauto Quicker.

  As a permanent national brand, it has gone further on the road of promotion. At the 31st China International Bicycle Exhibition, the booth of Permanent Brand was crowded, and several young people on the stage were playing cosplay. Yan Yiming, Chairman of Shanghai Permanent Bicycle Co., Ltd., introduced that since 2016, he has been cooperating with the glory of the king, Peace Elite and other e-sports across the border to increase the promotion of young people. "Let everyone see that old brands can also be very fashionable."

  The high-quality development of industry needs a good ecology. Since 2010, China electric bicycle and parts industrial base, China famous bicycle town, China bicycle parts and children’s bicycle industrial base, China electric bicycle industrial base, China bicycle parts and children’s bicycle capital, and China electric vehicle industrial base have been established one after another.

  After more than 10 years of key support and supporting construction, the bicycle industry has not only formed a three-legged industrial pattern, but also cultivated four regions with vehicle characteristics and four regions with parts characteristics, covering five provinces and cities in the seven major producing areas of the industry, half of which are national.

  Liu Jun, director of the Bicycle and Electric Vehicle Industry Center of the Industry Promotion Department of Tianjin Ziya Economic and Technological Development Zone High-tech Industrial Park Development Co., Ltd., said that the growth of the industrial chain is like planting crops, which needs fertile soil, sunshine and rain, and also needs to be cultivated. Our goal is to create a good ecological environment in which bicycle enterprises can go up and up again.

  Yang Yufeng always remembers that when he was a child, his father used to ride a bicycle and travel with his family, which attracted the envy of others. Today, he still likes cycling, and he likes the fitness experience and carefree mood brought by cycling.

  The change of a bicycle’s function and function is the epitome of economic development and social progress, and it is also the purpose of traditional manufacturing industry to constantly adapt to market changes and meet consumer demand.

  A bicycle industry, one end of which is connected with the practice of manufacturing a powerful country, and the other end is connected with the people’s yearning for a better life. It is also a supporting industry for regional economic development and an advantageous industry for exporting foreign exchange, and it is a veritable industry for enriching the people and people’s livelihood. In today’s high-quality development, the bicycle industry will climb over more gullies and head for a better future.

Is the earthquake near or far from you? Earthquakes can be made? Please keep these knowledge of earthquake science.

  Is the earthquake near or far from you? Earthquakes can be made? What is earthquake warning? On May 12, 2023, on the occasion of the 15th National Disaster Prevention and Mitigation Day, the reporter visited the Seismological Bureau of Jiangsu Province to learn more about artificial sources, earthquake early warning and how to judge the distance of earthquakes.

  Is the earthquake near or far from you?

  Earthquake! How to "count by fingers" whether the earthquake is near or far from you?

  During an earthquake, the distance from the epicenter to any point on the ground is called epicentral distance. An epicentre distance of 100-1000 km is a near earthquake, and a distance of more than 1000 km is a far earthquake. For example, the Wenchuan earthquake is a near earthquake for Chongqing, which is more than 300 km away. For Beijing, thousands of miles away, it is a distant earthquake.

  The source will produce two kinds of seismic waves in underground rocks: longitudinal wave and shear wave. P-wave, also known as P-wave, is the first to reach the epicenter. Its propagation speed in the earth’s crust is about 6 km/s, which makes the ground vibrate up and down, and its damage is weak. Followed by shear wave, also known as S wave, the propagation speed in the earth’s crust is about 3.5 km/s, which makes the ground shake back and forth and left and right, which is more destructive.

  Seismic waves can be recorded by seismographs. If the distance from the seismograph to the source is expressed as L, then the time to receive P wave can be expressed as L divided by the speed of P wave 6 kilometers per second, while the time to receive S wave is L divided by the speed of S wave 3.5 kilometers per second. The closer the difference obtained by subtracting the propagation time of the two waves, the closer the earthquake is; On the contrary, the farther away.

  For the public, it is easier to judge by the sense of earthquake.

  During an earthquake, we can count from the first time we feel shaking to the second time when we feel shaking stops, and count by the number of seconds. Suppose you count 20 seconds during this period, according to the formula of the time difference between longitudinal wave and shear wave, then the distance between the earthquake and you is about 160 kilometers!

  In addition, when the P-wave and the S-wave propagate to 100 kilometers, they will gradually decay, overlap and interfere with each other, and then develop another wave-surface wave. It propagates along the surface of the earth, with slow energy attenuation and long propagation period, and sometimes it can even circle the earth several times. Because the surface wave period is similar to the natural period of high-rise buildings, people living in high-rise buildings will feel the sloshing is more obvious.

  Don’t be afraid when the earthquake comes, the longitudinal wave and the transverse wave are sometimes different, so there is a way to count by pinching your fingers, and you know whether it is near or far!

  Earthquakes can be made.

  When it comes to earthquakes, many people will turn pale. However, apart from the disaster, we can also explore the interior of the earth through earthquakes: because seismic waves are the only waves that can penetrate deep into the earth.

  However, due to the limited number of natural earthquakes, its location accuracy is not high, and the measurement of underground medium changes using natural sources is limited to some extent. Therefore, the use of artificial seismic sources to actively emit seismic waves into the ground has become the main means to monitor the changes of underground media.

  In 1968, the air gun source was born. Its principle is to release high-pressure air in the water body, causing the vibration of the limited water body, and the huge water body knocks on the ground to excite the seismic wave that propagates outward.

  However, air gun sources are widely used in the ocean and have never been used on land.

