Which should be used first for hospital insurance and advance payment?

Advance payment. Pay a sum of money in advance when you are in hospital, and you can't deduct it from the medical insurance card. Pay in advance when you are in hospital. If the medical insurance card is also paid to the inpatient department of the hospital, the hospital will ask the inpatients to pay different amounts of money according to their illness, so as to deduct the expenses in their accounts except medical insurance.
