In order to further enrich the resources such as exhibitions, lectures and social cultural relics appraisal of Pudong History Museum, recently, Pudong History Museum and Shanghai Collection Association held a series of activities of co-construction and co-education in the museum.

More than 100 guests, including relevant personnel from Shanghai Collection Association, Pudong New Area Cultural Relics Protection Management Office, Pudong History Museum and cultural enthusiasts, participated in the day’s activities. On that day, the folk treasure-hunting activities were the most popular, and the organizers specially invited Zhu Li, former general manager of Shanghai Cultural Relics Store, distinguished professor Shen Asia, researcher of Shanghai Museum and ancient conservatory of Fudan University. They are all famous experts in antique art appraisal. Many collectors at the scene heard the news and came out with their own collections for experts to appreciate.

Most of the objects brought by collectors are ancestral objects, including porcelain, calligraphy and painting, ancient coins and many other categories. Through the professional guidance and appraisal of experts, everyone has a new understanding of their "baby". Many participants said that it is still meaningful to invite experts to treasure in the museum, hoping that Pudong History Museum can provide more opportunities for appreciation and exchange for folk collectors.

The single pedal mode, which was once to be stopped, has now ushered in a new turn.

Recently, the Ministry of Industry and Information Technology has publicly solicited the opinions of the mandatory national standard of "Technical Requirements and Test Methods for Passenger Car Brake System", and relaxed the relevant specifications of "No complete braking with one pedal". The opinion is clear. In the default working state, the braking effect achieved only by releasing the accelerator pedal should not slow down the vehicle to stop, but the user is allowed to use the single pedal mode to adjust to the state of being able to stop through the option. In the single pedal mode, the vehicle is forced to move, and the brake light must be on.

What is the single pedal mode?

Undoubtedly, this change immediately triggered a hot discussion on the Internet, and the question of whether the single pedal mode should be banned came back. What exactly is the single pedal mode?

In fact, it only needs to understand the logic of the single pedal mode. To put it simply, this mode is still equipped with an accelerator pedal and a brake pedal like an oil car, but in many cases, users can drive through the accelerator pedal. Generally, when accelerating, the user only needs to step on the accelerator deeply; When the user needs to slow down, releasing the throttle will have a braking effect, which means reducing the braking action.

In this mode, many riders feel that trams will be easier to drive than oil cars. After all, with this function, stop-and-go driving in urban areas can generally be completed only by operating the throttle, which saves a lot of braking action and relieves the fatigue of switching pedals back and forth. Coupled with the use of this function, kinetic energy can be recovered, which can save energy consumption to a certain extent, which is more attractive for electric car owners.

Is the single pedal mode good or bad?

As a representative of the single pedal mode, Tesla is undoubtedly the leader in pushing this technology to the public’s field of vision. However, despite its many benefits, the call for "canceling the single pedal mode" has always been very loud.

In the eyes of opponents, this model will make many users make the mistake of inertia thinking. Although it stands to reason that when you release the throttle, you will have a braking effect. But the consequence is that when you put your right foot on a pedal for a long time, you will subconsciously change the muscle memory habit of driving over time, and after an emergency, it is very likely that the accelerator will be used as a brake, which leads to the accident of stepping on the wrong pedal, which is also the source of Tesla’s frequent "brake failure".

In this way, in order to improve the safety of driving, canceling the single pedal mode can really put an end to future troubles. However, this new regulation does not completely "prohibit" the single pedal mode. On the contrary, manufacturers can introduce models with single pedal mode, but only if the single pedal cannot stop the vehicle by default, and the driver needs to adjust the settings himself.

Of course, the reason for this regulation is that it has been considered in many ways. After all, the single pedal mode is not a technology that does no harm at all, such as reducing driving fatigue, reducing leg burden, improving endurance and so on. If it is "one size fits all", it will still be very disappointing for some drivers. After all, everyone is an independent individual, but in reality, there are indeed many users who like the single pedal mode, especially in urban transportation, the single pedal mode has a more natural braking effect than the traditional brake. If you don’t like it, you can also adjust the settings yourself to improve the safety of driving. For example, Tesla is constantly improving this function. Now its single pedal mode can be adjusted by simple settings and become more humanized.