  Since 1995, scientists have tested almost all artificial seismic sources that can generate seismic waves on land, including explosives, vibroseis, falling weights, train and subway vibrations, and found that they are not ideal artificial seismic sources.

  In the 21st century, Chinese scientists began to try to introduce air gun sources into land detection, and developed the data processing technology of "micro-excitation", that is, the propagation distance of land bubble sources was greatly increased by superposition, thus further expanding the detection range.

  Since 2006, China has built underwater air gun launchers in Urumqi, Xinjiang, Dali, Yunnan, Xiamen, Fujian, Qilian Mountain, Gansu and Baoji, Shaanxi. If more than a dozen air gun transmitting stations are set up in China to excite seismic waves, long-term continuous large-scale coverage exploration can be carried out in Chinese mainland, and regional large-scale structural exploration and seismic risk monitoring in tectonic active areas can be carried out.

  However, when there is no suitable water body, the artificial source can also be an artificial air gun source made of compressed natural gas (methane). Its principle is that when methane and oxygen are mixed and ignited in a closed container, a detonation reaction can occur, and the high-pressure gas generated by detonation instantly releases the generated seismic wave. Its advantages are safety, environmental protection and high efficiency, and it can be used as a "small beacon" in high-precision shallow underground space exploration and development, and can be used in urban underground space development, site evaluation, seismic activity zone investigation, deep prospecting and so on.

  The "bright light" has already risen, but the road is long and Xiu Yuan. In the future, scientists in China will continue to explore and write the research results of "There is a big dipper in the sky and a bright light in the ground" on the land of the motherland, slowly unveiling the mystery of the earth.

  Aspects of earthquake early warning

  How is earthquake early warning achieved?

  There are two kinds of body waves during earthquakes: longitudinal waves and shear waves. Longitudinal waves run fast and have limited destructive power. Shear waves are slow and destructive.

  After the earthquake, several early warning stations closest to the epicenter will receive p-wave seismic signals one after another, which will trigger the rapid judgment and measurement system of earthquake parameters, quickly measure the time, location, source type and magnitude of the earthquake, predict the intensity of ground movement in the relevant areas, and then use the principle that the speed of electromagnetic waves is much faster than that of seismic waves to send early warning information to different areas before the arrival of destructive shear waves.

  The emergency time obtained by early warning can be used for escape and emergency treatment, effectively reducing casualties and disaster losses.

  However, earthquake early warning also has shortcomings.

  Because the information output depends on the limited recorded signals of observation stations near the epicenter, there are some limitations in earthquake early warning, such as early warning blind area, deviation and false alarm.

  The early warning blind zone means that it takes a certain time for the station to receive the seismic wave and process the information. By the time the early warning information is sent out, the destructive seismic wave has spread for 20 to 30 kilometers. This makes it basically impossible to give an early warning within this radius, and it is precisely in this area that the ground movement is the strongest and the damage is the most serious.

  Take the Wenchuan earthquake as an example, Yingxiu Town, which is less than 20 kilometers away from the epicenter, is in the early warning blind zone.

  If there are few seismic stations in the epicenter and the recorded signals are incomplete, the early warning results may be biased. In practice, it is necessary to revise the results through continuous reporting.

  When a seismic station is disturbed by non-seismic signals, it may also trigger an early warning system and issue an error message. In 2016, Japan misreported strong earthquakes due to lightning interference at individual seismic stations, resulting in short-term suspension of some rail transit.

  Earthquake early warning is the most effective technical means to reduce disasters. With the implementation of the national earthquake intensity quick report and early warning project, the second-order earthquake early warning capability has been initially formed in some areas of China.

  Xinhua Daily Meeting Point reporter Cheng Xiaolin

Indian parliament monsoon meeting is just around the corner, and farmers plan to resume protests.

△ Image from the Internet

  According to Indian media reports on the 18th, Laksh Tikai, the leader of the protest movement against the farmers’ bill, said that they would send 200 farmers to sit in front of the parliament building in New Delhi every day from July 22nd during the upcoming monsoon meeting of the Indian Parliament. Police in New Delhi will hold consultations with farmers’ representatives on the demonstration site on the 18th. The police said they might advise farmers to change the location of the demonstration.

  The monsoon meeting is tentatively scheduled to be held from July 19th to August 13th. Laksh Tikai said that this will be a peaceful protest, farmers will sit outside the parliament, and the parliamentary meeting can proceed normally.

  Indian farmers’ organizations announced to the public that the government has made it clear that it will not withdraw the bill, but the door to negotiations is open. The government said that it was of little significance to hold talks. Farmers’ organizations insist that if the government does not withdraw the farmers’ bill, their protests will last at least one to two years.

  Since the end of November last year, farmers in Punjab, Haryana and Uttar Pradesh in India have been protesting against three bills involving their immediate interests. Farmers are worried that after the implementation of the new law, the original minimum food price guarantee system will be destroyed, and farmers’ interests will be completely at the mercy of agricultural oligarchs.

  So far, the Indian government and farmers’ organizations have held 11 rounds of talks, the last of which was on January 22nd. At present, the Supreme Court of India has requested to suspend the implementation of three controversial farmers’ bills and set up a special committee to find solutions.

I heard that the "flood season" is planning to fight the "active battle" against floods and rescues.

