Guo Jia

Guo Jia (pronunciation^ⓘ) (170– c.October 207), courtesy name Fengxiao, was a military adviser to the warlord Cao Cao during the late Eastern Han dynasty of China. Throughout his 11 years of service, Guo Jia aided Cao Cao greatly with his brilliance and foresight, and his strategies were instrumental to Cao Cao's triumphs over rival warlords such as Lü Bu and Yuan Shao. For example, four years before Cao Cao's decisive victory over Yuan Shao at the Battle of Guandu, Guo Jia already foresaw that Cao Cao would win when he pointed out ten advantages Cao Cao had over Yuan Shao.

The authoritative historical source on Guo Jia's life is the Records of the Three Kingdoms (Sanguozhi), which was written by Chen Shou in the third century. 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 Guo Jia's biography include: Fu Zi, by Fu Xuan; Wei Shu (Book of Wei), by Wang Chen, Xun Yi and Ruan Ji; Shiyu (Accounts of this Generation), by Guo Song.

Guo Jia was from Yangzhai County (陽翟縣), Yingchuan Commandery (潁川郡), which is in present-day Yuzhou, Henan. As a youth, he was famous for his intelligence and foresight. Since reaching adulthood at around the age of 19, Guo Jia had been travelling around the country and befriending members of the scholar-gentry and other talented persons. He did not associate himself with the hoi polloi and was thus not very well known outside of his circles. However, all those who knew him recognised his talent and felt that he was extraordinary. When he was 26, he served in the Han government as a minor official in the office of the Minister over the Masses (司徒).

Guo Jia once travelled to Hebei to meet Yuan Shao, an influential warlord who controlled most of northern China at the time. He later told Yuan Shao's advisers Xin Ping and Guo Tu, "An intelligent adviser should be prudent when he chooses which lord he wishes to serve so that his lord will heed every piece of advice he gives. The adviser can then establish his reputation. Lord Yuan (Yuan Shao) wishes to mimic the Duke of Zhou by recruiting men of talent to serve under him but he does not know how to tap into their abilities. He focuses too much on unnecessary details and neglects the main points; he likes to listen to many ideas but is indecisive. It is difficult for him to save the Empire from its troubles and achieve hegemony over the various warlords!" Guo Jia then left Yuan Shao.

Around the time, Cao Cao had a brilliant adviser, Xi Zhicai (戲志才), whom he appreciated greatly, but Xi died early. Cao Cao told another adviser Xun Yu, "Ever since Xi Zhicai died, I've been lacking someone whom I can form strategies with. I heard there are many talents in the Ru and Ying regions. Who can replace Xi Zhicai?" Xun Yu recommended Guo Jia to Cao Cao. Cao Cao and Guo Jia had a discussion on the affairs of their time, after which the former remarked: "This must be the man who will help me achieve greatness." Guo Jia also happily said, "He's truly the lord I wish to serve." Guo Jia was then appointed as a Libationer (祭酒) in the army of Cao Cao, who then held the position of Minister over the Masses (司空) in the Han imperial court.

The Fu Zi recorded a detailed conversation between Guo Jia and Cao Cao, in which the former carefully pointed out ten advantages the latter had over Yuan Shao. Cao Cao asked Guo Jia, "Benchu (Yuan Shao) rules Ji, Qing and Bing provinces and has vast territories and large numbers of troops under his command. However, he has also been making offensive moves. I intend to attack him, but my forces are weaker than his, so what should I do?"

Guo Jia replied,

"Everyone has heard of the rivalry between Liu Bang and Xiang Yu. Liu Bang won by strategy; Xiang Yu was very powerful but he still lost to Liu Bang. Based on my observations, Yuan Shao has ten disadvantages while you have ten advantages. (Yuan Shao) may have many troops but they are useless.