Write it at the end

Whether to cancel the single pedal mode is actually more like a "game" between technology and safety. After all, the single pedal mode is really convenient anyway, which is why Tesla advocates it. In addition to technological innovation, car companies and consumers need to put safety in the first place. Even if they don’t use this model, they will always be alert to braking, otherwise it may lead to a painful tragedy.

1905 movie network news Directed by Bao Beier, the comedy action film starring Clara, Xu Juncong, Yijun Zeng and Menglu Zhang, starring Guo Jingfei, Yasuaki Kurata, Ryu Kohata, Qi Yuwu and Wen Juan, and featuring Song Jia and Yoko Lamu will be released nationwide on September 30th. The film released two ultimate posters today. In the posters, the article and Bao Beier, two heavy agents, sometimes hung on the plane and sometimes rode motorcycles to break through billboards. The thrilling and exciting scene was matched with their oversized bodies, which subverted people’s cognition of traditional agents and was full of joy.

　

The whole lineup of the film made a surprise appearance in the "Drama Group" to show their talents.

　In front of the vertical poster released today, the article and Bao Beier are holding the helicopter with all their strength, vowing to complete the spy mission. On the billboard behind the poster, Guo Jingfei puts his hand over his chest, which seems to be steady and kind, but it is quite different from the cruel and fierce image in the film. The article and Bao Beier’s expression are in sharp contrast with Guo Jingfei’s ease. In the horizontal poster, the article and agents J and Hao Yingjun, played by Bao Beier, rode motorcycles and rushed out of the huge advertising background board, which was thrilling. The article in the poster holds a stun gun and smiles at the camera, which seems to be full of confidence in this spy mission. Bao Beier tried to catch the flying stun gun. Next to Guo Jingfei, Clara, Yoko Ramo, Xu Juncong, Yijun Zeng and Menglu Zhang were armed with different weapons, and the task of special agents was imminent.

In order to attack the National Day file with laughter, director Bao Beier has a unique idea in the choice of actors. As soon as the cast was exposed, some netizens said that the film had a "theatrical troupe". It is reported that this is the second cooperation between the article and Bao Beier’s two old friends. In the face of Bao Beier’s invitation, the article helps each other. Guo Jingfei, who is also a good friend, also said that he was "dug" by Bao Beier during the Chinese New Year; Clara, the sexy goddess, plays Bao Beier’s wife in this movie. Bao Beier said that she had seen Clara’s works in the cinema and was impressed by it, so she was specially invited to cooperate. As for Yoko Spicy and comedian Xu Juncong, who appeared in the film for the first time, the director once saw their performances and found them very suitable for the roles in the film. In addition, the film also brings together many actors with their own characteristics, such as Yijun Zeng, Menglu Zhang, Song Jia and Yasuaki Kurata. What kind of sparks will they collide when they get together, which is really expected.

　

Heavy agents with stunts "maximum size" roadshow campus relay

"Fat Man Action Team" tells a series of ironic and dangerous crisis stories in order to complete a special task played by agent J and security guard Hao Yingjun played by Bao Beier. Different from the usual handsome and vigorous agents, this article and Bao Beier weigh 300 Jin and 290 Jin respectively in the film, and the image of the "XXXL version" is impressive. In the film, the two have to shoot many fierce action scenes such as catching helicopters and backflips with a weight of 200 kg each, which is extremely hard; In addition to high-risk action scenes, two heavy agents even danced "sauce and tofu dance", and the magical songs and flexible dances also attracted many netizens to imitate.

The film "Fat Man Action Team" and "Maximum Size" roadshow are also in full swing. Next, Bao Beier, the director and starring role, will take Yoko Spicy Eye, one of the leading roles in the film, into the university campus to share the interesting things before and after the filming with the students who are in military training. Bao Beier will also dance "Sauce and Tofu Dance" with students, and heavy agents and new "agents" will make a reservation as prom friends. Previously, the founders had held meetings in Shijiazhuang, Changchun, Nanjing and other multi-city shopping malls, tasted local food on the spot, interacted closely with enthusiastic fans and took photos. The director of the "Biggest Code" roadshow will take the film into more than 30 cities across the country, covering the southeast and northwest, aiming to bring infinite joy to the national audience.

