Yes, but not all departments are on duty. All kinds of policemen in public security organs are on duty 24 hours a day, and leaders on duty are always on call every day. However, there are exceptions. The household registration and entry-exit departments of public security organs are administrative, and they are closed on Saturdays, Sundays and legal holidays.

The police belong to civil servants, so they all have weekends and various legal holidays. In addition, according to the working age, there is annual leave, which is paid vacation. Of course, police work is quite special, and sometimes it is necessary to work at night or work overtime, which is calculated according to national laws.

"Public security" refers to the people's police in a broad sense, which can be divided into four categories: public security police managed by public security departments (that is, "public security" in a narrow sense, including public security police, household registration police, criminal police, traffic police, etc. ), the national security police managed by the national security department, the judicial police of the reform-through-labour department, the judicial police of the courts and procuratorates, and the anti-smuggling police managed by the customs.
