Pei Songzhi
The only extant historical source about Jiang Gan's life is the "Jiang Biao Zhuan" (江表傳). In the fifth century, Pei Songzhi added excerpts from the "Jiang Biao Zhuan" in his annotated version of the third-century historical text "Records of the Three Kingdoms" ("Sanguozhi") by Chen Shou.
