Introduction to stele pavilions: There are four stele pavilions in the main hall, two on the east and west sides. They were built during the Yongzheng and Qianlong years. They are all built with yellow glazed tiles on the top of the mountain. What is more special is the wordless stele that Yongzheng erected for himself when he was renovating the Imperial Temple in 1729, the seventh year of Yongzheng's reign.
