It is very important to settle foreign currency in the bank, so you don't need to fill out any settlement application. You only need to fill in a withdrawal notice, fill in the currency and amount of foreign currency to be settled, stamp the corresponding bank seal, and tell the window staff to "settle foreign exchange" at the bank. The bank will fill out a "foreign exchange purchase and settlement voucher" for you according to the foreign exchange quotation of the day. The voucher contains the amount of foreign currency you settled and the amount of RMB entered into the account, so you can use it for bookkeeping.
