In 1960s and 1970s, Japan kept the exchange rate of the US dollar too low in exchange for high export rate and rapid economic development. At that time, the exchange rate was about 1 US dollar to 240 yen, but the United States certainly didn't want to, so in 1985, the United States and other five countries forced Japan to sign the Plaza Agreement, demanding that the Bank of Japan not "excessively intervene" in the foreign exchange market, and the yen soared to 1 US dollar to 75 yen. As a result, Japan's economy stagnated for ten years, and the United States returned to 1 to 140 after earning enough yen. Therefore, the purchasing power of the Japanese yen is not much different from that of the US dollar, which is why the Japanese yen can be used as an international payment currency. However, the purchasing power of RMB is very strong. For the same thing, if you want 10 dollars in the United States, it's very likely that you only want 20 yuan in China. In Japan, it costs 65,438+0,000 yen. Therefore, China maintains a huge surplus with the United States every year. At the end of 2006, the United States also blamed the problem on the low exchange rate of RMB, and sent a ministerial delegation to China for negotiations, threatening to impose a tariff of about 30% on all goods imported from China if the RMB did not appreciate.

So if you change RMB into Japanese yen, you can certainly get more than N Japanese yen, but you will find that what you buy is actually only available in China 1/2 to 1/3.
