Luxury sports cars, rich children, Zhejiang University graduates, people killed by racing cars, and many eye-catching factors come together, which has aroused widespread and enthusiastic attention from the society to the Hangzhou racing case. The initial hasty appraisal by the local traffic police department finally turned this concern into a network storm. A few days ago, the families of the victims accepted the appraisal report of the public security organs, and the perpetrators were arrested for traffic accidents. Why traffic accidents become public events is interpreted from all aspects. Obviously, the reason why this case can attract so much attention and easily touch the sensitive nerves of the public is not just a simple traffic safety or the education of the rich second generation. As some commentators have pointed out, the drag racing case has aroused people's strong concern about social fairness and justice and exposed the anxiety of the general public about their own safety. In the author's view, the group psychology and emotions between different classes reflected by this anxiety deserve everyone who cares about the social harmony and progress in China to be alert. In a sense, the Hangzhou drag racing case is of specimen significance to our time. Undeniably, after years of rapid economic development, a class that gets rich first has emerged in our society. Although these people have not yet formed a unified wealth ethics, code of conduct and value orientation, it is obvious that some of them have a low image in the eyes of the general public. Their conspicuous consumption of hundreds of thousands and millions often makes the working class with hundreds of thousands of mortgages stunned. In addition, many people's wealth is not so sunny and transparent, and there are many gray areas on their way to get rich first, which makes the general public feel a strong sense of injustice. Among them, luxury cars are undoubtedly a label of the first rich class, and almost every accident has become the focus of the moment. In the drag racing case in Hangzhou, the media intentionally or unintentionally emphasized the different identities of the two sides. "A rich kid driving a sports car" and "a graduate from a famous school with a poor family and excellent academic performance" undoubtedly amplified people's cognition and emotions about this class division. Originally, the law is a * * * the same rules of the game that both the rich and the poor should abide by. However, after the motorcycle racing case, Hangzhou police did not immediately arrest the perpetrators. The uncertainty of the wording of the initial accident identification made the public daydream about the transaction of power and money and doubt the credibility of the judiciary. Among them, a friend of the perpetrator made a phone call for 40 minutes to try to reconcile, which was a particularly typical scene. It is not a strange social phenomenon that some rich and powerful people have more social resources, and many people "smooth" them when they are in trouble. However, every "reconciliation" is eroding the credibility of the last right barrier of justice. In fact, none of the above is affordable for Hu Bin. To be fair, the public and the media have overreacted to this case, but this overreaction is understandable. The lack of right relief channels, dissatisfaction with unfair distribution, and the accumulated dissatisfaction all need a channel and opportunity to release. The racing car shell is just an amplifier and a fuse. Irrational factors flashed in netizens' expressions are equally disturbing. If the rich and the grassroots have nothing in common except mutual contempt and abuse, it will lay a huge hidden danger for our society. In the final analysis, we need to bring different expressions of interests and conflicts into the track of the rule of law. Whether driving a BMW or squeezing a bus, let everyone live a dignified life and get effective judicial protection when they are infringed, which should be the proper meaning of building a harmonious society. Among them, the importance of fair justice cannot be overemphasized.
