At that time, the monarch himself and those very small officials were under the supervision of these people. At that time, officials of the Ming Dynasty were nervous when they saw these censors, fearing that they would investigate themselves. According to Zhu Yuanzhang's suspicious character at that time, Yushitai would not be allowed to operate independently. So when he set up this department, he also set up another department called the Supervision Institute. The mutual supervision between the two departments has played a very good role in restricting. According to historical records, these censors hope to be honest and clean. They will do practical things by the rules. A bad word, they will not be flexible, but will only accept death. But it is precisely because of their personalities that they can better serve the whole country. If someone makes a mistake, no matter who it is, it will be severely punished by law. At that time, these censors even objected when they found that the monarch had done something wrong. Even Zhu Yuanzhang at that time did not think that these suggestions did not give himself face at all.
