2.VISA, MASTER and American Express credit cards can all pay US dollars and RMB.

China International Credit Card can only pay US dollars, and the annual fee is fixed and cannot be reduced. It's not worth it at all

China International Credit Card, you must go to the outlet to get the card and cancel it. When you get the card, I suggest you cancel it directly.

Apply to different banks as soon as possible, and ask before applying.

Whether it is a dual currency card of RMB+USD, whether it supports online payment, and what is the limit of each payment.

The salesman and the counter may not know the last question, so they should call the credit card customer service to ask.
