Foreign exchange refers to the act of converting one currency into another. This behavior generally occurs between two countries and involves the conversion of different currencies. Foreign exchange mainly meets the needs of international trade and tourism, and can also be used for speculation or value preservation. Foreign exchange will be affected by the exchange rate, that is, the ratio between currencies of different countries.

In foreign exchange transactions, we often need to pay attention to the change of exchange rate. Exchange rate refers to the identification value between one currency and another, and it is the embodiment of the relationship between supply and demand in the market. The exchange rate will be influenced by many factors, including the economic situation, trade relations and political situation of various countries. Therefore, we should be vigilant in foreign exchange, pay attention to exchange rate changes, and reasonably choose the time and method of exchange.

Foreign exchange can generally be carried out in banks, exchange malls, airports and other places. Different places and ways will have different exchange rates and fees. Some banks will offer more favorable exchange rates and fees, while airports and trading malls may charge higher fees. Therefore, in foreign exchange, we need to comprehensively consider all aspects and choose the most cost-effective exchange method.
