Introduction to Longquan Cave: Xuancheng Longquan Cave is located in Shuidong Town, Xuanzhou District. It is also called Yaotou Cave and is a limestone cave. Tourists came here as early as 700 years ago. On the cave wall, there is a poem written by Xu Shihong in the first year of Kaiqing in the Southern Song Dynasty (1259): "The layers of strange rocks are thousands of years old, and the twists and turns are quiet and interesting in nature. There should be dragons soaring in the clouds and changing, and coming to the world in spring." Since its development in 1978, this underground palace has attracted the attention of tourists. The cave is winding and majestic, with stalactites, stalagmites and stone pillars everywhere. The strange stone platform has various images and is lifelike. There are seven halls in the cave, the largest one is more than 1,000 square meters, and the smaller one is 200 to 300 square meters. There are more than 20 poems written by ancient people from the Southern Song Dynasty to the Qianlong period of the Qing Dynasty on the cave wall.
