In 220, Cao Cao died of illness, and his son, Cao Pi, abolished Emperor Xian of Han Dynasty and became emperor on his own, with the title of Wei and its capital in Luoyang.

In the second year, Liu Bei also proclaimed himself emperor in Chengdu, with the title of Han, which was called by history. In 222, in order to recapture Jingzhou, Liu Bei mobilized all the troops and personally recruited Wu Dong. As a result, Wu Dong was defeated in Xiaoting and fled back to Bai Di to die.

The tripartite confrontation between the three countries has been fully formed.
