Introduction to Yulong Cave: It is 1,000 meters away from Shenxian Cave. Li Shangyin, a great poet of the Tang Dynasty, visited this cave during the Dazhong period and left poems. The cave is grand, deep and open, divided into four seas in the east, south, west and north, two halls and eight palaces. It travels both by land and water, with a flat path and sparse and orderly landscapes that change with each step.
