Building introduction: The traditional dwellings of the Qiang people are made of rubble, pebbles and clay. Most of them are two to three-story flat-roofed stone buildings. The first floor is for raising livestock, and the second floor is for people's living rooms. There is a fire pit with an iron triangle in the main room, which is used for cooking. The fire in the fire pond continues year after year, and the Qiang people call it "ten thousand years of fire". The third level is often the space where gods move. There is a "Nasa" tower made of stones on the roof, and the white stones placed on it represent the mountain god. There is also a granary made of wooden boards on the roof.
