Car buying boom detonated May Day.

After the sales period of the "Guoliu A" model was extended, the "price reduction storm" in March slowed down, and the promotion policy in April was no longer crazy. Under the current situation that the inventory pressure is still great, consumers who are still on the sidelines are the "problem" and "antidote" of the terminal consumer market.

The first wave of small climax of Qingdao automobile consumption detonated by the West Coast International Auto Show in March, many brands also indicated that they are bound to launch a general attack on inventory pressure at the Spring Auto Show in May. With the approach of the exhibition, the audience’s call for consultation also focused on "preferential policies for XX models at the auto show".

In order to cooperate with the promotion activities of various brands at the Spring Auto Show, and to give back to the support and love of fans and friends, the organizing committee will also launch a "car lottery" on the spot, giving away gifts such as refrigerators, color TVs and high-end cars, such as window film!

As the opening of the exhibition approaches, brands can’t help but lock in the mood of prospective car buyers in advance and release preferential policies one after another.

Geely Auto Show offers a limited time discount of 45,000 yuan;

Lorenz offers multiple discounts. The auto show went straight down in a limited time, up to 50,000 yuan; Pre-stored 2023 yuan intentional gold deducted 20000 yuan car purchase; You can also enjoy the factory subsidy policy;

Changan Auchan’s highest cash dropped by 17,000 yuan;

……

Dongfeng Citroen, which set off the storm of price reduction in March, brought the modified version of Versailles, Tianyi and C6 to this exhibition. What kind of preferential policies will the site come up with? Citroen said that it would sell you a pass first.

The tip of the iceberg began to emerge. It is conceivable that the scene of Qingdao International Auto Show will be so hot from April 28th to May 3rd.

In this exhibition, the organizing Committee specially invited 100 "little reporters" to the scene to touch the latest automobile technology and inject "car dream" into their dreams.

　　Hualong. com at 8: 10 on September 25th (Chief reporter Huang Jun) After 20 days in Cao Yunjin, Degang Guo finally wrote a post in Weibo to respond to the grievances between the master and the apprentice. Many people think that Degang Guo is fighting back, only to find that he left a meaningful sentence at the end of the article — — "In the future, if there is a horse riding high and running short, and there is no one to solve the problem, I don’t care, I care about you."

　　Why didn’t Degang Guo respond before? Degang Guo said, in terms of Cao Yunjin’s cultural level, it is not easy to write down these 6,000 words slowly, even if you read them. Trying to figure out the scene at that time was about one person’s dictation, everyone’s help, someone’s input, and collective polishing. "I have to respond to every composition. If I come to this novel, I will be exhausted."

　　Degang Guo believes that this incident is also regarded as cyber violence, and now cyber violence has reached its peak. "A group of people to scold and scold, there is no bottom line. Good or bad, true or false is not important to them. The key has another point to vent, which is really happy. People need to vent in an environment without consequences, which shows how unsatisfactory life is. These outstanding talents, listening to the wind is rain, really think that they are caught, biting their mouths and shaking their heads. "

　　This time, Degang Guo refuted and responded to Cao Yunjin’s earlier long articles one by one. For example, he thinks that teaching cross talk is different for each apprentice. Because everyone’s understanding and expression are different. "I taught He Wei" Spitting Lotus "not to let Xiaojin attend, and I didn’t let others listen when I taught Xiaojin. This is a teaching method, not an experience of oppression. "

　　Degang Guo also praised Xiaojin for his cleverness and cross talk, and sincerely hoped that he would become popular. Create opportunities to praise him, take him to do programs, and give him a special cross talk, which is slowly becoming popular.

　　"People’s ambitions are constantly expanding with the change of position, and no one is no exception. One of Xiaojin’s favorite words after drinking is: I support half of Deyun Society! I don’t know where to start with this sentence until today. For a time, the younger brothers didn’t even dare to talk to him in the background. When they met opposite, they had to stop and bow respectfully to greet him. The expression of greeting was not good, and they had to be carried to him again. Whoever doesn’t praise him and treat him as a god will be scolded and threatened. During the second enrollment of Crane Word Department, the teachers held a meeting on the second floor, but they didn’t agree. Xiaojinju punched Mr. Xie Tianshun. Mr. Xie is a cross talk treasure, and he is the same generation as Mr. Hou Baolin. Three generations older than Xiaojin, he should call bodhi old zu. But he regarded his seniority as dirt and dared to fight against his ancestors. Later, Xiaojin met an investor who was said to be rich. In my impression, this investor can be close to the people. He can eat two boxes of lunch in the background and watch the fragrance. This gentleman was later sued for slandering a movie star, which shows that his work is very busy. Anyway, after Xiaojin knew this bento tycoon, he became even more unscrupulous and felt that he had a backer. At this time, his face became more and more ugly … …” Degang Guo pointed out that since 2009, Xiaojin has basically stopped performing in a small theater. He went outside to take pictures and do private work, and he earned money by himself.

　　Later, Degang Guo also described in detail the whole story of their war.

　　"All this until January 18, 2010, my birthday, finally had an outbreak. In Guo Jiacai, Sanlitun, all the people of Deyun Society gathered together. Xiaojin shouted at everyone with wine and madness. And shouted: I quit! Zhang Deyan, the daughter of Mr. Zhang Wenshun, begged Xiaojin to come back and said, Please look at my father’s face! Xiaojin shouted: I don’t fucking look at anyone! Turning and walking to the door, I knelt in front of the statue of Guan Gong in the front hall and said loudly, Master Guan is my witness. If I go back to Deyun Society, I will be a * *. After swearing, she turned and left. Zhang Deyan chased her to the road and stopped her. Xiaojin pushed her to the ground and drove away. Of course, there is another reason behind why it was so noisy that day. That’s why Yunzike wanted to expel two people … …”
