Is there a direct connection between rural insurance and social security card medical care?

The rural insurance at home is limited to seeing a doctor at home, and you can go to the village for reimbursement with the invoice. If you are in a different place, that is, where you work, you can't reimburse your hometown's medical insurance, but you can only use it to apply for a social security card. On the other hand, to see a doctor at home, the social security card needs to be signed back, otherwise it cannot be reimbursed.
