What is the pyramid structure of the chinese communist party?

Explanation:

to join, applicants need the backing of existing members and to undergo exhaustive checks and examination by their local party branch. They then face a year's probation, again involving assessments and training.

The party has a pyramid structure resting on millions of local-level party organisations across the country and reaching all the way up to the highest decision-making bodies in Beijing.

In theory, the top of the pyramid is the National Party Congress, which is convened once every five years and brings together more than 2,000 delegates from party organisations across the country.

The congress' main function is to "elect" a central committee of about 200 full members and 150 lower-ranking or "alternate" members", though in fact almost all of these people are approved in advance.

In turn, the central committee's main job is to elect a new politburo and its smaller, standing committee, where real decision-making powers lie.
