Hong Kong dollars have not been used up. How can I change them back and where?

There are three major banks in China that can be exchanged: Agricultural Bank of China, Industrial and Commercial Bank of China and Bank of China.

Because different banks offer different services and exchange different currencies, it is suggested that you also "shop around" to exchange foreign exchange and purchase foreign exchange. Unused foreign exchange belongs to foreign exchange refund, and it needs to go through the formalities of foreign exchange refund. Foreign individuals who have not used up their original RMB exchange can apply for exchange with their valid identity documents and the original exchange memo of China Bank. The validity of the original exchange memo is 24 months from the exchange date. For the exchange of less than the equivalent of $500 (inclusive) on the same day and the equivalent of 1000 (inclusive) on the day before leaving the country, you can handle it with your valid identity document.

2. Tips:

The exchange rate changes in real time. Please make a replacement decision within the effective time. Once the transaction is completed, it can't be cancelled.

Some currencies are only handled at some outlets.
