Every period is different. In the early and late Ming Dynasty and the early and late Qing Dynasty, the same was true of RMB, and Chairman Mao's RMB was not the same as the current RMB. For example, renting a house in the 1970s 1 10 cents a square, and renting a house of more than 30 square meters is a few cents a triangle. Now it's more than 500 yuan, as shown in the picture, in kind.
