Introduction to the Nan Pavilion of the Imperial Stele: The Nan Pavilion of the Imperial Stele was built by Qianlong when he visited the mountains. The pavilion has an octagonal shape, a double eaves roof, four corners each, and an exquisite structure. In the middle of the pavilion stands a tall inkstone royal stele, which is divided into three parts: the stele cap, the stele body, and the stele base. Around the stele are engraved four five-character poems written by Qianlong during his four visits. The contents are mainly some of Fan Zhongyan's words of praise.
