There was a man named Feng Xuan in the State of Qi. His family is poor and it is difficult to support himself. He asked Meng Changjun to bring him food. Meng Changjun asked, "Does your husband have any hobbies?" Feng Xuan said, "No." Meng Changjun asked again, "Does Mr. Wang have any special skills?" He said, "No." Meng Changjun accepted him with a smile: "All right." People around Meng Changjun gave him bread and water because his master didn't care much about Feng Xuan. Not long after living, Feng Xuan leaned against the pillar and sang with a sword: "Long sword, let's go home, there is no fish for dinner." Tell Meng Changjun about it. Meng Changjun said: "Give him the treatment of ordinary guests and let him eat fish." Not long after he lived, Feng Xuan played with his sword again and sang, "Long sword, let's go home. We go out without a car. " Meng Changjun said: "Give him a car and treat him as a passenger." So Feng Xuan drove with a sword and boasted to their friends, "Meng Changjun respects me as a guest." After a while, Feng Xuan flicked his sword again and sang, "Long sword, let's go home. We can't afford to support a family." People around him don't like him and think he is insatiable. Meng Changjun asked, "Does Mr. Feng have parents?" Left and right replied: "There is an old mother." Meng Changjun supported his family and kept his mother away from poverty. Feng Xuan never sang sad songs again.

Later, Meng Changjun posted a notice and asked the diners, "Who is familiar with accounting and can help me collect debts from Snow Emperor?" The name of the Feng Xuan department says, "I can." Meng Changjun looked very surprised and asked his entourage, "Who is this?" People replied, "it's the man who sings' long sword, let's go home'." Meng Changjun smiled and said, "He is really talented. I really feel sorry for him. I haven't seen him yet. " So he invited him to meet him and apologized: "Tian Wen is bored with trivial matters every day, exhausted physically and mentally, confused by sorrow, born weak and clumsy, but neglected her husband because of government affairs." Fortunately, Mr. Wang doesn't blame me. Will Mr. Wang go to Sidi to help me collect debts? Feng Xuan said, "I am willing to work hard." . "So Meng Changjun prepared chariots and horses for him, and let him go with the contract. When he left, Feng Xuan asked, "What shall I buy after collecting the debt?" Meng Changjun replied, "It's up to you, sir. Buy what my family lacks. "

He hurried to Xue's place and sent for all those who were in debt to audit the accounts. After all the inspections, Feng Xuan stood up, rewarded these people's debts in the name of Meng Changjun, and burned the bond documents. Long live the gratitude of the people.

Feng Xuan returned to Linzi, the capital of Qi, and asked for an audience with Meng Changjun early in the morning. Meng Changjun was surprised that he came back so soon, so he got dressed. When he saw him, he said, "Have you finished collecting the debt? Why are you back so soon? " Feng Xuan replied: "It's all collected." "What did Sir buy me?" Feng Xuan said, "Your Highness once said,' Buy some things that are lacking at home'. I thought to myself that your highness's palace is full of jewels, dogs, horses and beautiful women. The only thing missing in your highness's family is benevolence and righteousness, so I took the initiative to buy it for your highness. " Meng Changjun said, "How did you buy Renyi?" Feng Xuan replied, "Your Highness only has a small piece of snow land. Instead of sympathizing with Xue's children, he squeezed benefits from them like a businessman. For the sake of the monarch, I secretly conveyed his royal highness's orders, gave them all the debts and burned all the bonds. People shouted long live. This is the kindness I bought for your highness! " Meng Changjun said unhappily, "I see, sir. Please step down and have a rest. "

A year later, the king of Qi said to Meng Changjun, "I dare not use the old minister of my late king as my minister." Back to Xue, it's less than a hundred miles from here. The local people greeted Meng Changjun by the roadside. Meng Changjun turned to Feng Xuan and said, "I just saw the Yijing that Mr. Wang bought for me today."