The movie "Fat Man Action Team" will hit the national cinema on September 30th.

　　[Tian Chengping, Minister of Labor and Social Security and Director of the Forum Organizing Committee]: Ladies and gentlemen, good morning! In Beij’s golden autumn, we ushered in that second China social security forum, where Chinese and foreign representative got together to discuss the establishment of a social security system covering urban and rural residents. On behalf of the Ministry of Labor and Social Security and the organizers, I would like to extend my warm welcome and sincere thanks to the Chinese and foreign friends who have come to participate in the forum!

　　The theme of this annual forum is to establish a social security system covering urban and rural residents, which is an important issue in the process of China’s socialist market economy development and modernization and an important task to speed up the construction of social security system. The Party and the government have always attached great importance to social security. The Sixth Plenary Session of the 16th CPC Central Committee clearly stated that a social security system covering urban and rural residents will be basically established by 2020. This is an inevitable requirement of implementing Scientific Outlook on Development and coordinating urban and rural development, an important content of maintaining social fairness and justice and promoting social harmony, and an inherent requirement of safeguarding the fundamental interests of the people and following the law of social security development. Just now, State Councilor Hua Jianmin profoundly expounded the importance of perfecting the social security system, put forward the policy of social security system construction, and defined the main tasks of establishing a social security system covering urban and rural residents, which is of great guiding significance for doing a good job in social security work in the new period. We must fully understand and correctly grasp the important position and role of establishing a social security system covering urban and rural residents in the overall economic and social development, and earnestly implement it.

　　After years of practical exploration, China’s social security system reform has accumulated valuable experience in many aspects, and the basic system has become increasingly mature, which has reached a critical period of stereotypes, stability and sustainable development. Party committees and governments at all levels attach great importance to it and are widely recognized by all sectors of society, which provides a strong organizational guarantee for doing a good job in social security. The sound and rapid development of the national economy, increasing comprehensive national strength and accelerating the construction of the public finance system have laid a good foundation for further improving the social security system. At the same time, we should be soberly aware that there are still many hot and difficult issues that people and society pay attention to in the field of social security in China, and we will also face severe challenges such as aging population, diversified employment forms and urbanization. To solve these problems and meet these challenges, the masses have reacted strongly, and all sectors of society are full of expectations. We must seize the favorable opportunity, make full use of favorable conditions, deeply understand the urgency and arduousness of establishing a social security system covering urban and rural residents, adhere to the principle of "wide coverage, basic protection, multi-level and sustainable" based on China’s basic national conditions, constantly improve security projects, steadily improve the level of treatment, further broaden financing channels, speed up standardized management services, and gradually establish a social security system covering urban and rural residents, so that the broad masses can enjoy the fruits of national development and progress. Through our unremitting efforts, we will effectively transform the process of improving the level of economic and social development into a process of constantly improving the social security system covering urban and rural residents.Turn the process of promoting the development of social security into a process of continuously improving people’s well-being and promoting social harmony. To establish a social security system covering urban and rural residents, we must grasp the following basic principles and main tasks:

　　First, both urban and rural areas should be treated differently, and institutional arrangements should be made for the social security of various urban and rural residents. China’s urban and rural social security development is unbalanced, the rural old-age security system lags behind, and the situation of lack of medical care and medicine is outstanding. Most areas still basically stay in family security. In cities, some residents have not been included in the scope of social security, and the social security system needs to be further improved. We must co-ordinate the construction of urban and rural social security system, gradually bring all kinds of urban and rural residents into the coverage, and realize all kinds of insurance; In view of the trend of population mobility and urbanization, we will formulate ways to gradually connect various social security policies and standards in urban and rural areas. At the same time, in view of the dual structure of urban and rural areas, we should fully consider the differences in economic and social development between urban and rural areas, and implement different social security projects between urban and rural areas to reflect the differences in social security levels. At present, the key tasks are: to further improve the social insurance system with the basic old-age insurance for urban workers, basic medical insurance for urban workers and residents, unemployment insurance, industrial injury insurance and maternity insurance as the main contents, and to reform the old-age insurance system for government agencies and institutions; Pay close attention to the study of endowment insurance methods for migrant workers that are in line with the characteristics of migrant workers and can be linked with the current endowment insurance system, and promote migrant workers to participate in work-related injury insurance and medical insurance; Promote the construction of new rural cooperative medical system and explore the establishment of rural endowment insurance system; Encourage and guide the establishment of enterprise annuity and supplementary medical insurance system; To study the basic living security measures for difficult collective enterprises and unemployed elderly people who have not participated in endowment insurance in cities and towns;For urban and rural residents who have failed to participate in social insurance or are still poor even after participating in social insurance, the minimum living security and social medical assistance system for urban and rural residents will be established. 　[10:21]

