The definition of blacklist is what external media or cardholders say. It is intended to indicate that an individual's credit card or loan has a record of overdue repayment. Because the overdue time is long or the overdue amount is large, it is labeled as a blacklist. In fact, the word "blacklist" will not appear on personal credit reports.

The central bank records personal credit reports, objectively recording the cardholder’s last repayment date, last repayment amount, and latest repayment time. Based on the cardholder's last payment date, the payment amount and the time of the latest payment, the bank or lending institution determines whether the cardholder has overdue repayment. Therefore, instead of saying "blacklist", it is more correct to say late repayment.
