In some places, there are often "Duobengjiu pine" (rdo-vbum-bcu-gsum, which is 13 Mani stone piles). said. Some seats are connected to form a sacred wall. The wall is considered to be the boundary between the human world and heaven, earth and gods, as well as the intersection and connection point between human world and heaven, earth and gods.
