Anyone who has received compulsory education should know that the earliest dynasty in China was the Xia Dynasty. Because that's what history textbooks say. However, after all, history is written by later generations, and posterity does not know about the previous things, so most of the history of a long time ago belongs to the element of speculation. At present, it is believed that the Xia Dynasty, as a formal class dynasty, dates back about 4,000 years, and the history before the Xia Dynasty is collectively referred to as the Mythical Age. However, in some ancient books, it is recorded that a dynasty before the Xia Dynasty was Tang Yu. For example, Sima Qian's "Records of History" has a record of Tang Yu: "Shi Ji Zheng Lie's biography" "Your Majesty has many desires inside and benevolence outside, but he wants to emulate Tang Yu's rule!" ”
I believe that although you don't know the Tang Yu Dynasty, you should have heard of the ancient Chinese mythological figures, Yao, Shun, And Yu, these three famous figures. The full names of the three of them were Tang Yao, Yu Shun, and Dayu. And Tang Yu is the combined name of Tang Yao and Yu Shun. The third character is the character of Dayu Zhishui, which will not be said more today, they all existed in the same period.
Although the history textbooks do not mention the Tang Yu Dynasty, but there have indeed been relevant stories about Yao, Shun, and Yu, the reason why this dynasty is not counted as a dynasty like the Xia Dynasty is because it is believed that the characters of the Yao Shun Yu period before the Xia Dynasty are primitive tribes, like primitive people, there is no civilization, so some people say that according to historical records, the history of Chinese civilization should be counted from the Xia Dynasty, which is 4,000 years. However, this is not the case, during the Yao Shunyu period, there was already enough civilization, and the degree of civilization was not low. The simplest is the example of Dayu zhishui, there is not enough civilization, how can we control water?
In addition, that period can be considered as an era of coexistence between man and god, so China's traditional culture, such as the Five Elements Bagua, Yin and Yang Taiji, Chinese medicine, I Ching, etc., is not written by posterity, but is passed down by posterity. Therefore, that period was actually a highly civilized civilization, with some civilizations in the heavens. Therefore, those ancient myths and legends also have some authenticity. So it was also a fantastic and beautiful historical period.
