How does the school pay the social security card?

First, universities now buy cooperative medical care for local urban residents.

1. This social security card can only be used during hospitalization.

Show it to the hospital when you are in hospital and register it. When you leave the hospital, you will be compensated. You just have to bear your share.

Second, urban cooperative medical care can generally be reimbursed by about 30%.

You don't have to pay for it. This kind of cooperative medical care is paid for one year and guaranteed for one year, and the school collects it uniformly. A year/kloc-more than 0/00.

Because I am a college student, it has nothing to do with where my hukou is.
