I heard that Nanjing Library and China's Second Historical Archives have changed to refer to the civil service system, so how do you want to enter the exam?

Both places belong to fully funded institutions. If you have a very hard door, you may fall in.

Civil servants "must take the exam", and institutions in China implement the "appointment system", so it is enough for someone to hire you, so you must find a hard background.

Reference to the civil service system refers to the rank and salary.
