Introduction to Dashi City: Dashi City is another wonder of Huoshizhai, located 1 km south of Chanyao Village. The so-called Stone City is actually the name that people use to visualize the specific geology and landforms here. Stone City can be divided into two parts: the inner and outer cities. The "inner city" is shaped like a lying cow, abrupt and isolated, living alone in the center. The circumference of the bottom is 900 meters, and the vertical height is more than 50 meters. This crouching inner city rises from the ground, and is surrounded by sheer cliffs on all sides. It is impossible to climb. However, there are 80 manually dug stone steps in the southeast corner that can barely reach the top. Its top is in the shape of a cow's back, 338 meters long from east to west, 120 meters wide from north to south, and covers an area of ​​40,000 square meters. There are 6 artificially dug vertical hole-type rectangular pools from east to west in the middle of the top of the mountain, and a grotto at the east end. There are artificially dug column holes. Around the bottom of the inner city, there is a gentle slope of about 26 hectares, which has been reclaimed as farmland. The outer edge of the gentle slope is surrounded by towering cliffs, with a vertical height of about 100 meters.
