Luoquanyan Sinkhole

　　Luoquanyan Karst Cave, also known as "Luoquanyan Sinkhole," is located in Group 2 of Luochuanyan Village, Jiaoyuan Town, right next to National Highway 209. The cave is gourd-shaped and extends vertically from the ground, with a roughly circular opening covering an area of about 30 mu. The cave extends approximately 300 meters deep, with an underground cavity spanning around 200 mu. A large, pitch-black cave entrance is even visible on satellite maps. The cave entrance forms and extends from the hillside behind the home of Tang Guoqing in Group 3 of Luoquanyan, featuring natural landscapes inside such as mountains, water bodies, and uniquely shaped, diversely formed rocks, making it highly attractive for sightseeing. It holds great potential for development, where an underground town could be constructed, creating a earthly paradise.
