The conversion formula between Japanese yen and RMB is Japanese yen = RMB * exchange rate. Exchange rates are divided into direct quotations and indirect pricing methods. The direct quotation method, also known as the price payable method, is to calculate how many units should be paid in the local currency based on a certain unit of foreign currency (1, 100, 10000,10000). It is equivalent to calculating how much local currency should be paid for purchasing a certain unit of foreign currency, so it is called the payable price method. In the international foreign exchange market, including China, direct quotation is currently adopted. For example, the exchange rate of Japanese yen against US dollar is 1 19.05, that is, 1 US dollar is 1 19.05 yen.

Indirect pricing method is also called accounts receivable pricing method. It calculates the foreign exchange receivable currency of several units in the domestic currency of a unit (such as 1 unit). In the international foreign exchange market, euro, pound and Australian dollar are all indirectly priced.
