In the past seven years, the appreciation of RMB has exceeded 20%, which is not significant in terms of the appreciation of currencies in various countries. Most of the above 20% appreciated in the first four years and only 34% in the last three years. In international trade, it is a common phenomenon that one country's currency fluctuates by 34% a year against another country's currency.

The so-called export difficulty is determined by China's industrial structure. China's competitive export products are all products with low added value, low profit and high pollution. They have no core competitiveness and are at the low end of the world industrial chain. They can only win if they bargain with each other. Such an industrial structure, one of the environmental problems caused by itself, is unsustainable. The bankruptcy and elimination of backward enterprises and the optimization and transformation of economic structure are inevitable.

In addition, most of China's products have no pricing power in the world, and the depreciation of the RMB has led to a decline in the purchase price of foreign investors, leaving most of the profits abroad. But because they are low-end products, such as shoes, clothes, lighters and electrical appliances, many of them are just needed. In recent years, although the RMB in China has appreciated slightly, the foreign trade volume has increased rapidly and the surplus has been expanding. By the end of 20 13, China's foreign exchange reserves had reached nearly 4 trillion US dollars, more than three times that of Japan, the second largest country in the world (about 1.2 trillion US dollars in Japan). The continuous and rapid increase of the surplus makes the security of China's 4 trillion US dollars (5 trillion, 8 trillion in the future, 10 trillion) foreign exchange reserves face great risks ~ ~ ~
