Overseas Vietnamese
Under French colonial rule, Vietnam used the units "hào", "xu", "chinh", and "cắc". After independence, Vietnam used "đồng", "hào", and "xu", with 1 "đồng" equaling 10 "hào" or 100 "xu". After the Vietnam War, chronic inflation caused both subdivisions to fall out of use, leaving "đồng" as the only unit of currency. However, Overseas Vietnamese communities continue to use "hào" and "xu" to refer to the tenth and hundredth denominations, respectively, of a foreign currency, such as "xu" for the American cent.
