Wang Can
In the fifth century, Pei Songzhi annotated the "Sanguozhi" by incorporating information from other sources to Chen Shou's original work and adding his personal commentary. Some alternative texts used in the annotations to Lü Bu's biography include: "Yingxiong Ji" ("Chronicles of Heroes and Champions"), by Wang Can; "Xiandi Chunqiu" ("Chronicles of Emperor Xian"), by Yuan Wei; "Wei Shi Chunqiu" ("Chronicles of the Ruling Family of Wei"), by Sun Sheng; "Cao Man Zhuan" ("Biography of Cao Man"), by an unknown writer.
