At present, there are three main ways of foreign exchange, one is bank exchange, the other is internet exchange platform exchange, and the other is spot foreign exchange. Among these three ways, bank exchange is more practical, safer and more suitable for international students. In addition, the whole face value and small change can be exchanged in the bank, and foreign exchange can also be accessed. Of course, there are places to exchange foreign currency abroad, but it is still recommended to exchange foreign currency in China before departure, because the foreign currency exchange rate of domestic banks is very cost-effective and difficult to handle.
