Longmen Cave, a Taoist temple complex, is located at the foot of Jingfu Mountain in the southern section of the Liupan Mountains, at the border of Shaanxi and Gansu provinces in northwestern Longxian County, Shaanxi Province. Its ancient name was Lingxianyan. It is one of China's five major suspended Taoist temples and the founding place of the Longmen School of Taoism, established by Qiu Chuji. Originating in the Spring and Autumn Period, built in the Western Han Dynasty, and flourishing in the Jin and Yuan Dynasties, it is the "Ancestral Temple of Longmen" of the Quanzhen School of Taoism, thus enjoying widespread renown and being called the holy site of the Longmen School. It has been designated a provincial-level Taoist temple open to the public in Shaanxi Province and a key cultural relic protection unit. Unfortunately, the suspended Taoist temple is currently under renovation, and tourists can only view it from below and cannot climb it. However, even if it were open, I doubt many people would dare to climb up.
