This statement is not accurate, there is a liu bei in the royal family tree that is only a deduction, and there is no "uncle Liu Huang" in the history. After Cao Cao defeated Lü Bu in the Romance of the Three Kingdoms, he took Liu Bei back to Xuchang. Emperor Xian ordered Zong Zhengqing to take the genealogy of the clan to check, which said that Liu Bei was after Liu Sheng, the King of Zhongshan Jing. After the genealogy, Emperor Xiandi discovered that Liu Bei was his uncle, so he invited him to the side hall to tell the gift of his uncle and nephew. Since then, people have called Liu Bei Uncle Liu Huang.
However, this statement is obviously very problematic.
According to the Chronicle of the Three Kingdoms, Liu Bei's grandson Liu Zhen (劉贞), the son of Liu Sheng, the Prince of Zhongshan Jing, was created Marquis of Luchengting in Zhuo County in the sixth year of the Yuan Dynasty (117 BC). Later, because of the sacrifice of the Zongmiao Temple, Liu Zhenjin's gold was insufficient and he was stripped of his title, so he lived in Zhuo County.
Sheng Zizhen (胜子贞), Marquis of Lucheng Pavilion in Lucheng County, fengzhuo County in the sixth year of the Yuan Dynasty. Sit on the gold lost marquis, because of the family.
It is very clearly written here that when Liu Sheng's son Liu Zhen was born, Liu Bei's ancestors had already been stripped of their titles, and the so-called Liu Zhen's descendants Liu Ang, Liu Lu, Liu Lian, and others could not have knighthoods.
In addition, in the canonical history, although it is recorded that Liu Bei was after Liu Sheng, the King of Zhongshan Jing, it is not specifically said that there are several generations of descendants, only mentioning that Liu Bei's grandfather was called Liu Xiong and his father was called Liu Hong. There is also no record of the genealogy of the Emperor Cha clan. According to the yanyi, Liu Bei was the eighteenth grandson of Emperor Jing. However, Emperor Xiandi was the thirteenth grandson of Emperor Jing, and in terms of generations, Emperor Xiandi was much taller than Liu Bei, and Liu Bei could not be the emperor's uncle.
Therefore, the so-called Liu Bei is the emperor's uncle in the speech is obviously only a novelist's statement and cannot withstand scrutiny. Of course, although the statement that Liu Bei was an imperial uncle was fabricated, there was little doubt that he was a relative of the Han Dynasty. Although Liu Bei was born poor, the Liu family was also a large clan in Zhuo County, and there were many people in the clan, "Shishi Prefecture County". For example, Liu Bei's grandfather Liu Xiong served as a county commander in Fan County, Dong County. During the Eastern Han Dynasty, a person's origin was very important, and so many people of the Liu clan became officials, and it was obvious that they were the King of Zhongshan Jing, and this statement had been recognized by everyone. Liu Bei's family was poor, or it was caused by the early death of his father, not from a humble origin, otherwise it would be impossible to worship the famous scholar Lu Zhi as a teacher later.
Moreover, on the other hand, since Liu Bang established the Western Han Dynasty, it has lasted about four hundred years to the end of the Eastern Han Dynasty. After four hundred years of life and reproduction, the Han dynasty relatives are already a very large group.
At the end of the Eastern Han Dynasty, there were not a few Liu clan relatives who were active in the political arena, and the more famous ones were Liu Yu of Youzhou, Liu Yan of Yizhou, Liu Biao of Jingzhou, Liu Miao of Yangzhou, Liu Ye of Cao Cao, and so on. Even under Liu Bei's command, there was a Liu Yan from the Han Dynasty who followed him for a long time.
Therefore, the sign of the Han Dynasty Patriarch is not as appealing as in the interpretation. Liu Bei can achieve a career, mainly because he has excellent ability, relying on his own efforts in exchange, there is no need for too much impersonation.
Therefore, when Cao Cao and Liu Bei fought, they would scold Liu Bei for being a "seller of shoes", but did not mention whether he was a relative of the Han Dynasty, because there was really nothing to question.
