The party school system is a closed system, especially the advanced training of party and government cadres, which is not accessible to anyone who wants to enter. First of all, it belongs to the internal system of a political party. There is a certain personnel screening for senior cadres and grassroots cadres who have received advanced training. Local party committees and organizational departments recommend suitable candidates to study in party schools, and party and government cadres who receive advanced training and further study are basically likely to be promoted.

It can be said that the party school is the cradle of party and government cadres and the "channel" for their career development, and both the form and the content are indispensable, at least for now.

According to the functions, tasks and nature of Party schools and administrative colleges, there are mainly three classes, namely, advanced classes, training classes and special seminars.

The main task of the refresher course is to further learn relevant theoretical knowledge and cultivate their abilities after leading cadres have held leadership positions for a certain period of time, so that their skills can be further enriched and improved to be competent for their jobs. The training target is the leading cadres of municipal management. The main task of the training course is to systematically train leading cadres and civil servants in basic theory, basic knowledge and basic ability before entering new posts, so that they can have corresponding qualifications. The training targets are leading cadres at the municipal level. In principle, the study time of all kinds of advanced classes and training classes is adjusted to one month, with four periods of spring, summer, autumn and winter every year, and each period is divided into several shifts.