　　Two, strengthen the government responsibility and fulfill the obligations of units and individuals, highlight the fair effect of social security, taking into account the efficiency of system operation. China’s social security operation and management system is still not perfect, with narrow coverage and low level of overall planning. It is difficult to transfer and continue the social insurance relationship, and the tripartite financing mechanism of the government, employers and individuals needs to be further strengthened. We must further strengthen the government’s management of social security, give full play to the government’s functions of regulating income distribution, maintaining social equity and providing equal public services, and earnestly perform government duties. At the same time, it is necessary to ensure that rights correspond to obligations, earnestly fulfill the social responsibilities of units, fulfill individual payment obligations, attach importance to the efficiency of social security system operation, and establish a benign operating mechanism. At present, the key points are as follows: according to the requirements of establishing public finance, increasing investment in social security, constantly increasing the proportion of social security expenditure in government financial expenditure, especially focusing on solving the transformation costs of some employees’ resettlement and social security in the reform of state-owned enterprises; Strive to basically realize the provincial-level overall planning of endowment insurance in China in about two years, standardize the overall management methods, and clarify the responsibilities of governments at all levels; Further strengthen the management of collection and payment, strictly implement the system of social insurance registration and payment declaration, strengthen audit and supervision and law enforcement, and ensure that all funds should be collected; Establish and improve the fund supervision system such as internal control, information disclosure and information reporting system, improve the working mechanism of the social security supervision Committee, and increase the fund supervision; To study and formulate unified management measures for fund investment and operation,Maintain and increase value through various investment portfolios; Strengthen policy propaganda and supervision of law enforcement, improve the legal awareness of social security, and promote units and individuals to pay insurance premiums; Further improve the method of linking pension, medical care and unemployment insurance benefits with payment, encourage employees to work more, participate in insurance and enjoy more benefits, continuously expand coverage and increase fund income.

　　Three, based on the current and long-term, focus on solving outstanding problems left over from the system transition, and actively establish a long-term mechanism of social security. In the process of promoting the construction of China’s social security system, we are faced with some prominent contradictions involving the vital interests of the masses and a series of major problems affecting sustainable development. There is still a big gap between the degree of social security and the growing needs of the masses. We must base ourselves on the current situation and actively take measures to solve the problems left over from history. At the same time, we should focus on the long-term, accelerate the pace of system reform and innovation, and achieve sustainable development. At present, the key points are: focus on solving the outstanding problems left over from the system transition, and conscientiously implement the continuous adjustment of the treatment of enterprise retirees from 2008 to 2010; Effectively promote employees and retirees from difficult enterprises to participate in medical insurance; Study and improve the specific measures to solve the problem of "old industrial injury" treatment for employees; Conscientiously implement the resettlement and social security policies for employees of closed and bankrupt enterprises, and promote the solution of the problem of wage arrears of employees in difficult enterprises; Conscientiously implement the social security policy for land-expropriated farmers, and earnestly ensure that they are guaranteed upon requisition. The key points of establishing a sustainable social insurance system are: adhering to the old-age insurance system model combining social pooling with individual accounts, continuing to expand the pilot scope of implementing individual accounts, and strengthening the collection and management of funds; Establish a normal pension adjustment mechanism according to economic development and changes in wages and prices of employees, so as to keep the pension benefits of retired employees at a reasonable level;Gradually establish the adjustment mechanism of minimum living standard, unemployment insurance standard and minimum wage standard, so as to form a reasonable proportional relationship among them; Continue to expand the expenditure scope of unemployment insurance fund to better play the role of promoting employment; Actively explore the establishment of a trinity of "prevention, rehabilitation and compensation" industrial injury insurance system, and give full play to the role of promoting industrial injury prevention and rehabilitation.

