Zengzi killed the pig Zengzi was a student of Confucius. One time, Zeng Zi's wife was going to the market. Because the child was crying, Zeng Zi's wife promised to kill a pig for him to eat when she came back. After Zeng Zi's wife came back from market, Zeng Zi wanted to catch pigs and kill them. His wife stopped him and said, "I was just playing around with the children." Zeng Zi said, "You can't play with children. Children don't understand. Learn everything from your parents and listen to their teachings. Now if you trick him, you are teaching your child to lie." So Zengzi killed the pig. Zeng Zi’s wife deeply understood that honesty and trustworthiness, and keeping one’s word are the basic principles of life. If one makes a mistake and does not kill the pig, then the pig in the family will be saved, but it will leave an indelible shadow on the heart of a pure child.
