Yuan Xi
After his defeat at Guandu, Yuan Shao became dispirited and uninterested in politics. That was until his eldest son Yuan Tan brought 50,000 men from Qing Province, second son Yuan Xi brought 60,000 men from You Province, and nephew Gao Gan brought 50,000 from Bing Province. Yuan Shao prepared to face Cao Cao again after assembling the new reinforcements, and brought the total of some 300,000 men to camp at Cangting. Cao Cao marched his force nearby and faced the challenge.
