Extended data:

The influence of the dispute between Chu and Han

The dispute between Chu and Han directly evolved from the peasant war at the end of Qin dynasty, but its nature was completely different. Under the social conditions at that time, although the peasant war successfully overthrew the old feudal dynasty, Liu Bang and Xiang Yu, the former leaders of the peasant war, had to take the old road of feudal rule and turned into contenders for feudal sovereignty.

In this competition, Xiang Yu had a strong sense of old nobility, was not good at employing people, and could not rebuild the unified dynasty. Knowing that people are good at their duties and taking advantage of the situation, Liu Bang finally defeated Xiang Yu, ascended the throne of the Western Han Emperor and established the Han Dynasty.

The Theme Source of Romance of the Three Kingdoms

The History of the Three Kingdoms, written by Chen Shou in the Western Jin Dynasty, is the earliest source of the story of the Three Kingdoms, but it is a biographical history book with a brief record and an outline. Pei Songzhi, a native of the Southern Song Dynasty, added many anecdotes to Notes on the History of the Three Kingdoms, which greatly enhanced the legend and readability.

Liu Zhixi, a historian in the middle Tang Dynasty, said in Shi Tong that the story of Zhuge Liang's death has been "learned from his journey and spread to many people", which shows that the story of the Three Kingdoms has been widely spread among the people during this period. There is a poem in Li Shangyin's "Pride of Children" in the late Tang Dynasty, which shows that the story of the Three Kingdoms was known to women and children at the latest in the late Tang Dynasty, and the story of the Three Kingdoms became more popular in the Song Dynasty through artists' performances and rap, which has shown a distinct tendency of "respecting Liu and belittling Cao".

The stories of the Three Kingdoms in the Jin and Yuan Dynasties were put on the stage in large numbers, and there were also many stories of the Three Kingdoms in school books and dramas. According to Ghost Record and Taihe Yinzhengpu, there are nearly 30 kinds of works telling the story of the Three Kingdoms in Yuan Zaju alone. The Jin Dynasty recorded in the Record of Dropping Out of Farming includes Xiangyang Hui, Liu Bei, Lu Bu and Battle of Red Cliffs.

During the period from Yuan Yingzong to Zhi Zhi (1321-1323), A Commentary on the Three Kingdoms published by Xin 'an Shi Yu came out, which was the earliest and only commentary on the story of the Three Kingdoms.
