1. Go directly to the bank ATM machine and deposit money.
2. Go to the counter of your bank and pay back the money.
3. Use online banking, mobile banking, Alipay, Lakala, etc. to repay the money.
PS: Credit cards only belong to the credit card center, and there is no concept of belonging, same city, or different place in the traditional sense of debit cards.
As far as the card itself is concerned, there is no handling fee for repayment. (Except third-party payment platforms)
