Yes, all credit cards in my country are networked nationwide. You can withdraw money at any UnionPay unit, but fees will be charged. If it is withdrawn from another bank, more fees will be charged. If it is from the postal service, it will only be withdrawn at another bank. It is recommended to use a postal card if it is cheaper to withdraw money in an area. CCB’s card charges 1 yuan per 100 yuan for out-of-town transfers, while the postal service charges a percentage and is much cheaper. By the way, I wish you a happy time.
