The temporary credit line of China Merchants Bank shows that all the arrears are recovered because of state-owned enterprises. According to relevant public information, after the credit card repayment of China Merchants Bank, as long as it is within the validity period, the temporary quota will be restored, and the quota before the expiration of the validity period will be invalid. Therefore, the credit line has not been restored after the user repays, and most of the temporary credit lines have expired. At this time, the user needs to apply for a temporary quota again, and the newly applied temporary quota will be given a new validity period.
