Before Chibi, Cao Cao had great advantages: first, Cao Cao "held the emperor to make princes", and it was difficult for princes to compete morally; Second, Cao Cao went south with his newly won army, full of energy. Third, Cao Cao's strength is several times that of Sun and Liu. Since Cao Cao has such advantages, Sun Liu's record is even more brilliant. In this battle, Sun played an important role in the water war and skillfully attacked it with fire, which can be said to be a decisive and famous war example in the history of China. After Battle of Red Cliffs, Cao Cao returned to the north, and there was no chance to go south to Jingzhou on such a large scale. Cao Cao Group also lost the possibility of unifying the whole country in a short time.
Zhou Yu and others confronted Coss across the river and sent Gan Ning to attack Yiling (now Yichang, Hubei). Coss led troops into this area, and Zhou Yu led troops to rescue them. Liu Bei returned to Xiakou, wanted to return to Hanshui, and went around behind Coss. The following year, Coss was forced to withdraw. Sun Quan continued to form an alliance with Liu Bei to jointly resist Cao Cao. Liu Bei took advantage of the situation to acquire most of Jingzhou, including Wuling (county in Changde, Hunan), Changsha, Guiyang (county in Chenxian, Hunan) and Lingling (all in Hunan). Later, he won Yizhou in Liu Zhang. Sun Quan occupied Jiangdong, forming a separatist situation of Wei, Shu and Wu.
