They are: Wei State (rulers are Cao Cao, Cao Pi, Cao Rui), Shu State (rulers Liu Bei, Liu Chan), Wu State (Sun Quan).
The Three Kingdoms (220-280) was a historical period that extended from the Eastern Han Dynasty to the Western Jin Dynasty. It was divided into three regimes: Cao Wei, Shu Han, and Soochow. During the Battle of Chibi, Cao Cao was defeated by the coalition forces of Sun and Liu, laying the foundation for the Three Kingdoms.
In 263, Sima Zhao of Cao Wei launched a war between Wei and Shu, and the Shu Han Dynasty was destroyed. Sima Zhao died of illness two years later. His son Sima Yan deposed Emperor Yuan of Wei and established his own country. The founding name was "Jin" and it was called the Western Jin Dynasty in history. In 280 AD, the Western Jin Dynasty destroyed Dongwu and unified China. This ended the Three Kingdoms period and entered the Jin Dynasty. Extended information

The artistic achievements of "The Romance of the Three Kingdoms" are more important in its military and political description and character creation. Novels are best at describing wars and can describe the characteristics of each war. Pay attention to describing the use of different strategies and tactics under specific conditions, and guide the display of subjective initiative in combat, instead of spending the main text on pure strength and martial arts competition.
