Lu's Spring and Autumn Annals recorded the story of Confucius and his two disciples and Zi Gong. Lutz saved a drowning man, and the rescued man gave Lutz a cow to show his gratitude. Lutz is closed. Confucius commented on the incident of saving a cow: Lu people like to save people from danger from now on. Coincidentally, another student of Confucius, Zi Gong, was rewarded by the government for redeeming a slave, but he refused, thinking it immoral to do good in return. Confucius commented that no one in Lu would be willing to do such a good deed of atonement for others. "Luz was persuaded, Zigong was modest and stopped being a good person."

Confucius' point of view on human studies, he said: "People never tire of taking what is righteous." In other words, as long as it conforms to morality, people will not feel disgusted and disgusted with what they deserve. Lv Chunqiu Tea Micro records that Luz saved a drowning man, and he brought a cow as a thank-you gift, which Luz accepted calmly. Confucius praised Luz's practice and said: From now on, the people of Luz will scramble to save the victims. This story is a true portrayal of Confucius' recognition and maintenance of the right to legitimate interests.

The story goes something like this:

According to the law of Lu, the people of Lu are the slaves of the princes, and those who can redeem them will take money from the government. Zi Gong redeemed the Lu people from the princes, and he didn't take their gold with him when he came. Confucius said, "It was a mistake. Since then, Lu people have never redeemed others. " If you take the money, it won't hurt the bank. If you don't take the money, you won't be saved. "Lutz saves drowning people. People worship them with cows, but Lutz suffers greatly. Confucius said, "Lu people will save drowning people. "Confucius saw it in detail and saw it far.

The other one is like this: Luz saved his life and the cow thanked him. Confucius said: Lu will be good at saving people from worries. Zigong redeemed people, and did not accept government gold. Confucius said: Lu will no longer redeem others. Lutz convinced people with virtue, and Zi Gong told him to stop being a good person.
