2. If the bad record is not caused by the bank, it cannot be revoked manually.
3. Personal loans overdue's bad record will exist forever.
4. Bad records caused by overdue repayment of credit cards can be covered within 24 months after normal repayment. Only the repayment records of the credit card in the last 24 months are kept, but the card will be cancelled after the arrears are settled, and the overdue records will exist forever.
It is suggested not to cancel the card after clearing the arrears, but to cover the overdue record with a good record of timely repayment. (There may be a lag in system update, which may be delayed by 2-3 months).