Harbin, China, September 6 (Reporter Ma Junwei correspondent Yang Qikun) Facing the continuous rise of the water level of Wusuli River, under the strong leadership of the county party committee and government of Raohe County, Wulindong Town of Raohe County firmly established the consciousness of "prevention is better than disaster relief", and closely focused on the idea of "it is better to take precautions against nine empty spaces than fail to take precautions in case", and organized all party member cadres, villagers, volunteers and other forces to actively participate.

Leading cadres stick to the front line of flood control by commanding ahead and reserving in advance.

Qiliqin River in Wulindong Town is 4.5 kilometers, and Wusuli River section is 7 kilometers, including 1.6 kilometers in the dangerous area. The party Committee and government of Wulindong Town gave full play to the joint defense linkage mechanism and issued a "red mobilization order" at the first time.

Party and government leaders, Baocun film directors, town and village cadres and other forces went deep into the front line of flood control for the first time, checked the water level, carefully investigated every risk point, and formed a responsibility system of leadership taking the lead, going deep into the front line, linking up and down, joint prevention and control, and ensuring early detection, early reporting and early disposal of dangerous situations.

On the eve of the rainstorm on August 29th, a water cannon was added to drain waterlogging in the ditch for 24 hours, and weeds and branches on the back slope of the dike were cleared for 12.5 kilometers. Piling was carried out on a newly built gate, and 3000 bags of sand and gravel were prepared on both sides of the slope protection and dike.

Reserve 8,000 woven bags for flood control, 100 kilograms of iron wire, 200 shovels, 20,000 square meters of colored striped cloth, 5,000 cubic meters of sand and gravel, and keep life jackets, tarpaulins, headlights and other emergency rescue equipment, and sign an emergency rescue agreement for flood control with 4 hook machines and 2 forklifts to ensure that the materials and equipment are fully prepared, adjusted, transported and used, thus providing a strong material guarantee for flood control and emergency rescue.

Defend the soil and do their duty, and strive to prevent disasters. Grassroots party organizations fight in the front line of flood control.

Wulindong Town insists on flood control and emergency rescue as the touchstone and sharpening stone to test the organizational strength of grass-roots party organizations, constantly refines work measures, makes various emergency preparations, and handles emergencies at any time. To implement the duty responsibility system for flood control, all township and village cadres are required to keep the telephone open 24 hours a day, discover and report special events, emergency floods, disasters and possible major hidden dangers in time, and do a good job in duty records and handover work.

Party member cadres transformed themselves into Depth Charge for flood control and emergency rescue, actively rushed to the front line of flood prevention and emergency rescue, and made every effort to do key work such as hidden danger investigation and dredging waterlogging, so as to ensure safety and people’s livelihood and build an "iron wall" between people and floods.

Not afraid of difficulties and daring to go retrograde, the vast number of party member charged in the front line of flood control

Over the past few days, the town has given full play to the role of party member Volunteer Service Pioneer and New Era Civilized Practice Volunteer Service Team, strengthened the investigation and control of risk points, found signs of danger and responded quickly, and organized support teams to rush to the scene at the first time to eliminate hidden dangers for flood control and disaster relief work in the town.

At the same time, strengthen the early warning and forecasting of rain information, adhere to early warning and forecasting, use WeChat group to convey rain information to villages and households in time, guide cadres and the masses to enhance their awareness of disaster prevention, effectively implement flood control responsibilities, and make every effort to prevent safety accidents.

Strictly implement the 24-hour duty system for flood control, adhere to real-time forecasting and early warning, realize the seamless connection of the responsibility chain of "prevention" and "rescue", build a "red dam" for flood control and flood control in an all-round way, and build a solid defense line for concerted fighting and flood control.

How does the airport deal with tornadoes?

  Zhang Qiang

  Tornadoes are so powerful that they can throw heavy objects on the ground into the air at once. And what if the plane in the air encounters a tornado?

  Most tornadoes occur in the troposphere, where the temperature difference is obvious and the weather is complex and changeable. The cruise phase of large passenger planes is mainly in the upper troposphere or stratosphere and will not be affected by tornadoes. Although in the take-off and landing phase, domestic airports are generally strictly located and will not be built in areas with high tornado incidence, everything happens by accident, and there are also cases where airplanes pass by tornadoes:
        On April 30, 2014, the central part of the United States was hit by a strong tornado, and a helicopter crashed after being sucked by the tornado in the process of chasing the wind.
        In January, 2015, a plane in Lebanon passed by a huge tornado while flying, flying calmly and calmly, as easily as soy sauce. Let’s just say that the pilot is too courageous.
        On June 14th, 2014, there was a small vortex (a tornado that didn’t reach EF0 level) on the North Road of Capital Airport. The decades-old trees on the side of the North Road of Airport were cut off by the waist, and the entrance of the flight corps was a mess …
        In order to deal with these tornadoes that come and go quickly, and other bad weather, Doppler radars are built in major airports in China, and meteorologists monitor strong convective weather such as thunderstorms and hail 24 hours a day. If the Doppler radar finds the "primary embryo" of the tornado or it has been generated, the meteorologists will strengthen monitoring and tracking, analyze which direction these disastrous weather may move according to various data, and then issue weather warnings to those affected routes and airports.
        For this daunting natural phenomenon, "hiding" is the best way to get out of danger. Before the flight, the flight crew will look at satellite cloud pictures, national weather radar puzzles and airport weather reports, understand the actual situation and weather forecast including thunderstorms and related dangerous weather conditions, and comprehensively consider the take-off alternate field, route weather, destination and other alternate field situations.
        For passengers, if they want to know the weather in flight, they can use WeChat WeChat official account "AirportWeather" to extract airport weather reports, airport radar images and satellite cloud images before taking off or after landing. In addition, bumps and injuries at an altitude of 10,000 meters occur every summer. Passengers are advised to fasten their seat belts all the way.

