Why is my place of enrollment the university?

Because you paid your current year's premium while attending college, the place of enrollment will be your college location. You can contact your local social security office directly to inquire about this.

Basic medical insurance is a social insurance system set up to compensate workers for financial losses caused by the risk of illness. Through the contributions of employers and individuals, a medical insurance fund is established, and after participants incur medical expenses for sick visits, the medical insurance agency will give them some financial compensation to avoid or mitigate the economic risks that workers incur due to illness, treatment, and so on.

Origin of the implementation of China's medical insurance system:

In December 1998, the State Council issued the Decision on the Establishment of a Basic Medical Insurance System for Urban Workers (Guo Fa No. 44), which called for the establishment of the basic medical insurance system for urban workers as the core of a multi-level medical insurance system. The Decision states that the main task of the reform of the medical insurance system is to establish a basic medical insurance system for urban workers, i.e., to adapt to the socialist market economic system, and to set up a social medical insurance system that protects the basic medical needs of workers according to the affordability of finances, enterprises and individuals.

The principles for the establishment of a basic medical insurance system for urban workers are: the level of basic medical insurance should be commensurate with the level of development of productive forces at the primary stage of socialism; all urban employers and their workers should participate in basic medical insurance, and local management should be carried out; the costs of basic medical insurance should be borne by the employer and the worker***; the basic medical insurance fund should be a combination of a social coordinating system and individual accounts. The basic medical insurance fund is a combination of social coordination and individual accounts.
