The country's foreign exchange reserves are not simply dollars bought with RMB, and every penny of the country's foreign exchange reserves is exchanged for goods from our country.

When China exports goods to the United States, American importers must pay the factory in China, and they pay dollars. Then the dollars paid to me are not left in the factory's own hands, but exchanged for the country through RMB, and the country saves these dollars one by one for a rainy day.

If the exchange rate between the US dollar and the RMB was 1:8 last year, then every 1 dollar saved by the state was exchanged for RMB goods in 8 yuan. If the national reserve is 2 trillion, then we changed it to RMB 16 trillion. If you sell this $2 trillion, you should exchange it for something corresponding to 16 trillion RMB!

But if the dollar falls to 1:6 against RMB, then the $2 trillion we have saved can only be exchanged for 12 trillion RMB, and 400 million RMB will evaporate in vain!

I won't talk about the above numerical algorithm here. If you can understand the above analysis, then you can understand the data!

"supplementary question: the dollar has fallen and the renminbi has risen. Can't you buy more dollars or other foreign exchange currencies? "

A: As mentioned above, the country's US dollar reserves are not directly exchanged with RMB. RMB is not an international currency and cannot circulate in the world. To others, it is just a piece of waste paper. Why should others exchange with you? Therefore, China should speed up the internationalization of RMB!
