Introduction to Tianyuan Peak: This scenic spot is located in the center of Kongshan Tianbon Scenery Area. It consists of three raised peaks. The main peak is about 120 meters high, and the east and west side peaks are about 80-100 meters high. They are the remnants of water erosion in karst basins, and are also called isolated peaks or dissolved hills. Judging from the shape, due to the steepness of the mountain, it looks like three chisels used by stonemasons standing in the sky basin. The locals also call it "Chisel Rock". Looking down from Kongshan Tianpen Observation Deck, it looks more like a "black gauze hat" worn by ancient officials, so tourists also call it "Guanmao Mountain".
