It is a kind of red and green treasure in Tibetan costumes, which is one of the traditional Tibetan folk decorations. It consists of beeswax, dzi beads and coral. It is a gem that Tibetans often start with. It is easy to carry and beautifully decorated. In ancient times, Tibetans mainly lived in today's Xizang Autonomous Region and southern Qinghai. Most of them are nomadic people, and aquatic plants migrate with the change of seasonal climate. Nomads live on aquatic plants and have no fixed residence. When they moved, Tibetans exchanged their inconvenient property for precious gems to carry with them.
