The currency conversion fee of different card issuers will be different, which is generally 1.5%. However, it should be reminded that at present, most merchants in China are laying UnionPay credit cards and do not support pure foreign currency cards without UnionPay logo. If there is no UnionPay logo on your foreign credit card, be sure to ask the merchants whether their credit cards can be swiped by foreign organizations such as Visa and Master.
