Credit card waiver of CCB cannot be extended. If the cardholder wants to choose to postpone the reduced time, it is impossible. When the cardholder triggers the bank's risk control system, the system will immediately reduce the amount after making a judgment, and the cardholder will not reflect it. If the cardholder wants to choose to postpone repayment, he should either pay the minimum repayment amount and move the bill to next month, or negotiate repayment after it is overdue for 3 months. However, the chances of CCB agreeing to negotiate repayment are relatively small.
