Introduction to the canyon: The nine peaks of Jiulian Mountain are intertwined and the mountain moves, forming three huge canyons: Xiliangou, Guanhou Grand Canyon and Hongyan Grand Canyon. The three canyons are surrounded by a triangle. The rocks are like axes, the peaks are like knives, the waterfalls are like drills, and the shallow pools and creeks at the bottom of the valley are like jasper. Due to the influence of geological structures and rock type distribution, the mountain landscape types are complex and diverse, with undulating mountains and deep valleys. Dense and steep.
