The administrative post level of national public officials at the official level is the most basic leadership level. National ministerial-level organs are divided into bureau-level and county-level organs. Local governments, provinces and autonomous regions have prefecture-level, county-level and township (street) levels, among which township (street) level and state organ level are equivalent units.

At the same time, the management departments of some enterprises are also set according to the titles of departments and departments, but they do not correspond to the corresponding administrative levels and have nothing to do with the treatment of corresponding positions in state organs or government departments.

In some organs (departments with higher administrative levels), staff who do not hold leadership positions enjoy official treatment according to administrative levels, and are usually appointed as chief clerks (or deputy chief clerks).
