Guo Jia
Around the time, Cao Cao had a brilliant adviser, Xi Zhicai (), 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 () in the army of Cao Cao, who then held the position of Minister over the Masses () in the Han imperial court.
