According to the Records of Qingyang Prefecture, Qingyang is located in the middle reaches of the Yellow River, which is the cradle of the Chinese nation and has a very complicated experience in the long history of our country. 200,000 years ago, people worked and lived here. According to Fan Wenlan's General History of China, dogs are the totems of dogs, cows are the totems of Qiang people, and tigers, dragons and raccoons are the totems of the Yellow Emperor. Perhaps it is because this region has a long and profound civilization. When the ancient cultures in other regions were covered up by later generations, they were fortunately forgotten because of the transfer of economic and cultural centers and traffic congestion.
