Looking back at the five thousand years of history in China, there are about 409 emperors, each of whom has merits and faults, and have made certain contributions to promoting historical civilization. Most of the founders of dynasties were civilians, full of enthusiasm and ambition, and established their own countries. In the Three Kingdoms era, when there was a dispute between divisions and disputes, the three main regimes were in the hands of Cao Cao, Liu Bei, and Sun Quan.
Liu Bei, the founder of the Shu Han Dynasty, lived in the countryside before, sold straw shoes for a living, and lived a hard life, so his mother let him go out to study, first to learn from the teacher, and then to join many struggle activities, through continuous efforts, he became the founding prince of the Shu State.
We know that Liu Bang of the Western Han Dynasty is the ancestor of Liu Bei, and the Han Dynasty he founded has a history of more than 400 years, it can be said that Liu's status during this period is very high, and Liu Bang, as the founder of the country, is naturally indispensable.
Therefore, at that time, almost all people surnamed Liu wanted to have a relationship with Liu Bang to a greater or lesser extent, including Liu Bei, who called himself "Queen Jing of Zhongshan", which had a good signboard on the road to hegemony, eliminating a lot of resistance for the establishment of the Shu Han regime, after all, the slogans of the Kuangfu Han Room were shouted before.
However, if Liu Bei is really "after the King of Zhongshan Jing", from 154 BC to the end of the Eastern Han Dynasty, there are hundreds of years, and it is reasonable to say that Liu Bei's lineage has been declining for a long time, so why can his identity still be found in the royal family tree? It's actually quite simple.
First of all, in the Qin and Han dynasties, there has been a family tree, and the writing of family trees in the Central Plains is extremely strict, at that time the people who have a family tree are basically some princes and nobles with status, and ordinary people have no family tree at all, because they are not qualified, although the ancestor Liu Bang was a commoner before, but finally became the emperor through hard work, so he created his own family tree.
Secondly, in the feudal society with a clear class system, the imperial court had a person in charge of compiling a family tree, and ordinary people could not write a family tree without authorization, otherwise it was the crime of deceiving the king, so most of the people did not know who their ancestors were. Liu Bang, who naturally changed from a commoner to an emperor, did not know who his ancestors were.
In order not to make Liu Bang angry, those who managed the genealogy made up a very powerful ancestor in history, which also demonstrated to the people who could write the genealogy later, they all drew according to the gourd, first found the place where their family lived earlier, and then linked their surnames with celebrities in that area, and a complete set of genealogies was formed.
Later, not long after Wang Mang usurped the throne and seized power, he was retaken by Liu Bang's descendant Liu Xiu, but in fact, Liu Xiu's status had nothing to do with the imperial family, and Liu Xiu's family when he was a child was poor and relied on the relief of relatives to survive, which shows that Liu Xiu's status at that time was much lower than Liu Bei's.
But even so, as long as he is still a descendant of the royal family, his genealogy will still be written, so Liu Xiu still belongs to the side branch of the royal bloodline, that is to say, he belongs to the royal descendants of the Liu family. From this point to the end of the Eastern Han Dynasty, although Liu Bei has been living in the folk, his identity is likely to be real.
