Are plainclothes policemen, cyber policemen and traffic policemen all civil servants? Do you have a contract?

The police can generally be divided into administrative police and contract police according to whether they are in the ranks or not. The general society usually calls them official policemen and assistant policemen. Although the administrative law enforcement powers of the two are slightly different, they both belong to the staff of the Public Security Bureau and the official police. Network police are all admitted through the unified examination of civil servants, which belongs to the establishment of civil servants.

I don't understand other positions of contract system. The contract police here are generally some foreign auxiliary police, and there are a small number of back-office civilian posts, such as the household registration police at the police station and the counter in the registration hall.

I hope it helps you.
