Introduction to Niangziguan Waterfall: There is a flying spring under the Jealousy Nu Temple about 300 meters near the east gate of Niangziguan Castle. It is named Niangziguan Waterfall because it is near Niangziguan. It is the source of Zefa Water, also known as Water Curtain. Hole. There are flying waterfalls, suspended hundreds of feet, scattered like beads, and there are numerous springs in the valleys of the mountain city. Xuanquan, known as "Sea Eye" by the locals, is the largest of the springs. The waterfall has a height of more than 30 meters and a width of more than 10 meters. The "Sea Eye" spring water rolls, stirring up layers of white spray and making a deafening sound. Spring water gushes from the flat ground, pours down from the cliff next to the "Sea Eye", and merges into the Tao River to form the Shuiliandong Waterfall.
