Extended data:

The fluctuation of a country's foreign exchange market will have an impact on import and export trade, economic structure and production layout. Exchange rate is the most important adjusting lever in international trade. A falling exchange rate can promote exports and curb imports.

For example, if the exchange rate of RMB against the US dollar is 0. 1502 (indirect pricing method), the price of a commodity in the United States is 15.02 US dollars. If the exchange rate of RMB against the US dollar drops to 0. 1429, that is, if the US dollar appreciates and the RMB depreciates, you can buy this commodity with less dollars. The price of this commodity in the United States is 14.29.
