There is such a story in the story "The Warring States Policy": "Ke" tells the story of Shi Hao of Qi during the Warring States Period. There are thousands of diners under his door, and one of them is Feng Xuan. In Meng Changjun's home, Feng Xuan once sang with a sword: "When the shovel comes back, there is no fish to eat, no car to go out, no home to think about", so Feng Xuan has fish to eat and a car to go out. One day, Meng Changjun sent a notice and asked the guests in the house: "Who is familiar with accounting and financial management, can go to the snow to help me collect debts?" Feng Xuan wrote in the notice: "I can". So Meng Changjun sent Feng Xuan to collect debts. When saying goodbye, Feng Xuan asked, "What can I buy for all the debts?" Meng Changjun said, "I will buy whatever is missing at home." Feng Xuan drove a carriage to Xuecheng and sent officials to call all those who should pay their debts to check the contract. After checking the loan agreement, Feng Xuan lied about Meng Changjun's orders, gave the loan to the people and burned the loan agreement. People cheered in unison, long live. Feng Xuan returned to the capital of Qi without stopping, and went to see Meng Changjun early in the morning. Meng Changjun was surprised that he came back so soon, so he put on his coat and hat to meet him and asked, "Have you collected all your debts?"? How did you come back so soon? " Feng Xuan replied, "All of them." Meng Changjun asked again, "What did you buy with it?" Feng Xuan said, "You said,' You can buy anything that your family lacks'. I see your house is full of treasures, good dogs and horses, barns and beautiful women in the hall. What your family lacked was righteousness, so I bought it for you. " Meng Changjun asked: "How to buy righteousness?" Feng Xuan said, "Now you only have a small snowy area, but you can't take care of the people there. On the contrary, you charge people interest by means of businessmen. I secretly dispersed your order and burned the loan contract. People cheered in unison. This is the' righteousness' I bought for you. Meng Changjun said unhappily, "Oh, forget it, sir!" A year later, the king of Qi Min said to Meng Changjun, "I dare not take my late king's courtiers as my courtiers." Meng Changjun had to return to the fief where Xue Cheng lived. Going to a place one hundred miles away from Xuecheng, the people helped the old and the young, and met Meng Changjun on the road all day. Meng Changjun turned to Feng Xuan and said, "I saw the charity sale that Mr. Tian Wen bought for me today. "Renyi is not as tangible as money or goods, so Meng Changjun is very dissatisfied with Feng Xuan's acquisition of Renyi. When Meng Changjun was exiled by the King of Qi and returned to Xuecheng, he realized that what he had lost in the past had been doubled today. It' s really' righteousness is more important than profit'! A long time ago, Renyi Hutong was now two adjacent places. However, due to the border dispute, one of them is an official in Beijing. His family wrote to him to explain that there was a dispute with his neighbor and he wanted to solve it by himself. This official is honest and open-minded, and will not bully others for private affairs at home. He attached a poem to his letter to his family, which showed his attitude: it is a wall thousands of miles away, so why visit it? The Great Wall of Wan Li has made great contributions through the ages, and Qin Shihuang is absent. After receiving this poem at home, everyone understood the opinions of the person in charge who was an official abroad and acted accordingly. Not only did he stop arguing with each other, but he also voluntarily gave up three feet of land. As the saying goes, there are not enough competitors, so there are more competitors. As soon as this family gave in, the other family was moved. As soon as the family members discuss it, they should put humility and kindness first and take the initiative to give up a place three feet wide. So the two families gave up six feet wide. What shall we do? There is a lack of a north-south passage here, so we built an alley. I don't know who suggested naming the alley with the word "benevolence". People have been calling it that for hundreds of years until today.
