The national civil service examination, referred to as the "national examination", refers to the civil service examination of the central and state organs. It is a way for national ministries, departments and general administration to recruit staff in central and state organs. The recruitment conditions are relatively strict, generally requiring full-time undergraduate graduates and previous graduates, and some positions require master students and CET-4 and CET-2. The time is relatively fixed, generally concentrated in 10- 1 1 every year.
