The repayment date of CITIC Bank's credit card is18th after the billing date, and your billing date is 5th, so the repayment date is 23rd. The repayment amount of this month before the billing date does not include the amount after the billing date.
That is to say, 1699 yuan brushed on the 6th is not included in the April bill, so it is not necessary to repay this amount on the April repayment date, but in May.
