Go to the counter and withdraw the overpaid money. Don't go to the ATM to get it yourself, because that counts as cash withdrawal, interest collection and repayment.

The cash withdrawal fee is 0.5%, with the lowest in 2 yuan and the highest in 50 yuan. There is also a handling fee for withdrawing your own deposits.

It won't generate interest. But remember to pay back your withdrawal fee.

There is no handling fee for the national deposit of CCB credit cards, and a card number is required.

Across the country, the charges for cash withdrawal are the same, and there is no difference between the same city and different places.

If college students take living expenses from their parents in this way, it is more convenient and the cost is lower.

In addition, I suggest you reduce the number of withdrawals. Because the withdrawal fee is a pen, the withdrawal fee is a one-time fee.
