A: The error did not specify whether the foreign currency exchange rate rose or fell or whether the local currency exchange rate rose or fell. Because there are two pricing methods of foreign currency exchange rate, namely direct quotation method and indirect pricing method. Direct quotation is the exchange rate expressed by converting a unit's foreign currency into a de facto domestic currency (that is, the price of a unit's foreign currency is expressed in domestic currency). Indirect pricing method is an exchange rate expressed by converting a unit's local currency into a certain amount of foreign currency (that is, expressing the price of the unit's local currency in foreign currency). Obviously, the exchange rates under the two pricing methods should be mutual. Corresponding to direct quotation, the rise of foreign currency exchange rate means that unit foreign currency can be exchanged for more domestic currency, that is, the local currency depreciates; On the contrary, the decline of foreign currency exchange rate means the appreciation of local currency. Only under the indirect pricing method, the rise of foreign currency exchange rate means that the unit local currency can be exchanged for more foreign currencies, that is, the foreign currency price of the local currency rises and the local currency appreciates; On the contrary, the decline of foreign exchange rate means the depreciation of local currency.
