Because when seeing a doctor, the doctor will record the patient's information on the card, such as previous medical treatment and illness. If you mix it with others, it may bring inconvenience to your future medical treatment (you have never had a disease before, but the person who used your card recorded it for you, and the doctor will consider your previous medical history next time); There is also the issue of reimbursement, because it is your card, so the drug list and hospitalization information are in your name. If you don't buy medical insurance, if your father has it, you can't reimburse it.
You can go to Huaxi Hospital to get a temporary medical card for your father, and then make an appointment to register.
