Abstract: Among the names of Li Kaixian’s and Jia Sanjin’s forefathers, many were homographic or homophonic with the names of humble characters and anti-heroes in Jin Ping Mei. If the author of Jin Pin Mei really is Li Kaixian or Jia Sanjin, they could never do so in that ancient time stereotyping to taboo. In addition, it seems that the author is unfamiliar with the geographic conditions of Tai Mountains. Thus, a deduction can be made that the author of Jin Ping Mei can not be Li Kaixian or Jia Sanjin.

Key words: author of Jin Ping Mei, Li Kaixian, Jia Sanjin
