Later, he took out a proclamation and asked his public: "Who knows accounting, can I collect debts?" Feng Xuan signed it: "Yes." Meng Changjun thought this man was strange and asked, "Who is this?" People around said, "The one who sang' The Return of Longchuan'." Meng Changjun smiled and said, "This guest is really talented. I feel sorry for him. I have never seen him! " Immediately send someone to invite Feng Xuan to see him and apologize: "I am very tired of business, and my heart is troubled by sadness;" And (I) am weak and incompetent, and I have sinned against you by indulging in state affairs all day. You are shameless, and you want to collect debts from your schoolmate for me? " Feng Xuan replied, "Yes. "So I packed my car, packed my things, loaded my debts and set off. Take leave and say, "I've collected all my debts. What can I buy from the debt? " Meng Changjun said, "Look at what my family lacks. Let's get to Xue's place and order someone to call out all the debtors to audit the accounts. "。 After all the debts were verified, he stood up, faked (Meng Changjun's) orders, handed over the debts to the people, burned the bonds, and the people shouted "Long live". Feng Xuan has been driving (without delay) to Linzi and Qidu, and asked to see Meng Changjun in the morning. Meng Changjun was surprised that Feng Xuan came back so soon. He put on his clothes and hat to meet him and asked, "Have all the debts been collected? Why are you back so soon? " Feng Xuan said, "Everything has been collected." "What did you buy back? Feng Xuan said, "You said,' Look at what my family lacks'. I think privately that your palace will be rich, the stable outside will be rich, the place where Chen Fang's property and concubines stand under the hall will be rich, and the beautiful women will be rich. What your family lacks is benevolence and righteousness! I bought you righteousness in private. " Meng Changjun asked, "How can I buy righteousness?" He said: "Now that you have a small Xuedi, you don't appease (the people). You regard the people in Xuedi as your own son, and you take advantage of the people in Xuedi in the way of businessmen. I forged your order in private, gave the debt to all the people, and burned the deed, and the people cheered' Long live'. This is the way I use to buy you righteousness. Meng Changjun said unhappily, "Oh, forget it, sir." . On the first anniversary, King Qi Zhuo said to Meng Changjun, "I dare not let my late king's courtiers be my courtiers." Had to give his fief to xue. There are hundreds of miles away from Xue, and Xue's people are on the way to meet them. Meng Changjun looked back at Feng Xuan: "I just saw the morality of buying righteousness for me today. "
