Story: Zeng Shen Killed the Pig

Zeng Shen, a famous thinker and Confucianist in the State of Lu in the late Spring and Autumn Period, was one of the seventy-two sages among the disciples of Confucius. He is erudite and talented, and pays great attention to self-cultivation and high moral character. Once, his wife had to go to the market to do errands, and the young children were clamoring to go. Zeng Shen's wife didn't want to take her child there, so she said to him, "You have fun at home, and when mother comes back, I will kill the pigs at home and cook meat for you to eat." After hearing this, the child was very happy and stopped clamoring to go. It's market time. This was meant to coax the children, but Zeng Shen’s wife forgot about it. Unexpectedly, Zeng Shen actually killed a pig at home. When his wife saw Zeng Shen killing the pig, she said, "I just wanted to let the child wait at home with peace of mind, so I said I would kill the pig and roast the meat for him to eat when I came back from the market. How could you take it seriously?" Zeng Shen said: "Children cannot be deceived. Children are young and do not understand worldly affairs. They have to learn from others, especially their parents as role models in life. Today you have deceived your child and soiled his heart. Tomorrow the child will deceive you and deceive. Others: If you break your promise in front of your children today, your children will no longer trust you tomorrow. You see how harmful this is."
