Lạc Việt
A Chinese text dating from the 220s BCE reporting "unorthodox customs" of the Yue in a part of the Lạc Việt region states:“To crop the hair, decorate the body, rub pigment into arms and fasten garments on the left side is the way of the Baiyue. In the country of Xiyu () the habit is to blacken teeth, scar cheeks and wear caps of sheat [catfish] skin stitched crudely with an awl.”
