Why do you want to withdraw money? There is a handling fee for withdrawing cash. When you pay at the supermarket near your preparatory school, you can directly swipe your card without any fees. I still don’t understand why the kids who came here always use credit cards to withdraw cash, but no one swipes the card for consumption? I have a dual-currency card from China Construction Bank, and I have never had any problems wherever I can swipe the card for consumption, unless the limit on the card is completely overdrawn by me
