The grace period of Ping An Bank's credit card repayment will be automatically extended. Ping An Bank's credit card generally has a three-day grace period after the repayment date, and repayment within the grace period is regarded as timely repayment. However, we should pay attention to the following issues:

1. If it is paid off in full, no cost will be incurred;

2. If the repayment amount is less than the minimum repayment amount stipulated by the bank, it will be deemed overdue, with interest of 0.05%, and the unpaid part of the minimum repayment amount will be subject to a 5% late fee;

3. If the repayment amount is greater than or equal to the minimum repayment amount and less than the full repayment amount, interest will be paid at 0.05%.

However, repayment beyond the grace period is considered overdue: interest is 0.05%, and there is a late fee.

I hope my answer can help you. You can also call the customer service phone of the bank for consultation.
