Dao tribe woman (Mèo Vac, Vietnam)
Women of the Dao tribe often wear beautiful headwear with many metal pins holding their hair.
The teeth covered with gold-like metal indicate that this woman is married. It's convenient: as soon as the woman or teenage girl smiles, you know if she is single or not! Girls from ethnic minorities (i.e. tribes) marry at about 14 or 15 years of age.
