I have some Thai baht left after my trip to Thailand, about 3, and there is not much left. I don't know where I can find it in Shenyang.

you can exchange foreign currency when you go to an ordinary bank;

The designated foreign exchange settlement bank in China is China Bank, but now almost all banks can convert foreign currency into RMB for ordinary customers.

Bank of China announces the exchange rate of the day according to the international market every day, and then banks of all sizes in the country refer to it. However, the Bank of China has implemented the multi-price system for one day, which means that there may be many different exchange rates for foreign exchange in one day.

Citizens can exchange their ID cards directly at the Bank of China; (The personal exchange quota shall be implemented according to the regulations of the State on foreign exchange control, and the specific quota will be different for different purposes; Specifically, you should consult the local China Bank; )

The exchange procedures in other banks are quite troublesome, and the corresponding certificates must be issued.
