Institutions are mainly responsible for technical affairs or public affairs, such as schools, hospitals, libraries and so on. In some places, some secondary bureaus of government agencies are also institutions, especially at the city and county level, such as the Highway Bureau under the Transportation Bureau, the Urban Management Bureau under the Construction Committee and the Agricultural Machinery Bureau under the Agriculture Bureau. Although these units are also called bureaus, they are all institutions, and the staff inside are not civil servants. However, every place is different. In some places, these units are classified as institutions managed by civil servants, and in some places they are classified as general institutions.

Referring to the institutions managed by civil servants, the nature of work of these institutions is basically the same as that of civil servants. Because it can't be directly classified as a party and government organ, according to the name of the institution managed by civil servants, the treatment of the institution managed by civil servants is the same as that of civil servants. Some units are fully funded by the government, and some units are solved by financial allocation and self-raised funds.

There is no uniform standard for the accurate division of civil service units, organs and institutions with reference to civil service management, which varies from place to place. Some units are civil servants in some areas, but some may be reference or general institutions. So you'd better consult the relevant departments.
