Hey, it is a hand-woven wool fabric of the Tibetan people, which has been loved by the Tibetan people for thousands of years. Zhakou County is located in the south-central part of Tibet, in the middle reaches of the Yarlung Zangbo River, and in the south of the Gangdese Mountains. In the Tibetan language, “the sac” means “in the thorn tree ditch and in the mountain peach forest”. Due to the narrowness of the population and the lack of resources in history The sacs are mostly engaged in hand-made and business, and the long history of hand-made makes Zhasu County a reputation of “hometown of 氆氇”.
