Introduction to Longtan Gorge: Longtan Gorge, also known as Qili Gorge, is located at the southern end of Shuanglong Town. The Majia River flows through the canyon, merges into the Xiang River to the north, and merges into the Lan River to flow into Yinghu Lake. The entire canyon is about seven miles long. Hence the name. Longtan Canyon is between 20 and 30 meters wide, with a drop of about 80 meters. From the entrance of the scenic spot to the Longxi Mountain, it looks like a giant dragon winding and circling in the valley. Along the way, due to the action of the mountains and water, there are layers upon layers. Nine pools of different sizes and shapes are formed, just like a dragon has nine sons, all of which are different. The nine sons of the dragon condense the spirit of the dragon, permeate the culture of the dragon, and interpret the rise and fall of the Chinese nation.
