There is a story in the Warring States Policy: The Guest 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. At home in Meng Changjun, Feng Xuan once sang with a sword: "After a long time, he came back, didn't eat fish, didn't go out by car, and missed home." So Feng Xuan ate fish, went out with a car, and his mother.

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! "

After a year, King Qi Min said to Meng Changjun, "I dare not take my former king's courtiers as my courtiers." Meng Changjun had to go back to the fief of Xuecheng to live. 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 Yijing that Mr. Tian Wen bought for me today."

People's art is not as tangible as money or things, so Meng Changjun is very unhappy that Feng Xuan bought people's art. 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'!