H5, the first car in Shangjie, appeared in the list of the Ministry of Industry and Information Technology and is expected to be listed in September.

On July 16th, in the Announcement of Road Motor Vehicle Manufacturers and Products (the 397th batch) disclosed by the Ministry of Industry and Information Technology, the first car H5 of Shangjie Automobile jointly built by SAIC and Huawei was officially unveiled. As the last "boundary" of HarmonyOS Zhixing, this car focuses on the 200,000-class consumer market, and it is expected to be launched in September, which will become an important model for HarmonyOS Zhixing to explore the mass market for the first time.

Vehicle parameters and power information

The body dimensions of Shangjie H5 are 4780mm long, 1910mm wide, 1657mm high and 1664mm high, and the wheelbase is 2840mm. In terms of power, there are two versions of pure electric and plug-in extended range hybrid power:

The pure electric vehicle is equipped with TZ204XS1352 motor, which has a battery life of 655km, a maximum speed of 190km/h and a total mass of 2395kg.

The extended-range version is equipped with a 15FMC engine, with a comprehensive endurance of more than 1300km, and its emissions meet the national VI standard of GB18352.6-2016.

In addition, the new car provides a wealth of optional configurations, including laser radar, luggage rack (black), rim style, fender trim (black), tail logo, front and rear lower trim (black), etc., to meet the individual needs of different users.

Positioning and core highlights

Shangjie brand is different from HarmonyOS Zhixing’s brands such as Wenjie and Zhijie, focusing on the 200,000-level "volume" market, filling the gap of HarmonyOS Zhixing in the popular market. Its core highlight is that it is equipped with HUAWEI ADS 4 intelligent driving system when it goes on the market. Yu Chengdong, managing director of Huawei and chairman of BG, called it "ceiling-level experience", emphasizing the advantages of the car in the field of intelligent driving.

Sales channels and production capacity layout

Shangjie will adopt an independent private network sales model. At present, there are more than 1,000 channels competing for agency rights, and the progress of channel construction mainly depends on Huawei. Previously, HarmonyOS Zhixing had held a recruitment meeting for the channels of Zhijie and Shangjie private networks to recruit high-quality dealers with 4S operation qualification nationwide.

In terms of production capacity, the production addresses of Shangjie H5 involve Ningde City, Fujian Province, Zhengzhou City, Henan Province, Nanjing City, Jiangsu Province, and Pudong New Area, Shanghai. These cities all have the layout of production bases of SAIC, but some sources said that multi-address labeling belongs to protective filing. In addition, Shangjie vehicle production and battery supporting projects have settled in Shanghai Lingang New Area, providing guarantee for production capacity. Jia Jianxu, president of SAIC, once revealed that the exclusive team of Shangjie has exceeded 5,000 people, with an initial investment of 6 billion yuan, and the two sides will also build exclusive super factories.

Market expectation

The launch of Shangjie H5 is an important achievement of cooperation between SAIC and Huawei. Yu Chengdong had predicted that the sales volume of this car would explode after it was launched, and asked SAIC to prepare sufficient production capacity. The market performance of this car will not only affect the deepening of cooperation between the two parties, but also become a key step for HarmonyOS Zhixing to explore in the popular market. At present, Shangjie Automobile and its shareholders have started to warm up the new car, and the countdown to listing has already started.

General Secretary Supreme Leader’s Visit to Hainan

  Xinhua News Agency, Haikou, April 14th: Standing on the unique advantages and standing at the forefront of reform — — General Secretary Supreme Leader’s Visit to Hainan

  Xinhua News Agency reporters Li Jinhong, Zhao Yeping and Liu Deng

  In Hainan in April, the mountains and seas are blue, and the daily warm wind is light. From 11th to 13th, General Secretary of the Supreme Leader visited Qionghai, Sanya, Haikou and other places successively after attending relevant activities of the 2018 annual meeting of Boao Forum for Asia, and went deep into rural areas, scientific research institutions and government affairs centers to investigate and investigate the economic and social development. Following the footsteps of the general secretary’s inspection, Xinhua News Agency reporters paid a return visit to some cadres and masses who had face-to-face exchanges with the general secretary.

  The economy should develop and health should go up.

  On the afternoon of 11th, the supreme leader first came to the planning hall of Boao Lecheng International Medical Tourism Pioneer Zone. This pioneering zone is the only national development park approved by the State Council in 2013, which mainly focuses on international medical tourism services, low-carbon ecological communities and gathering places of international organizations. It enjoys nine highly valuable opening policies, including allowing overseas capital to set up medical institutions, lowering the import threshold of medical devices and medicines, and relaxing the practice hours of overseas doctors. The establishment of the pioneer zone has injected new vitality into Hainan’s comprehensive opening up.

  "The general secretary carefully inquired about the progress of Boao Super Hospital and the pioneer area, and shook hands with me cordially, which moved me deeply." Academician Li Lanjuan, an infectious disease expert and president of Boao Super Hospital, recalled that when she introduced to the general secretary that the super hospital gave full play to the national preferential policies and actively solved the needs of Chinese people seeking medical treatment and medicine abroad, the general secretary affirmed it.

