1. Repay on time on the repayment date to avoid default interest and compound interest. The repayment date is 18 days after the bill date.

2. Credit card withdrawal will charge a certain fee and generate interest, so you should repay as soon as possible after withdrawal.

3. Pay attention to the annual fee of the credit card. Most CCB credit cards are exempt from annual fees by swiping their cards.

4. Bookkeeping dates can be selected: 5th, 7th, 10, 13, 15, 17, 20th and 25th of each month. You can reasonably choose the accounting date according to your actual situation, and the accounting date can be changed once every six months.
