If the bank refuses to open a first-class account, it can directly refuse first. To put it mildly, I'm sorry, but I have a bank loan to pay back.

Moreover, the bank card that goes to the bank now has only one first-class card in its name, and there is no limit on the transaction amount of this card. If you continue to apply for other bank cards, it belongs to the second-class card or the third-class card, which has great restrictions on the transaction amount and can greatly limit fraud.
