Erlong Mountain Scenic Area is located in the southwest of Dongtan Village, Qingcheng Town. It was built in the late Ming and early Qing Dynasties and covers an area of more than 8,000 square meters. The building complex is built on the mountain, with a magnificent atmosphere, rigorous layout and unique style. Because its mountain is like "Erlong Opera Pearl", it is named Erlong Mountain. The most complete preservation of Erlong Mountain Scenic Area is the ancient opera house built in the 16th year of Qing Qianlong (1751). In recent years, the Jade Emperor Palace, Erlongshan Temple, Dai Temple, Wenchang Palace, Sansheng Palace, etc. have been restored, which has preserved the original historical style and added a new cultural color.
