The Khang ethnic group, also called Xa Khao, Xa Xua, Xa Don, Xa Dang, Xa Hoc, Xa Ai, Xa khang Bung, Quang Lam live in Son La and Lai Chau provinces.
The Khang live in houses built on stilts, with three rooms. Each house has two kitchens, one kitchen is used to cook daily meals and the other is used to warm and cook meals which are offered to worship dead parents. Khang marriage ceremonies go through three steps. First, a marriage proposal is made. Next, parental approval is sought; and finally the wedding occurs. The first stage is held for the groom’s family and the second stage is held in order to accompany the bride to her husband’s home.
Khang ethnic women dye their teeth black and chew betel like the Thai.
The Khang mainly practice slash-and-burn cultivation using traditional techniques such as digging holes and planting seeds in these holes. They grow sticky rice which serves as their food staple. Their weaving products include chairs, baskets, flat baskets, suitcases, packs, and wooden boats. The Khang also grow cotton and exchange it for cloth and garments.
