China Construction Bank has paid the minimum credit card. Why should SMS be paid in full?

You should have received a repayment reminder message from CCB. Credit cards have a fixed billing date every month, and 20 days after the billing date is the final repayment date. Before the final repayment date, consumers will be repaid in full according to the bill amount and enjoy the interest-free period. If you don't repay in full and on time, consumers won't enjoy the interest-free period, and the bank will charge interest in full at the rate of five ten thousandths per day from the date when your consumption is recorded.

If you have paid the minimum repayment amount during this period, you can not continue to repay, and your personal credit will not be affected, but your consumption does not enjoy the interest-free period. If you pay off all the remaining amount within 2 days after receiving the text message, then the consumption of this bill still enjoys an interest-free period without interest.
