The surface of the Nacang black tent is made of natural yak hair, which is hand-woven by herders. It can be repaired and sewed modularly, reflecting the unique wisdom of the pastoral area. In terms of structure, it adopts a bent keel frame made of bamboo and steel pipes, and the frame size can be limitedly adjusted. It can be matched with different scenes, and the black yak hair fabric on the outside can well prevent the interference of surrounding light, allowing people to focus more on various activities.
