Remittance business refers to foreign exchange such as inheritance, real estate, stock payment, dividends, deposit principal and interest, industrial injury compensation, traffic accident compensation, pension, pension and insurance. Residents in China are repatriated abroad or in Hong Kong and Macao through the Bank of China.

Settlement of foreign exchange means that all domestic enterprises, institutions, organs and social organizations (except foreign-invested enterprises) must promptly repatriate foreign exchange income within the prescribed scope in accordance with the provisions of the state foreign exchange management regulations, and sell all foreign exchange income to designated foreign exchange banks at the exchange rate listed in banks. There are many ways to settle foreign exchange, such as compulsory settlement, willingness settlement and quota settlement.
