All officials, from the deployment of special envoys to the provincial magistrate, are within their assessment scope. The money and grain files of local warehouses are all patrolled according to suggestions. It can even be "big things decide big things, small things decide big things", that is, "whoever says it will do it!" They are not only preservatives of the dynasty, but also "eyes" and "ears" of the country. Three centuries of prosperity in the Ming Dynasty, more or less serious and responsible imperial patrol, is the unsung hero behind it.

There was no such official position in ancient times, but according to this official position, it can be judged that this is actually a supervisory suggestion, and "Eight Houses Patrol Press" is just a folk name. In novels and operas of the Ming and Qing Dynasties, it is also called "Eight Houses Patrol Press", which is endowed with high authority. Historically, the powers of the eight governments to patrol were indeed great enough. They toured various places on behalf of the emperor and exercised their supervisory power. When local officials saw them, they were really walking on thin ice.

Inspectors such as "Eight Houses Patrol Press" are usually at a lower level. They believe that although officials with lower positions and younger ages may have weaker ability to find and analyze problems, they may have less concerns when dealing with problems, so they may be relatively fair when dealing with problems, which is conducive to the cultivation, training and education of young officials' ethics. The purpose of taking the post of outstanding young people is to let those who have just entered the officialdom and have not been baptized and degraded by the officialdom examine them and avoid the interference of human feelings and utilitarianism. Later, it was also called the supervision suggestion, which was available in the Sui Dynasty. Until the Qing Dynasty, the ranks were lower, with eight grades in Sui and Tang Dynasties, seven grades in Song Dynasty, seven grades in Ming Dynasty and five grades in Qing Dynasty.

However, although he was able to solve the case, he was involved in a lawsuit. It turned out that Chang Wei, the son of the navy's prefect, saw Qin Xiaolian, the newly married bride of Qi's family, as beautiful as flowers and pure as jade, similar to the current Central Leading Group for Inspection Work, and went to various places to inspect corruption, official dereliction of duty and eliminate evil. However, it was set up temporarily in ancient times, and the Central Inspection Team is a permanent institution that constantly monitors injustice in various places. So he found an opportunity to strengthen her. After the story was revealed, Chang Wei simply killed all the Qi family 13 people.
