CCB's credit card bills are paid out on time every month. If there is no consumption, the interest, annual fee, late fee, handling fee and over-limit fee charged by the bank according to the credit card regulations will also enter the current bill. After the bill comes out, it needs to be repaid. If there is an overpaid part in the card, it will be directly deducted, which is equivalent to repayment. These will be clearly shown on the bill. You can log on to the online bank to check the paid bills and unpaid bills, and there will be a breakdown of income and expenditure on them.
