Generally speaking, the first thing to look at is whether the foreign exchange company is on the blacklist of the State Administration of Foreign Exchange. If so, basically no bank can make money. If not, it will be easy. Basically, large branches or business halls can do it, but bank cards that need to collect foreign exchange have the function of collecting foreign exchange. You can call the customer service number on your card and ask if this card is not available. If so, wait for the foreign exchange to be remitted to the bank before entering the country.
