Cliff introduction: Tulou Temple belongs to the Danxia landform, which is almost entirely made of horizontal purple-red sandstone and conglomerate. The hard rock layer bulges outward like the eaves of a roof. Temples and halls are built on it, and the halls are suspended high. The plank roads and corridors connect the temples, pavilions and caves, so that there are holes in the temples, and there are holes in the caves, and the Buddhas are hidden in the caves. The plank roads and winding corridors are close to the cliffs, and even suspended in the air.
