Why did Feng Xuan burn bonds after Meng Changjun wrote classical Chinese?

Let's start with "The city is only for Xue". People in this place owe a lot of debts, many of which were owed in the past, and it is not easy to collect them. Feng Xuan took this opportunity to become a volunteer. Instead of collecting debts, he forgave their debts under the guise of orders, and burned the bonds in front of Xue's people, who must have shouted "Long live". This matter is indeed for the benefit of the people, but from a deeper analysis, it is nothing more than a reward for Meng Changjun's kindness to meet him because he has fish to eat and a car to sit on. It's a trick derived from the "imperial thought". Can't "righteousness" be bought? If righteousness can be bought, aren't those rich people in our lives the most righteous? But this is not the case. If we do not consider from the standpoint of the people, but from the perspective of safeguarding the interests of the small circle, this is effective, but it is also limited. Besides, if it weren't for your "loyalty to Xue", would it arouse the suspicion of the king of Qi and eventually lose his official position? Mr. Meng's sentence is still correct. "Say yes, Mr. Hugh."

Speaking of it, Feng Xuan is really a "great" figure. In order to make himself live a good life, he staged a wonderful "money game". He is also a shrewd "reformer" who can turn mediocrity into magic. However, he succeeded because he was able to "get along with Meng Changjun for decades without any trouble" and became a senior official, making contributions to the country, while Feng Xuan himself lived a happy life. It can be seen that all this is actually a conspiracy of Feng Xuan. He bought "righteousness" for Meng Changjun not so much for Meng Changjun as for his better life.
