The most famous building complex on Mount Cangyan is the Fortune Celebration Temple (). It was first erected during the Sui Dynasty and is said to have been the place where Princess Nan Yang, the daughter of the Sui Emperor Yang, practiced Buddhism. The various structures of the Fortune Celebration Temple (the Tablets House, the Hall of the Heavenly Kings, the Hall of the Giant Buddha, the Bridge-Tower Hall, the Buddhist Canon Depository) are well integrated into the mountain topography. The central landmark of the complex is the Bridge-Tower Hall (). As the name suggests, it is supported by a stone arch bridge spanning a narrow gorge. The bridge has a span of 15 meters and stands 52 meters above ground, it is constructed from 365 stone blocks. Under the bridge a stone staircase with more than 360 steps leads up to the summit.
