Regarding the fictional content in the Romance of the Three Kingdoms, for example, the official history did not write about Liu's three marriages in Taoyuan, but only mentioned that he was like a brother. In the official history, the person who "whipped Du You" was Liu Bei. Liu Bei killed Che Zhou in Xuzhou and Cai Yang in the ancient city.
Extended data:
The Romance of the Three Kingdoms, one of China's classical Four Great Classical Novels, is China's first chapter-by-chapter romance novel, written by Luo Guanzhong, a famous novelist at the end of Yuan Dynasty and the beginning of Ming Dynasty. The Romance of the Three Kingdoms describes the history of nearly a hundred years from the end of the Eastern Han Dynasty to the beginning of the Western Jin Dynasty, mainly describing the war, telling the story of the warlord melee in the end of the Eastern Han Dynasty, the political and military struggle between Wei, Shu and Wu, and finally Sima Yan unified the three countries and established the Jin Dynasty.
The story of the Three Kingdoms is widely circulated among the people, but the overall description is sloppy, the words are obscure, the story plot is bizarre, most of them are inconsistent with the official records, and the names and places are full of fallacies. Later, Luo Guanzhong absorbed folklore, scripts and drama stories on the basis of Chen Shou's The Three Kingdoms and Pei Songzhi's Notes, and wrote The Romance of the Three Kingdoms.
