CCB’s Hebei etc credit card is a UnionPay ic credit card, and this card is in RMB single currency. When you spend money overseas, you can use it as long as you have a UnionPay POS machine. No matter what currency you spend, it will be directly recorded in RMB, and there is no exchange fee. When you return home, you only need to return the RMB directly, which is very convenient.
