Jin Ping Mei is an extraordinary novel from the Ming Dynasty that draws on the story of Water Margin to depict the urban life centered around the character Ximen Qing, exposing the corruption of Ming society. Although the book features characters from the Song Dynasty, it actually reflects the social phenomena of the Ming era. The author of Jin Ping Mei is credited as 'Lanling Xiaoxiao Sheng,' but their true identity remains a mystery to this day. Scholars have proposed various theories, including candidates like Li Kaixian, Jia Sanjin, and Wang Shizhen, but none have definitive evidence. Wu Han, through thorough historical research, has refuted the traditional view that Wang Shizhen is the author. In recent years, some scholars have suggested that Xu Wei might be the author, but this theory has yet to gain widespread acceptance. The mystery of Jin Ping Mei's author is like a layer of fog, waiting for future generations to unveil.
