Upon learning of Yu Jin's defeat, Cao Cao felt that the Han imperial capital, Xuchang, was too near enemy territory, so he considered moving the capital further north into Hebei. Sima Yi and Jiang Ji said: "Yu Jin's defeat was not due to flaws in our defences, nor would it significantly affect us. Moving the imperial capital is showing our weakness to the enemy. It will cause panic in the regions around the Huai and Mian rivers. Sun Quan and Liu Bei seem close to each other, but they actually don't trust each other. Sun Quan will feel very uneasy upon seeing Guan Yu's victory, so we should incite him to attack Guan Yu's base in Jing Province. This will lift the siege on Fancheng." Cao Cao heeded their advice. Sun Quan later sent his general Lü Meng to attack Gong'an County and invade Jing Province in the winter of 219–220. Guan Yu was captured and executed by Sun Quan's forces.
