Story 1: Luz saved a child, and his father gave him a cow. Lutz accepted. Some people say that Lutz's good deeds should be rewarded, but Confucius praised him and said: In this way, more people will do good deeds in the future. Story 2: During the Spring and Autumn Period, there was a law in the State of Lu: When people from the State of Lu traveled to other countries and saw that people from the State of Lu became slaves, they could redeem them with their own money first, and then go to the government for reimbursement after returning to the State of Lu. The government pays the ransom with the money from the national treasury and gives certain rewards. Zi Gong, a student of Confucius, went abroad and happened to meet a Lunu there, so he paid to redeem him. After returning home, Zigong didn't make public, nor did he go to the government to reimburse the ransom paid. The person who was redeemed told everyone about the situation, and people praised Zi Gong for his integrity and noble personality. For a time, all the streets and alleys regarded it as a beautiful talk. When Confucius learned about it, he not only didn't praise Zi Gong, but also severely criticized him: accusing him of making a mistake that violated the social avenue, but only ignoring the avenue for small righteousness. Confucius pointed out that Zi Gong was praised as virtuous because he didn't go to the government to reimburse the ransom. Then others go abroad to see the Lu people become slaves, and they will hesitate to pay for his redemption. Because the money is used to redeem him and then go to the government for reimbursement to receive the prize, people will say that they are not upright and noble; If you don't go to the government for reimbursement, who will make up for your own losses? As a result, it is better to have more than one thing, so we have to pretend not to see it. Objectively speaking, Zi Gong's behavior prevented more Lu people who were slaves in foreign countries from being redeemed.
