Introduction to the stele pavilion: Compared with the Bell and Drum Tower, there are two stele pavilions, which contain the "Imperial Stele of Hongren Pu Ji Tianfei Palace" by Chengzu of the Ming Dynasty and the "Record of the Tianfei Lingying" by Zheng He. The two inscriptions record the experience of Zheng He, the eunuch of the Three Treasures of the Ming Dynasty, who was repeatedly blessed by the concubine and completed seven voyages to the West.
