Yunlongxuan Original Ecological Scenic Area is located in Lianyungang Development Zone, known as the "Zhangjiajie Huangguoshu" in Jiangsu Province. Unfortunately, it was cold, and the thick ice and icicles of Tianquan Waterfall were frozen. Due to time constraints, I could not climb to the top to see the clear water deep pool. I could only stay for the opportunity to watch it later.
