In Vietnam, tooth painting was practiced by the majority Vietnamese people as well as by minority ethnic groups. Si La men paint their teeth red and the women paint theirs black. This practice has slowly declined with each new generation. The Baiyue in southern China and northern Vietnam practiced teeth blackening. When Han Chinese ruled the Vietnamese in the Fourth Chinese domination of Vietnam due to the Ming dynasty's conquest during the Ming–Hồ War, they imposed the Han Chinese style of men wearing long hair on short haired Vietnamese men. Vietnamese were ordered to stop cutting and instead grow their hair long and switch to Han Chinese clothing in only a month by a Ming official. Ming administrators said their mission was to civilize the unorthodox Vietnamese barbarians. The Ming dynasty only wanted the Vietnamese to wear long hair and to stop teeth blackening so they could have white teeth and long hair like Chinese. A royal edict was issued by Vietnam in 1474 forbidding Vietnamese from adopting foreign languages, hairstyles and clothes like that of the Lao, Champa or the "Northerners" which referred to the Ming. The edict was recorded in the 1479 Complete Chronicle of Dai Viet of Ngô Sĩ Liên.
