During the Ming Dynasty, the imperial court would send a Qipin official to the local area to serve as an inspector of the imperial history, equivalent to the modern cadres at the level of the department, who were mainly responsible for monitoring whether the local officials had committed crimes such as corruption, fraud, cruelty to the people, and private use of public property, which was equivalent to the modern inspection team sent to the local area.
Once the inspector Yushi found that the official had committed illegal acts, he could immediately report it to the emperor, and no matter how high the other party's rank was, the emperor would send the inspection team to investigate at the first time.
When major accidents occur in places, such as the death of many people, the breaking of the Yellow River embankment, the mob uprising, the collapse of mines, and the low GDP, inspectors will be sent to investigate the causes.
Although these people are of low rank, they have great power, and even if they are high-ranking officials at the provincial and ministerial levels, they must be provided by their grandfathers. When they encounter incorruptibility, they can only cry out in secret.
The "History of Ming" records that there was a member of the inspection team named Wang Yi, who was sent to Shaanxi to inspect and found that the local bullies had embezzled the property of the people, so he told the local officials.
The local officials did not dare to be sloppy, and immediately dealt with it, and returned the property to the people from the bullies.
When Wang Yi inspected Henan, there was a relative of the emperor who recruited very outlaws, specializing in hitting the family and robbing bad things, and no one dared to take care of them. After Wang Yi arrived in Henan, he quickly investigated the matter and reported it to the imperial court, which quickly seized the man's title and put him in prison.
