Guo Jia, courtesy name Fengxiao, was an 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.

Lü Bu, courtesy name Fengxian, was a Chinese military general, politician, and warlord who lived during the late Eastern Han dynasty of Imperial China. Originally a subordinate of a minor warlord Ding Yuan, he betrayed and murdered Ding Yuan and defected to Dong Zhuo, the warlord who controlled the Han central government in the early 190s. In 192, he turned against Dong Zhuo and killed him after being instigated by Wang Yun and Shisun Rui, but was later defeated and driven away by Dong Zhuo's followers.