　　Four, pay attention to the system construction and strengthen the management, and constantly improve the level of social security management services. Strengthening system construction is an important guarantee for establishing a social security system covering urban and rural residents, but the management can’t keep up and the system is difficult to implement effectively. With the continuous development of the cause, especially after a large number of flexible employees, migrant workers and urban and rural residents are included in the scope of social security, the scope, content, objects, projects and methods of handling management have changed greatly, and the problem of insufficient handling management services will become more prominent. It is urgent to strengthen the capacity building of social security institutions and improve the level of management services. At present, the key points are: adhering to the people-oriented concept, formulating the service standards of social insurance agencies and standardizing the construction of service facilities, strictly working procedures, and promoting the standardization, informationization and specialization of management services; Further enrich the handling service team, strengthen the construction of social security organizations in urban communities and towns, and improve the handling conditions; Accelerate the pace of information system engineering construction, so that the insured can enjoy more convenient and efficient services; Vigorously develop the service industry for the elderly and accelerate the construction of public service facilities and service networks for the elderly.

　　Five, not only to speed up the construction of the legal system, but also to pay attention to supervision and law enforcement, so as to provide legal protection for the establishment of a social security system covering urban and rural residents. Social security is a social and economic system enforced by national legislation. By formulating and implementing social security laws and regulations and strengthening supervision and law enforcement, it will further promote the realization of the mandatory, standardized and unified social security system. At present, China’s social security legislation still can’t meet the needs of career development, important laws such as social insurance have not been formulated, and there is no legal basis or insufficient legal effect level in practical work. At the same time, the labor security supervision and law enforcement is relatively lagging behind, and the law enforcement power is weak, which affects the effectiveness of laws and regulations. After years of practical exploration, the framework of China’s social security system has basically taken shape, and the time is ripe to upgrade the policies and measures that have been proved to be effective in practice into laws. We must pay equal attention to speeding up the construction of the legal system and strengthening supervision and law enforcement, and push social security work into the track of legalization. At present, the key points are: further promoting the legislative process of the Social Insurance Law; Pay close attention to the revision and formulation of relevant laws and regulations; Gradually expand the scope of supervision and law enforcement, improve supervision procedures, improve law enforcement agencies, strengthen the construction of law enforcement teams, and increase the investigation and punishment of illegal acts.

　　Ladies and gentlemen, comrades, there are still many key and difficult problems in establishing a social security system covering urban and rural residents. In particular, some tendentious and forward-looking problems will bring us severe challenges, which require in-depth study in theory and bold exploration in practice. It is hoped that experts and scholars will closely integrate with reality, strengthen theoretical research, strategic research and research on major issues, and put forward valuable opinions and suggestions to provide theoretical support and policy reserves for the development of social security. It is also hoped that practical workers will be brave in exploration, bold in practice, constantly sum up experience, accelerate the innovation of social security system and mechanism, and make due contributions to building a harmonious socialist society and a well-off society in an all-round way.

　　I wish the second China Social Security Forum a complete success! Thank you!

As a compact car, Volkswagen Sagitar has been favored by many Chinese people because of its outstanding size. At present, the 2023 model has been on the market for some time and is on sale with its peers. Compared with the old models, Powertrain will provide three options, adding a 1.5T turbocharged engine. The manufacturer’s guide price is between 127,900 and 172,900, and the starting price is cheaper than the 2022 model. The manufacturer’s guide price of the old models is between 133,500 and 165,900. Let’s talk about it with you. What’s the difference between the new and old models?

From the appearance point of view, the new sagitar is more futuristic. The biggest change is the shape of the front grille, which will be consistent with the new Passat in design, with a splendor design and a silver decorative strip in the middle. The headlight group has little change in shape, but it is more powerful in function, adding rain and fog mode and IQ.Light intelligent lighting system.

