Introduction to the ancient water mouth of Wuling River: Nanping Village is surrounded by mountains and rivers. The architecture of the ancient water mouth at the head of the village is pleasing to the eye. A 40-meter-long three-hole stone arch bridge "Wansong Bridge" crosses the Wuling River. Facing Wansong Bridge, there are ancient buildings such as Leizu Hall, Wenchang Pavilion, Guanyin Tower and Wansong Pavilion; behind is Wansong Forest, with dozens or hundreds of towering ancient trees standing majestically.
