Ceng Zi is a student of Confucius. Once, Ceng Zi's wife was going to the market. Because the child was crying, Ceng Zi's wife promised to help him kill the pig when he came back. After Ceng Zi's wife came back from the market, Ceng Zi caught pigs and killed them. His wife stopped him and said, "I'm just joking with the children." Ceng Zi said, "You can't joke with children. If children are not sensible, they should learn from their parents and listen to their instructions. Now you are coaxing him, that is, teaching children to lie. " So Ceng Zi killed the pig. Ceng Zi knew that honesty and trustworthiness were the basic principles of being a man. If you don't kill the pig by mistake, the pig at home will be saved, but it will leave an indelible shadow on the mind of a pure child.
