Introduction to the wordless stele: The wordless stele stands to the east of Sanqing Hall, two feet high and eight feet wide. In the fourth year of Hongwu in the Ming Dynasty (1371), Taoism was cleaned up, Xuanmiao Temple was transformed into Zhengyi Jungle, a Taoist Discipline Department was established, and the incense and fire field was used to pay for the army. This was a major event in the history of Taoist temples, and the writer Fang Xiaoru was specially invited to write a note and lay a stone to commemorate it. The Wu'an stele was originally a stele with the inscription "Cleaning Taoism Stele". After Yan King Zhu Di entered Nanjing, he asked him to draft an imperial edict. However, Fang was killed for disobeying his orders. Ten clans were also exterminated, with more than 870 people dead. In the end, even the inscription he wrote was eradicated and turned into a wordless monument. Although this monument does not have a single word, it is well-known and is one of the three famous monuments of Xuanmiao Temple.
