The principal's administrative level is the official level, and the deputy county level is the school. If it is a primary school directly under the education bureau of a prefecture-level city, it is generally a department-level organizational system. The middle schools directly under the Municipal Education Bureau can implement the official-level system and the deputy-level system, or they can not implement the administrative system. Therefore, the administrative level of district-level middle school principals is at most equivalent to that of primary school principals directly under the education bureau of prefecture-level cities, and most of them are lower than those directly under the education bureau of prefecture-level cities.
