I would like to ask the institutions to enroll students separately (non-civil servants), where is the written test marking? Does the recruiting unit read the papers by itself?

The human resources department has the final say in marking written papers, and there are specialized marking institutions in the city and the province.

Not self-bidding (self-bidding is illegal recruitment)

Not a civil servant, not even a unified recruitment examination.

Officials in government departments are called civil servants, such as organization department, personnel department, finance bureau and other authoritative departments.

Those who assist government officials are called institutions, such as science and technology bureau, seismological bureau, agricultural machinery and other non-functional departments.
