When China sells so many things to foreigners every year, it will naturally get a lot of foreign exchange! China used foreign exchange to buy foreign things, but bought less, and still had some foreign exchange in his hand. This is the so-called trade surplus, and the United States talks about it all day! China has a surplus year after year, accumulating inexhaustible foreign exchange year after year, and finally becomes the first foreign exchange holder in the world! If you have more foreign exchange, you will buy US Treasury bonds or something.

This has nothing to do with printing money! Printing more RMB will lead to excessive domestic currency and inflation. The country has always attached great importance to controlling inflation, especially in recent years. How can we print more RMB to buy foreign exchange? China has so much foreign exchange that I don't know what to do!