  Boao Super Hospital was opened on March 31st. It is composed of "a shared hospital (platform) and several clinical medical centers", with diversified investment, market-oriented operation and professional management. Using the special policy of pioneer area, Boao Super Hospital can introduce foreign drugs, equipment and new technologies, which not only faces domestic demanders, but also serves foreign demanders.

  "The general secretary said three ‘ Good ’ Let me be confident. " Li Zhaoshen, an academician of China Academy of Engineering and inventor of Anhan magnetically controlled capsule gastroscope robot, said that the general secretary took over the magnetically controlled capsule gastroscope robot and asked about the clinical use and product advantages while studying it carefully. When he learned that using this robot has the characteristics of painless, non-invasive, no dead angle and no cross infection, it can solve the pain of patients during gastroscopy, and he affirmed it. "The encouragement of the general secretary has made me more confident to continue to do product research and development."

  Fu Ping, deputy secretary of Qionghai Municipal Committee and mayor, said that Qionghai will earnestly implement the general secretary’s requirements, accelerate the infrastructure construction of Lecheng, increase investment and financing, and build Lecheng well so that Chinese people can enjoy high-level medical services in Lecheng without going abroad, and will never live up to the ardent expectations of the general secretary.

  Strive to seize the commanding heights of scientific and technological development

  On the afternoon of 12th, General Secretary of the Supreme Leader came to Sanya to inspect the Institute of Deep Sea Science and Engineering of China Academy of Sciences and the National Nanfan Scientific and Research Breeding Base.

  Zhang Jingjie, an expert on solid buoyancy materials and a researcher at the Institute of Physical and Chemical Technology of the Chinese Academy of Sciences, told the reporter that the general secretary is very concerned about the solid buoyancy materials of the manned submersible "Deep Sea Warrior". "I can deeply feel the general secretary’s concern for deep-sea science and technology. As a frontline researcher, I am very proud and confident to embark on a road of independent innovation."

  Yang Tianliang, director of the Sanya Research Center of the Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, told the reporter that during his inspection in the deep sea, the General Secretary affirmed the achievements made by several scientific research units in Sanya in new technological breakthroughs and institutional innovation.

  "The general secretary’s speech greatly encouraged the researchers present. As a special zone, Hainan should set an example and demonstrate the innovation of scientific research system and mechanism, and enhance Hainan’s scientific research strength as soon as possible through new ideas, mechanisms and practices." Yang Tianliang said.

  Subsequently, the Supreme Leader braved the high temperature of more than 30 degrees Celsius to come to Nanfan Scientific and Research Breeding Base. Hainan is an important crop seed breeding base in China. Every winter and spring, thousands of scientists and technicians gather here from all over the country to breed and produce seeds, and cultivate and optimize the latest crop varieties.

  "When the General Secretary of the Supreme Leader saw me, the first sentence said that your body is still very tough!" Yuan Longping, an academician of China Academy of Engineering and the "father of hybrid rice", told the reporter that he introduced the latest scientific research and innovation of super hybrid rice in China to the general secretary. "The general secretary asked a lot of questions, how about the rice quality of super rice, whether it has been popularized abroad, and how about sea rice … …”

  "I saw the general secretary in Tiantou and greeted him to shake hands. The first sentence of the general secretary was ‘ You’re here ’ Very kind, I am very touched. " Academician Xie Huaan, director of the Academic Committee of Fujian Academy of Agricultural Sciences, said, "When the general secretary worked in Fujian, I was the president of Fujian Academy of Agricultural Sciences, and he attached great importance to agricultural science and technology at that time. The general secretary’s visit to Nanfan base and rice display field shows that he attaches great importance to the country’s grain production and food security and always keeps it in mind. "

  Zhu Renshan, a professor at the School of Life Sciences of Wuhan University and an expert in rice breeding, said that the General Secretary of the Supreme Leader has put forward specific requirements for us, and we will continue to take root in the front line, strive to do a better job in scientific research, cultivate varieties that are more practical and easier to popularize and produce in large areas, and make new contributions to the country’s food security.

  Treat oases and blue waters at sea like life.

  On the morning of the 13th, the Supreme Leader came to the Hainan Provincial Museum in Haikou City to visit the 30th Anniversary Achievement Exhibition of Hainan Special Economic Zone.

  "The general secretary is very concerned about the development of Hainan and will ask questions with concern wherever he goes." Chen Jiang, director of the Hainan Provincial Museum who accompanied the tour, said that the General Secretary was very concerned about the pilot work of "multi-regulation integration" reform in Hainan, tackling poverty, opening to the outside world and the twelve key industries, and asked many questions and learned in detail.

  After the visit, the general secretary came to the Ecological Construction Museum, inspected the samples of the gene bank of tropical marine island plants and animals, watched the real-time monitoring screen of nature reserves, and listened to the analysis of air quality monitoring data in Hainan, affirming Hainan’s practice of attaching importance to ecological environment protection. The General Secretary requested that the protection of the ecological environment should be the fundamental foothold of Hainan’s development, firmly establish the concept of Lucid waters and lush mountains are invaluable assets, treat this oasis on the sea and this blue sea water like life, and strive to make greater achievements in building socialist ecological civilization.

  After leaving the museum, the Supreme Leader took a bus to Hainan Provincial Government Affairs Data Center. "The screen shows ‘ Take care of a fish and half a catty of shrimp ’ The general secretary was attracted by this sentence. " Zhu Qifeng, a staff member of the Hainan Provincial Government Affairs Data Center, said that he gave the general secretary a detailed introduction to the data center’s real-time understanding of seafood prices by using Internet remote monitoring. Once the government price limit is exceeded, the system will immediately report to the police.

