It didn't work. The range of change is only within 3%, and it is still floating up and down. Even ordinary people, when exchanging foreign exchange, the difference is less than 3%, so it is impossible to get rich or go bankrupt. The main function of foreign exchange reserves is as a backup of payment means. China's total annual import is only $65,438 +0.5 trillion, that is to say, even if China does not export for two years, its foreign exchange reserves are sufficient (nothing more than realizing bonds). Needless to say, China's foreign trade exports exceed $65,438 +0.5 trillion every year, and it is still earning foreign exchange continuously. Therefore, even if the foreign exchange reserves fall by half again, it will be enough. Moreover, depreciation is beneficial to our export enterprises. It has no obvious influence on ordinary people.
