Wuwei City is a prefecture-level city, and its administrative level is the main hall level (bureau level). Municipal Public Security Bureau (director level) is one of the constituent departments of the municipal government.

Gao Kaishan is the deputy director of Wuwei Public Security Bureau and concurrently the director of Liangzhou District Bureau. So his administrative level is a place class.

PS: Public security organs often have senior cadres. For example, the director of the provincial public security department is the secretary of the provincial political and legal Committee or the deputy governor, the director of the municipal public security bureau is the deputy mayor, and the director of the same branch is the deputy director of the municipal bureau. After the cadres are fully staffed, the administrative level of the post itself will not change. For example, the level of the post of director of the Public Security Bureau in Liangzhou District is the department level, and the administrative level of the post of deputy director will not become the department level, but it will not change.