  Zhu Qifeng said, according to the requirements of the General Secretary, we should make good use of information technology to really control the price of seafood so that tourists can spend safely when they come to Hainan.

  Hainan Provincial Government Data Center is a microcosm of accelerating the integration of government information systems and the sharing of government information resources, eliminating "information islands" and improving government services and social governance capabilities in Hainan in recent years.

  Dong Xuegeng, chief engineer of Hainan Provincial Department of Industry and Information Technology, recalled that after the General Secretary learned that Hainan’s tourism, disaster prevention and mitigation had achieved remarkable results through the use of big data cloud technology, he requested that information technology should be used to better perceive the social situation, smooth communication channels, assist decision-making and administration, and facilitate the masses to do things, so as to be aware of it.

  "I understand ‘ Know fairly well ’ That is, informatization should play the role of excellent politics and convenience. " Wang Jing, director of the Hainan Provincial Department of Industry and Information Technology, said that according to the important instructions of the General Secretary, in the future, Hainan should use information technologies such as big data to improve its governance capacity and management and control level, and provide information support for the construction of a free trade pilot zone throughout the island, making big data the driving force and new kinetic energy for Hainan’s new round of reform and opening up.

  The key to rural revitalization is to revitalize the industry.

  On the 13th, near noon, the Supreme Leader came to Shicha Village, Shishan Town, xiuying district City, Haikou City against the scorching sun to visit the villagers and inspect the implementation of the rural revitalization strategy.

  "The scene was very hot. There were about 300 people. The general secretary and about two-thirds of the people shook hands and kept saying hello to everyone." Xiao Yuejuan, a villager in Shicha Village, recalled that the scene at that time was still excited. "Thank you, General Secretary, and thank the party and the country for letting us live a good life."

  Xiao Yuejuan told reporters that Shicha Village is located at the foot of the highest volcano in Qiongbei. In the past, due to poor natural conditions, there was no industry in the village and the villagers did not have much income. Many villagers work outside all the year round, and their relatives gather less and leave more. In recent years, the village party branch led the masses to develop Dendrobium industry, explored the road of "enterprise+cooperative+farmer" according to local conditions, and became a well-known star village for developing Internet planting on volcanic rocks, with the per capita net income of farmers exceeding 10,000 yuan.

  “总书记非常关心村民们的生活,问大家的生活过得好不好,收入怎么样。”肖月娟说,她告诉总书记,家里有五口人,6.4亩地入股种石斛,自己在园区就业每个月还有2500元的收入,加上家里其他产业,一年有近10万元收入。

  随后,最高领袖沿着石板路步行来到施茶村火山石斛园。施茶村村民、技术员吴清伟说:“我们向总书记介绍了现代化的智能喷灌技术,只需要在手机上点击开关,就可以给石斛进行浇灌,总书记听完高兴地称赞说这个很方便。”

  “没想到有机会见到习总书记,并和他交流。”施茶村村民、石斛园销售员王朝是一名返乡大学生,他激动地告诉记者,习总书记平易近人,也很幽默。

  村党支部书记洪义乾说,下一步施茶村要牢记总书记的嘱托,紧紧抓住乡村振兴战略,继续加强村党支部建设,带领全村发展集体经济和生态旅游,实现村村有产业,家家有分红。施茶村一定会更上一层楼,老百姓的生活一定会更加幸福。

Fortunately, I didn’t land. How terrible is Typhoon Xuanlannuo?

  With the typhoon "Xuanlannuo" away, the people in the "postal area" breathed a sigh of relief.

  As the first super typhoon in the northwest Pacific in 2022, "Xuanlannuo" has a large scale, a long duration and a wide wind circle, and it goes all the way from the northwest Pacific to the East China Sea … … Fortunately, after crossing the same latitude in Shanghai on the afternoon of September 5, it continued to move northeast.

  Become the "king of the wind"

  "Xuanlannuo" is born extraordinary.

  On the afternoon of August 28th, it was formed in the region of 25.9 north latitude. This is much higher than the latitude of the general typhoon-generating area (5-20 north and south latitude), which is really rare.

  The reason is related to the atmospheric circulation situation and the extreme high temperature this summer. Han Ning, chief service officer of Shanghai Meteorological Bureau, explained: "In the past two months, the subtropical high occupied the northwest Pacific Ocean for a long time, and the downward flow, where the subtropical high prevailed, caused the sea surface temperature to rise sharply, and at the same time, a lot of heat was gathered in the sea, which provided very good thermal conditions for typhoon generation."

  At 15: 10 on August 30, at this time, "Xuanlannuo" has been strengthened to a super typhoon level with clear eyes. Weibo @ Central Meteorological Observatory Map

  Subsequently, "Xuanlannuo" was upgraded from a strong tropical storm level to a super typhoon level within 24 hours (from 2: 00 on August 29 to 2: 00 on August 30). At this time, it has a clear eye, a complete and compact ring structure, a small head but strong strength, and belongs to a "short and capable" strength player.

  From August 31st to the early morning of September 1st, under the influence of Fujiwara effect, Xuanlannuo swallowed the tropical depression on its south side. Weather map of Weibo @ China

  From August 31st to the early morning of September 1st, "Xuanlannuo" accomplished two major events in one fell swoop.

  First, it successfully completed the "eye wall replacement". This is a process of self-structural adjustment that is common in strong typhoons or super-strong typhoons. After the successful replacement, the typhoon eye of Xuanlannuo has changed from small to large, making it easier to maintain its strength.

