Are the employees of the Social Security Bureau national civil servants?

The employees of the Social Security Bureau are not national civil servants, but institutions.

Civil servants are the staff of state organs, generally have the power of law enforcement, and are all departments that exercise state power.

Institutions are state institutions and do not have state power. They are only affiliated institutions of some countries, such as research institutes and public schools. Institutions have three forms of wages:

One is to fully refer to the treatment of civil servants, and the state finances fully allocate funds, like the Forestry Bureau.

One is the difference, the state gives you a percentage point, and then your own unit gives you a percentage point, like a public hospital.

Another is that the state only cares about the establishment, regardless of wages, only gives policies, not money, like some museums.
