It won't matter if CCB's credit card is overdue for one day, but the premise is that within the grace period of CCB's credit card, the grace period of CCB's credit card is three days, and paying off the bill within these three days is a timely repayment. However, if the grace period is exceeded, interest will be charged on a daily basis, and it is also possible to collect credit. If it takes a long time, CCB will collect it in various ways, and if the circumstances are serious, it will sue you. It is suggested that you pay off your debts in time to avoid more serious impact.
