Why is it said that the available balance is not enough to be paid by Weizhong bank card reserve?

The reason why the available balance of reserve fund of Weizhong bank card is insufficient is that Weizhong bank doesn't want you to continue lending, so it cancels your reserve fund loan amount.

In this way, you often have some borrowing or overdue behavior on other small loan platforms, which was discovered by Weizhong Bank and asked him to cancel some of your quotas, so you can't use them.
