The exchange rate of foreign exchange is foreign exchange divided by RMB, for example, US dollars divided by RMB. If the value of the US dollar remains unchanged and the RMB appreciates, what will the RMB converted from one dollar do? Without it, the value of the dollar divided by the renminbi will rise, and the exchange rate will rise. People abroad will feel that buying China products is not affordable, which will reduce the difficulty of buying and exporting. However, with the development of China today, the wealth created by exports is getting heavier and heavier, which is not conducive to the economic development of China. Lowering is the opposite.
