I used the Great Wall Electronic Debit Card of China Bank to get my own card. It seems that I have been deducted 3 yuan every month for several months. What's going on here?

At present, large banks generally have small account management fees.

Because after you open the card, the bank needs to invest manpower and material resources to do some management work for your money.

When the money in your card doesn't reach the standard amount, they will deduct 3-5 yuan every month.

This is one of the few you have.