  On September 2, "Xuanlannuo" lingered and moved less, and its intensity was downgraded. Weather map of Weibo @ China

  The second thing is that under the influence of "Fujiwara effect", it swallowed up the tropical depression on its south side. "Fujiwara effect", also known as "double typhoon effect", usually means that when two tropical cyclones are within 1000-1500 kilometers apart, their rotation paths will be influenced by each other, showing a trend of approaching or even merging.

  "Xuanlannuo" has changed from a "short and capable" typhoon to a "big MAC" typhoon with fuller wings.

  After the subtropical high was split in two, "Xuanlannuo" was in the saddle-shaped pressure field between the east and the west. Because the steering flow was weak, it kept spinning in the same place, which also led to the upwelling of the lower temperature seawater in the deep ocean, and "Xuanlannuo" weakened to the level of strong typhoon.

  At around 11: 00 on September 4, Xuanlannuo was upgraded to a super typhoon again. Weibo @ Central Meteorological Observatory Map

  However, after entering the East China Sea, Xuanlannuo once again absorbed a lot of energy due to the high sea temperature in the East China Sea. At around 11: 00 on September 4, it was upgraded to a super typhoon again. In this regard, Zhou Guanbo, chief forecaster of the Typhoon and Marine Meteorological Forecasting Center of the Central Meteorological Observatory, said that typhoons that reach the super typhoon level in the East China Sea are very rare, and global warming and La Nina phenomenon are the behind-the-scenes drivers that make Xuanlannuo so special.

  V-shaped walking

  The strangeness of "Xuanlannuo" lies in its "V-shaped position". China Meteorological Bureau said that "Xuanlannuo" has taken a unique path for the first time since meteorological records were recorded.

  2-3 days after its formation, "Xuanlannuo" showed rapid explosive growth and moved steadily to the west. This is still related to the stable subtropical high at that time. "The easterly airflow on the south side of the subtropical high, as the steering flow, made the typhoon move steadily westward, which became the trend of its previous movement." Han Ning said.

  Walking, starting from August 31, "Xuanlannuo" gradually turned southwest.

  This is due to the tropical depression it just annexed. Han Ning said that the tropical depression was on the south side of Xuanlannuo, and this "little brother" was annexed and at the same time led Xuanlannuo to move to the southwest, which became the first turning point in its path.

  Then, it happens that there is a high-altitude trough crossing the border in the north. There are low-value system effects on both sides, and the subtropical high is shivering. Unable to resist the attack of two "opponents", the subtropical high appeared "fracture"

  Han Ning made an analogy. "The subtropical high is distributed in strips from east to west, just like we usually knead a dough. From the north and south, two fingers pinch, so that the whole subtropical high belt breaks."

  The subtropical high was divided into two parts, the east and the west, which also opened the northward passage for the typhoon. However, "Xuanlannuo" was once stuck in the saddle-shaped air pressure field formed by the East-West Ring Road, and steering flow was weak, so it had to keep spinning in the east of Taiwan Province to find a breakthrough.

  Two days later, the opportunity came. The western subtropical high weakened, the eastern subtropical high extended westward, and steering flow was re-established. Xuanlannuo took the opportunity to move directly to the north and enter the East China Sea, and its moving speed was gradually increasing. In this way, we have stepped out of the "god walking", that is, the unique "V-shaped walking".

  Typhoon "Xuanlannuo" path. Produced by the Central Meteorological Observatory at 18: 00 on September 5.

  Subsequently, "Xuanlannuo" went all the way north. At 19: 00 on September 5, it is located in the northern part of the East China Sea, about 170 kilometers west-south of Jeju, South Korea. It is expected to move rapidly in the north-east direction at a speed of about 40 kilometers per hour, and its intensity will slowly weaken.

  Bring sultry first.

  Although "Xuanlannuo" didn’t land in Chinese mainland, its wind and rain impact can’t be underestimated, with an impact range of several thousand kilometers.

  "Xuanlannuo" is gradually approaching Shanghai. Originally, I thought that the typhoon could bring down the temperature, but the first thing that arrived was the sultry weather of Huangmei, and "Xuanlannuo" was wrong.

  At 9 o’clock in the morning on September 4, the temperature in Shanghai was close to 30℃, which was quite sunny when there was sunshine, and sultry when there was no sunshine. This is actually caused by the typhoon structure. The typhoon periphery prevails in downward flow, and it will sink and warm up. Coupled with the ultra-high humidity, it will feel sultry and unbearable.

  The typhoon came, and the blue sky, white clouds, dark clouds and showers in Shanghai were broadcast randomly. The sun came out for a while, and then it suddenly rained heavily.

  In this regard, Wu Rui, chief service officer of Shanghai Meteorological Bureau, explained that the external circulation of typhoon is professionally called "spiral cloud and rain belt". On radar and satellite, spiral cloud and rain belt is a bit like the tentacle of eight catching fish, and it will rain heavily where it is thrown. After throwing it, the weather will improve, so don’t be confused by the temporary calm.

  Especially from the afternoon of September 4th, the wind power in Shanghai increased obviously, and it entered the period with the strongest influence of wind and rain.

  Statistics of rainfall from 16: 00 on September 4 to 16: 00 on September 5 show that the rainfall in Shanghai is generally above the moderate rainfall level. There are heavy rains and local rainstorms in Jiading, downtown, Pudong, Fengxian and other areas. The maximum rainfall occurs in Nanhui New Town, Pudong, which is 51.0 mm. In terms of wind power, the maximum gust on land generally exceeds level 6. Among them, Luojing Town, Baoshan is the largest, with an 11-level gale of 28.6 meters per second.

