Yongzheng asked the minister a joke.

No matter which dynasty, corruption will happen. During the Yongzheng period, officials were asked whether they were greedy for money or not, and they also told the truth. Because officials know that Yongzheng is testing him, in fact, Yongzheng is like a mirror in his heart. Which official is not greedy? Yongzheng only warned officials to be less greedy, and the insatiable court would not allow it. Being an official in the imperial court will inevitably lead to corruption, which is inevitable at any time. As long as corrupt officials can do more work for the court, the court will not care if they earn extra money. Yongzheng also attached great importance to these corrupt things. Yongzheng knew that corruption was unclean and could only suppress the corruption of these officials. When it was suggested that officials had local greed, all officials in the imperial court were afraid to speak out. Only one county magistrate named Shen dared to speak out. He advised Yongzheng not to open a hole for officials' corruption, and Yong Zhengdi asked him if he had any corruption. The magistrate Shen did not dare to tell lies to Yongzheng. He said he didn't want to be corrupt, but the old and the young at home forced him to be corrupt. I have to say that this official is very clever. He knew that cheating the emperor was more serious than corruption, so he dared not cheat the emperor. Yongzheng didn't punish him because of his loyalty. Yong Zhengdi also knows that the whole court is corrupt, and the more powerful people are, the more corrupt they are. This kind of thing can't be cured. Since people in the imperial court are used to do things for themselves, they should turn a blind eye to some harmless things. Yongzheng wouldn't care about their corruption as long as they could ensure that there was no big trouble in the Qing Dynasty. On the contrary, corrupt people will be willing to do things for themselves. This is also the genius of Yongzheng. Yongzheng knows how to manage state affairs, and only by being moderate can he manage the Qing Dynasty well.
