Yes, it's safe. According to the information of China Construction Bank official website, after the credit card of CCB is overdue, it is safe to deduct 1 time a day until it is paid off. Credit cards are mainly used first and then repaid, and the bank's funds are used in advance to enjoy the interest-free period. This is a financial management method. Credit cards can be used as payment tools, and can be directly consumed through POS machines installed by merchants or online payment platforms.
