How many years is the history of Chifeng?

Chifeng City is located in the southeast of Inner Mongolia Autonomous Region, at the junction of Mongolia, Hebei and Liaoning provinces, with a total area of 90,000 square kilometers, jurisdiction over 3 districts, 7 flags and 2 counties, and a total population of 4.6 million, making it the most populous city in Inner Mongolia. Chifeng, with a history of 10,000 years of human civilization, is one of the birthplaces of Chinese civilization.

The type of primitive human culture named by the national archaeological community in China is Xinglongwa Culture in the early Neolithic period from 8 150 to 7350. 7 150 ~ 6420 Zhaobaogou culture in the middle Neolithic period; Hongshan Culture in the middle and late Neolithic period from 6660 to 4870; Fuhe culture in the late Neolithic period, 5300 years ago; Xiaoheyan culture in the late Neolithic period from 5000 to 4870; Xiajiadian Lower Culture in Late Neolithic Age and Early Bronze Age in North China from 4500 to 4200 years ago. Archaeological excavations of stone tools, bone tools, pottery, bronzes and other production and living utensils prove that our primitive ancestors had lived a primitive life of farming, fishing and hunting and animal husbandry as early as 8,000 years ago. In the 1970s, the large jade dragon unearthed more than 5,000 years ago in Sanxingtala, Onniute Banner caused a sensation in the whole country and was known as "Yi Long in the world". It is proved that the ancient culture in Chifeng, like the Central Plains, is one of the important sources of ancient civilization in China. [
