The exchange of RMB for foreign exchange does not mean that you take RMB to the United States or Europe and say that I want to change it, and people will change it for you. So there are many foreign currencies that can be exchanged for RMB appreciation. That means you change it at home, want to change it abroad, and people ignore you. What your teacher said is wrong.

With the appreciation of RMB, the change of foreign exchange reserves will increase, because if you are a foreign investor, you know that RMB will appreciate at this time, you must change your money into RMB in advance, and then change it into foreign exchange after the appreciation, so that you can make money. That's what hot money does, so the appreciation of RMB will not necessarily reduce foreign exchange reserves. Only when the RMB is expected to depreciate and foreign capital flows out in large quantities will it decrease, resulting in insufficient solvency. This explanation is not necessarily correct.

The answer is correct. This is because the original RMB to the US dollar was 8: 1, and now it is about 7: 1. I change my foreign exchange into RMB at 8: 1, and 1 US dollar can be changed into RMB 8. It's 7: 1, and my 8 RMB can be changed into 65438.
