This paper describes the historical situation from the end of the Eastern Han Dynasty to the beginning of the Western Jin Dynasty 105, mainly describing the war, reflecting the story of the warlord scuffle at the end of the Eastern Han Dynasty, the political and military struggle among Wei, Shu and Wu countries, and finally Sima Yan unified the three countries and established the Jin Dynasty.

On a broad background, a magnificent war scene was staged. Luo Guanzhong, the editor, integrated the thirty-six strategies of Sun Tzu's Art of War between the lines, including both the plot and the strategy of Sun Tzu's Art of War.
