Why is Yuncheng called the birthplace of ancient civilization in China?

Yuncheng has another name, Hedong. There is a saying that goes like this? Look at the century-old history of civilization in Shanghai, the thousand-year history of civilization in Beijing, the three-year history of civilization in Xi and the five-year history of civilization in Yuncheng. Yao Shunyu, one of the three emperors and five emperors in ancient China, lived in Yuncheng at that time. There is also a Dayu crossing in Ruicheng County, Yuncheng. It is said that Dayu lived there when he was harnessing water. The Yellow River is the mother river of China, and Yuncheng is located around it. China, a towering tree, grew up on this land. The geographical location of Yuncheng is very good. Different from other cities in Shanxi, it has no mineral resources and the terrain is also a basin. Basically, I have not encountered any devastating disasters, and most of the food can be self-sufficient. So in today's China, Yuncheng is really developing slowly, only a fourth-class city, and basically develops some coastal cities. So in some difficult areas, Yuncheng has been thrown here, it doesn't matter. At the beginning, China was born. Yuncheng has thousands of cultural attractions, and traces of history can be seen everywhere. Therefore, if you want to know more about historical figures, you can visit Yuncheng, such as Guandi Temple, Dayudu, Guanquelou, Lijia Courtyard and Wang Jia Courtyard. Guandi Temple is a famous military commander Guan Gong. Bian Xiao was lucky enough to have been there once. There are also footprints of the master, which are several times larger than ordinary people. Whenever people go there, they compare with their own feet. These buildings are also relatively intact. When they enter, the word history will come to mind. There are also historical figures in Yuncheng, perhaps too far away from now. Yao Shunyu only learned about Yuncheng in textbooks, so even if Yuncheng's cultural background is backward, few people travel every year. Among many cities, Shanxi seems to have no other place to produce coal and vinegar, and Yuncheng has even been forgotten.