From the size point of view, the 2023 sagitar has a further size, with the length and width upgraded to 4791×1801×1465 mm, and the wheelbase of the car body remains unchanged at 2731 mm. On the other hand, the size of the 2022 model is 4753×1800×1462 mm. There is no big adjustment on the side lines, and the rearview mirror function will be more intelligent. For example, the blind spot monitoring function will be added. Looking at the bottom, the wheel hub is still 18 inches, and the shape remains unchanged.

At the rear of the car body, there are more adjustments in details, such as the tail wing, and the new model is more three-dimensional. For example, under the surrounding exhaust decoration, the reflector is changed to through treatment, and the face value is more eye-catching.

Entering the car, the new sagitar technology sense has been enhanced, and the central control screen has been upgraded to 12 inches, which looks much bigger than the old one, and supports the car networking function, which is more in line with the needs of the times. The change of full LCD instrument screen will be smaller, the UI will be more traditional, and the dual barrel elements will still be used. The steering wheel has become thicker, the middle family logo has been flattened, and the high-profile models have the steering wheel heating function.

In terms of power, the new sagitar provides a 1.5T turbocharged engine version with a maximum power of 118kW and a maximum torque of 250 N m.. The mid-low model still uses 1.2T turbocharged engine and 1.4T turbocharged engine, which are consistent with the 2022 model in terms of parameters. The maximum power is 85kW and 110kW respectively, and the maximum torque is 175N·m and 250N·m respectively.

In the end, I personally think that buying a car means buying something new instead of buying something old. The upgrade range of the new sagitar is not small, which is more advantageous than the 2022 model. What are your different views and opinions on this? You can leave a message for discussion.

　　Cctv newsAccording to the China Manned Space Engineering Office, at 8: 11 Beijing time today (July 4, 2021), astronaut Liu Boming successfully opened the exit door of the node module of Tianhe core module. As of 11: 02, astronauts Liu Boming and Tang Hongbo, dressed in a new generation of "Feitian" extravehicular spacesuit independently developed by China, have successfully left the space station from the node module of Tianhe core module, and have completed the work of installing the foot limiter and the extravehicular workbench on the robotic arm. With the support of the robotic arm, they will cooperate with each other to carry out the related equipment assembly work outside the space station. In the meantime, Nie Haisheng, an astronaut in the cabin, cooperated and supported two astronauts to carry out extravehicular operations.

　　What tasks did the three astronauts perform in this extravehicular mission? How is the division of labor between them?

　　Two astronauts left the cabin and one conducted cooperation in the cabin.

　　The extravehicular mission was jointly carried out by three astronauts, two of whom changed their extravehicular spacesuits and one astronaut performed command and cooperation tasks in the cabin.

　　Lift panoramic camera position to verify autonomous emergency return

　　The mission of extravehicular activity is mainly to lift the position of panoramic camera outside Tianhe core extravehicular activity, and verify the ability of emergency return in case of emergency. The extravehicular activity was completed by two astronauts AB. After the extravehicular activity, astronaut A was taken to the operating point by the mechanical arm and stood on the mechanical arm to complete the operation. Astronaut B crawled to the operating point autonomously outside the cabin to assist astronaut A on the mechanical arm to complete the operation.

　　It takes about six hours for astronauts to complete this extravehicular task, 2.5 hours for preparation and one hour for operation. In addition to lifting the position of the panoramic camera, it is also necessary to verify the emergency return. This work will be done by astronaut B.

　　There were two extravehicular operations during the Shenzhou-12 mission.

　　During the Shenzhou-12 mission, three astronauts will complete two extravehicular operations, which is also a key technology that must be mastered in building a space station.

　　PG One, head of the on-orbit maintenance technology laboratory of manned spacecraft in the Fifth Academy of Aerospace Science and Technology Group:Extravehicular activities, whether in the International Space Station or the China Space Station, are actually a necessary technology for on-orbit assembly and construction. Now we are assembling and building the space station in the cabin, lifting the camera bracket, which is equivalent to perfecting our infrastructure, and the follow-up may be a lot of experiments in space.
