Introduction to Longtou Temple: It was originally called Tayantou. It was named after the original Kongwang Pagoda Courtyard on the loess slope under the rock. Later, the name was changed because Li Shimin, Emperor Taizong of the Tang Dynasty, came to Mianshan to pay tribute to the rain and saw the appearance of two dragons. There are more than 20 scenic spots including Shengyi Pavilion, Bailong Wall, Guandi Temple, Nantianmen, and Longmen Stone Archway.