  At 15: 00 on September 5, the center of Typhoon Xuanlannuo was located on the sea about 358 kilometers east of Shanghai, which was 31.3 degrees north latitude and 125.7 degrees east longitude, and had already crossed the same latitude of Shanghai. At 16: 00 on the same day, "Xuanlannuo" weakened to a strong typhoon level.

  Before midnight on September 5, the wind was still strong along the coast of East China. However, with the typhoon away, the impact on the east China coast will gradually weaken, and the people in the "postal area" will breathe a sigh of relief. The combination of typhoon and cold vortex in the later period will also bring obvious rainfall to the northeast.

  The Central Meteorological Observatory predicts that "Xuanlannuo" will move to the northeast at a speed of 35-40 kilometers per hour, and its speed will gradually accelerate and its intensity will gradually weaken. It will land or graze the southern coast of South Korea in the morning of September 6, and then enter the Sea of Japan and move rapidly to the northeast, and gradually degenerate into an extratropical cyclone.

Faith never changes, and the soul of the army never fades.

  Faith never changes, and the soul of the army never fades.

  The Wuhan Cunji Stomatological Hospital of the University of Chinese Academy of Sciences, which opened nearly two years ago, has 12 retired military cadres from Wuhan General Hospital, No.161 Hospital, No.15 Army, National Defense Information University, etc. After taking off their military uniforms, they still maintain their true colors and feelings as soldiers.

  On the occasion of the Army Day, Wuhan Cunji Stomatological Hospital of the University of Chinese Academy of Sciences, a hospital with deep "military feelings", held a large-scale public welfare activity to support the army and provide "three exemptions and one supplement" medical services for soldiers and their families.

  Do not forget your initiative mind adheres to the purpose of serving the people.

  Wang Linhu, vice president of Wuhan Cunji Stomatological Hospital, secretary of the Party branch and director of the Department of Implant Restoration. He was admitted to the Fourth Military Medical University in 1997. After graduating from the university, he was assigned to work in the Department of Stomatology of Wuhan General Hospital of Guangzhou Military Region, and then studied for master’s and doctor’s degrees at his alma mater and Wuhan University. In life and when receiving patients, he often wears a modest smile on his elegant face, and he can’t see the roughness of the man in Guanzhong at all, but he is serious, cautious and meticulous when treating patients.

  In 2016, Wang Linhu went to an island for joint logistics support. The island lacks medical equipment. He treated the soldiers’ teeth because of his simplicity, and realized the first medical case of tooth extraction and filling in the island, which was well received by the head of the naval headquarters. In another rescue of soldiers, Wang Linhu suffered a broken toe due to an accident.

  Iron camp, flowing soldiers. In 2018, Wang Linhu, who won many honors in the army, such as outstanding Communist party member and third-class merit, decided to change jobs due to physical reasons such as a broken toe. He didn’t lie on the credit book for treatment, but chose to choose his own job and came to Wuhan Cunji Stomatological Hospital to serve more patients and relieve the suffering of the people.

  When he was in uniform, Wang Linhu put responsibility and mission above everything else; After taking off his military uniform, Wang Linhu also maintained his true colors and feelings as a military doctor. 67-year-old Aunt Wang lost all her teeth. Wang Linhu carefully designed the treatment plan, and after fully communicating with the patient, he carried out the traditional maxillary half-mouth restoration and mandibular implant-covered restoration. After the operation, Aunt Wang found the pleasure of eating easily and freely that she had lost for many years.

  On August 4th, Wang Linhu, as an advanced model, shared his experience of self-employment in the adaptability training course for demobilized military cadres in Wuhan in 2019.

  Wang Linhu is just a microcosm of 12 retired military cadres in Wuhan Cunji Stomatological Hospital. In addition, Liu Suping, the assistant to the President of the 161 Hospital, and other demobilized military cadres stick to their positions in hospital medical care and management, and protect the oral health of the people with superb medical skills and excellent military style.

  Maintain true colors and help fight the tough battle of health and poverty alleviation

  Without national health, there will be no overall well-off society. Health poverty alleviation is an important battle in the tough battle against poverty, and returning to poverty due to illness and causing poverty due to illness are the main direction of poverty alleviation.

  In the new battlefield, Wang Linhu people, bearing in mind the teaching of "obeying the Party’s command, winning battles and having a good style of work", give full play to the academic and medical technical advantages of Wuhan Cunji Stomatological Hospital of University of Chinese Academy of Sciences, and take health poverty alleviation and health knowledge popularization as their responsibility — — They successively provided free implants for a 65-year-old retired soldier in Wuhan who won the first-class merit in the self-defense counterattack against Vietnam and an 84-year-old "old soldier" in Xiantao City. They also insist on repairing dentures for the elderly free of charge when they go to retired cadres and other units to carry out health consultation and free clinic.

  On July 1st this year, they organized medical staff to go deep into xiaohe town, Xiaochang County to carry out health lectures, free clinics and medical delivery activities, and conducted a special education activity on health and poverty alleviation in party member.

  In 2018 alone, Wuhan Cunji Stomatological Hospital went deep into 396 communities and more than 300 kindergartens to conduct health talks and oral health examinations, providing free dental fluoride or pit and fissure sealing for more than 20,000 children, and popularizing health knowledge for more than 200,000 people.
