The Romance of the Three Kingdoms began at the end of the Yellow Turban Uprising in the Eastern Han Dynasty and ended at the beginning of the Western Jin Dynasty when the country was reunified. With the formation and evolution of the three political and military groups of Wei (Cao Cao), Shu (Liu Bei, Zhuge Liang), and Wu (Sun Quan), the shield struggle was the main line. In the end, the replacement of Wei, Jin, unified the whole country, and the country was unified again.
