Generally speaking, their relationship is as follows:

Generally speaking, among these four departments, the Security Department is directly superior and can directly supervise the heads of the other three departments. However, police officers in judicial police stations and public security police stations are usually not directly commanded, but managed by the general police station. Therefore, the general police station is also the small head of the other two bureaus, that is, the "direct superior" of the Public Security Bureau and the Judicial Bureau, and it is a department lower than the "Security Department".
