Why did Master Poplar go to prison?

Drunk driving. In the TV series "The Honor of the Police", the owner of poplar is Cao Jianjun. After Cao Jianjun was finally sent to the traffic police for drunk driving, he got hot-headed and drove away for fear of being punished. In this way, Wang Shouyi, who came to deal with the problem, was greatly annoyed and said directly: Cao Jianjun is seeking death. Paper can't cover the fire, and eventually it goes to jail. Things about Cao Jianjun always get around.
