Liu Kuan has a simple personality and likes drinking, but he doesn't like washing his hands and taking a bath. Therefore, Shi Jing specially invented a proverb. Liu Kuan's subordinates will not be punished as long as they are drunk and make mistakes. Once he sat with a guest and asked his old servant to go to the market to buy wine. It was a long time before the old servant came home drunk. The guest couldn't help cursing: "beast." Liu Kuan soon sent someone to visit the old servant, suspecting that he would commit suicide. He said to the people around him, "This man called him an animal. What could be more insulting? So I am afraid that he will commit suicide. "
