Why can't I use social security card in outpatient clinic of Zhaoqing Hospital?

It can be used in hospitals or outpatient clinics with designated medical insurance qualifications, but when it is used for the first time every year, you need to choose a designated hospital first. Within a medical year, you must see a doctor in this hospital to be reimbursed, and it is not reimbursed in other medical institutions. You can choose another designated hospital in the second year. As for the designated medical pharmacies, no matter which one in Zhaoqing, you can buy medicine by swiping your card.
