Extended data:

The exchange of commodities is related to the country's economic history and monetary policy, and has nothing to do with economic strength. In an open economy, it depends on whether the country adopts a floating exchange rate or a fixed exchange rate. Fixed exchange rate, the country buys or sells its own currency in the foreign exchange market to maintain stability. If it is a floating exchange rate, it depends on the purchasing power of the country's currency. There are actually many factors.

Involving a discipline-international finance, it can provide a basic theory of purchasing power parity, that is, something can be bought at someone's place 1 USD, while RMB can only be bought at home in 7 yuan. The purchasing power of the same thing is expressed in dollars (of course, it is actually related to the price level).
