Mangdang Mountain is located in Yongcheng, Henan Province. It is a national AAAAA-level scenic spot that combines natural wonders with historical heritage. As the "Han Culture Corridor", the scenic area has a rare group of Western Han Dynasty tombs in the world. The tombs of Liang Xiaowang and the Queen's Tomb were carved into the mountain and have exquisite structures. The "appearance" wonder of Liu Bang's Snake-Slaying Stele at night has been passed down for thousands of years; Confucius Mountain retains the remains of Confucius's teachings in the rain, and the Mangshan Temple is surrounded by smoke and fire, where Confucianism, Buddhism and Taoism are integrated. In the unique limestone landform, geological relics such as ripples and fossils are like natural textbooks, adding a sense of humanistic depth to the mountains and rivers.
