Introduction to the Imperial Stele Pavilion: The Royal Stele Pavilion has an octagonal spire. There is a stone stele in the pavilion, with a height of 3.28 meters, a width of 0.64 meters, and a thickness of 0.23 meters. The stele is engraved with poems and essays written by Emperor Qianlong during his five visits to Chaotian Palace from the 22nd year of Qianlong (1757) to the 49th year of Qianlong (1784). It is rare to see five imperial poems of Emperor Qianlong engraved on one stele.
