The appreciation of RMB means that exports decrease and imports increase greatly. And vice versa? During the period of RMB appreciation, foreign exchange income increased for a short time, but this is due to the result of previous work, and everything has a buffer process, which also shows that when the RMB falls, people will still see that foreign exchange is decreasing and imports are still increasing in the early days, and the struggle needs a buffer opportunity. Excessive or inappropriate increase in foreign exchange income is not a good thing, it will increase foreign exchange risks, which is not conducive to the country's foreign exchange regulation, thus triggering a series of economic problems according to law and turning into a financial storm.
