Direct quotation uses its own currency as a variable. Take China and the United States as examples, so in China, 1 USD =6 RMB is the direct quotation.

Indirect pricing method uses foreign currency as a variable. Take China and the United States as examples, then in China, 1 RMB = 1/6 USD is an indirect pricing method.

It is worth noting that most countries in the world now calculate exchange rates on the basis of US dollars. America is based on the pound. Except for Britain, almost all countries that use indirect pricing method quote directly.

When you say that the exchange rate of RMB against the US dollar is rising, if it is a direct quotation, it means that 1 US dollar can be exchanged for more RMB, that is, RMB depreciates. If it is indirect pricing, it means that RMB 1 can be exchanged for more dollars, that is, RMB appreciates.

China quoted RMB directly against the US dollar, so it should depreciate under this condition.
