There were many countries in the ancient history of the mainland, and now they all appear in the textbooks of the mainland, as chinese people, we should know some things that have happened in our own country, but from Yao to Qing, there are many unknown things that have not been recorded during this period, so they will disappear into the long river of history. There are many things that we do not know in addition to this, such as in history textbooks, the first dynasty on the mainland was the Xia Dynasty, at that time, because the earliest dynasty found in the cultural relics unearthed in the past was the Xia Dynasty, and at that time, archaeologists also doubted the uniqueness of the Xia Dynasty, but with the development of human civilization and the exploration of history, a dynasty suspected to be older than the Xia Dynasty was found, which made people have a new view of history.
???
According to the clues provided by some scholars, we learn that the new dynasty existed at least a thousand years before the emergence of the Xia Dynasty, which they called the Yu Dynasty. At that time, there seemed to be a record of the Yu Dynasty in the "Zuo Zhuan", but we could not be sure of his authenticity, nor could we let history confirm its existence, but the new face of history that has been displayed now has directly pushed forward the course of history by more than a thousand years, so it can now be said that China has a historical civilization of 6,000 years. Of course, this view has not yet been universally recognized, because it is really a long time ago, and people at that time did not know whether they had used the trajectory of their lives as evidence of historical remains to prove their existence, but in history, clues about this dynasty can be found, so for the Yu Dynasty, its mystery is still impossible to unveil for the time being.
We once mentioned the existence of the Yu Dynasty in "Han Feizi Xianxue", "Yu Xia for more than 2,000 years", and the "Xia" in it of course refers to the Xia Dynasty, and the conjecture of this "Yu" people is the Yu Dynasty. Through the history of the Xia Dynasty, the Xia Dynasty existed for 471 years, and according to the book, the Yu Dynasty existed for more than 1600 years! It feels as novel as discovering a new continent. Some people deny the existence of the Yu Dynasty, but there is no way to explain the old saying in "Han Feizi", but if the Yu Dynasty really existed for 1600 years, how did people sometimes live? What does society look like? How did people spend their long years? Therefore, many scholars still do not agree with such a statement.
There are also some documents that mention that Shun was the king of the Yu Dynasty at that time, but in our understanding of history, he seems to be a god-like being and cannot be a real representative figure, so this is also a strong support point of view for the opposition. Although there is indeed no evidence to prove its existence, it cannot be denied, after all, there are still many new things in the world waiting for people to discover and explore.
