2. Story: Zeng Shen killed a pig

Zeng Shen was a famous thinker and Confucian in Lu at the end of the Spring and Autumn Period, and was one of the 72 sages of Confucius' protege. He is knowledgeable and versatile, and attaches great importance to self-cultivation and moral integrity. Once, his wife had to go to the market on business, and the young children clamored to go. Zeng Shen's wife didn't want to take the children, so she said to him, "You have fun at home. When mom comes back, she will kill cook the meat, the pig at home, and give it to you." Hearing this, the child was very happy and stopped clamoring to go to the market. This was meant to be a joke for the children, but after that, Zeng Shen's wife forgot. Unexpectedly, Zeng Shen really killed a pig at home. When his wife saw that Zeng Shen had killed the pig, she said, "I didn't say that I would kill the pig and burn the meat for him until I came back from the market. How can you take it seriously?" Zeng Shen said: "Children can't be deceived. Children are young and don't understand the world, so they have to learn from others, especially their parents. Today you cheat the child and defile his mind, tomorrow the child will cheat you and others; Today, you break your word in front of your children, and tomorrow your children will no longer trust you. See how harmful this is. "
