It's better for China Bank to exchange foreign currency. Because banks in China can exchange the most foreign currencies. For example: British pound, Hong Kong dollar, US dollar, Swiss franc, Singapore dollar, Swedish krona, Danish krona, Norwegian krona, Japanese yen, Canadian dollar, Australian dollar, Euro, Macau dollar, Philippine peso, Thai baht, New Zealand dollar, Korean won, etc. A large number of exchanges need to be made in advance. Because you need to bring an ID card to exchange foreign currency, each ID card can handle up to 50,000 US dollars, or other foreign currencies equivalent to 50,000 US dollars. For example, 1.67 pounds can be exchanged for 1.67 dollars, so you can exchange up to 50000 pounds/1.67 pounds.

If you change more than $50,000, you need to apply to the bank. You can also apply for another $50,000 with your family ID card. Currency with low liquidity also needs to make an appointment in advance. There is no handling fee for each bank to exchange foreign currency, but it will earn a spread, and the spread of China Bank is the lowest.

Industrial and Commercial Bank of China, China Construction Bank and Agricultural Bank are all acceptable, but there are not as many convertible currencies as China Bank. In other words, the four major banks can handle foreign currency exchange business at present.

China Merchants Bank and Bank of Communications can also handle it. If the credit cards of China Merchants Bank and Bank of Communications have a limit of RMB 30,000, there will be equivalent US dollars to be withdrawn, that is, US$ 30,000 /6. 12 = 4902.

To handle foreign currency exchange business in a bank, you need to bring one of the following valid documents: my ID card, household registration book, military ID card, Hong Kong and Macao residents' passes to and from the Mainland, passports, and fill out a foreign exchange form in accordance with bank regulations. Different bank outlets have different foreign currency reserves, so it is better to choose a higher level. At present, 130 overseas countries and regions have covered the network of unionpay, so when spending by credit card abroad, as long as the other party has the logo of unionpay, the payment can be completed with unionpay cards issued by domestic banks.

Note: Not all business halls can handle foreign currency exchange. In some cities, only some business halls can handle foreign currency exchange. Please call in advance to confirm. As mentioned above, there are many convertible currencies in China banks, and ordinary banks can only exchange them: US dollars, Japanese yen, British pounds, Hong Kong dollars, euros, Australian dollars and Swiss francs.
