Xun You
Chen Shou, who wrote Fa Zheng's biography in the "Sanguozhi", appraised Fa as follows: "Fa Zheng clearly foresaw success and failure hence he conceived brilliant strategies and plans for his lord however he was not known to be of good moral character. In comparison with officials from (Cao) Wei, if Pang Tong was akin to Xun Yu and Xun You then Fa Zheng should be comparable to Cheng (Yu) and Guo (Jia)."
