傳奇家李公佐的身世一直為學界所關注。通行的看法是「傳奇家李公佐」非「千牛備身李公佐」。本文在前人研究基礎上，結合新發現材料，對李公佐的身世進行了重新考察。從「千牛備身」入手，通過官職、年齡、交往、家庭信仰等方面的分析對比，尤其是李公佐與薛蘋關係的揭示，證明瞭「傳奇家李公佐」與「千牛備身李公佐」實際上就是同一個人，從而揭開了長期不明的李公佐身世之迷。 The life experience of the legendary novel author Li Gongzuo has been concerned by academic circle. The prevailing view believes that ＂Li Gongzuo the author＂ is not ＂Li Gongzuo the Qianniubeishen＂. In this paper, based on previous studies and newly discovered materials, Li Gongzuo's personal life has been re-investigated. Starting with ＂Qianniubeishen＂, through the analysis and comparison of official position, age, relationships, family religion and other aspects, especially the revealing of the relationship between Li Gongzuo and Xue Ping, ＂the legendary novel author Li Gongzuo＂ is proved actually to be the same person as ＂Li Gongzuo the Qianniubeishen＂, which solved the long-time-unknowed mystery of Li Gongzuo's life.
