Once a civil servant goes to a party school to study, he has a great chance of being promoted. The party school is a public institution, and its main responsibility is to train leading cadres and young and middle-aged cadres.

Party school is also a big system, which consists of central party school, provincial party school, municipal party school and county party school from top to bottom, but the relationship between them is not leadership, but business guidance.

There are more than 3,000 party schools in China, among which there are more than 2,000 party schools at the county level. The number of municipal party schools, provincial party schools and central party schools is decreasing in turn.
