Yao Shunyu lived before Xia Dynasty, when China was still in primitive society and belonged to an unwritten history. Annals of Bamboo Scripts was written in the middle of the Warring States Period, and Historical Records was written in the period of Emperor Wu of Han Dynasty, referring to many historical materials in the Spring and Autumn Period and the Warring States Period. That is to say, bamboo annals? This is similar to the writing background of Historical Records, but it is still a thousand years away from Yao Shunyu's time.
There are few written records in the Xia, Shang and Zhou Dynasties, so when Yao Shunyu was written thousands of years ago, both the chronology of bamboo books and historical records were inevitably based on folk rumors and their own imagination, so it was inevitable that it was somewhat different from the real history.
At that time, Yao Shunyu was in a primitive society, and its productivity and social system were very backward. Yao Shunyu, on the other hand, is not the kind of god-given emperor, but the leader of the tribal alliance. They have more power than ordinary people and can get some resources first, so their living standards are slightly better. The leader of the tribal alliance is not the hereditary official position of his father, but the best person elected by each tribe. Therefore, it is very likely that Shun was actually the leader elected by various tribes, instead of accepting Yao's demise.
Although it is recorded in the history books, there are still some discrepancies between the history that actually happened thousands of years ago and the history recorded in the books. Therefore, it is a long road to constantly revise history.
