Building introduction: Most of the Qiang buildings are made from nearby materials, using soil, stone and other resources from nearby mountains, and large pieces of stone are used to build the footings in the ditch. It is about three feet wide, and then the prepared yellow mud is used as slurry to glue the stones together. The stone wall gradually becomes thinner from bottom to top and becomes smaller layer by layer. The center of gravity of the stone wall is slightly tilted toward the interior, forming a centripetal force that squeezes each other to become firm and stable. The roof structure levels from bottom to top are main beams, rafters, split wood layers, bamboo poles, yellow thorns, and brown rakes, which are quite ethnic.
