First, the CCB savings card can be transferred to the CCB credit card, and the money can be transferred to the credit card by entering the card number of the credit card.

Second, if it is the same cardholder's savings card and credit card, you can open the agreed repayment business and bind the savings card to credit card repayment. As long as the status of the savings card is normal and the amount is sufficient, the bank will automatically deduct the money and return it to the credit card one day after the due repayment date.

Third, if online banking is opened on CCB's savings card, you can directly choose to transfer and repay on online banking. Just choose the bank to repay the loan directly.
