This land with ravines and ridges, barren land and ten years and nine droughts has been inhabited by human beings since the Neolithic Age. Because it is located on the edge of the desert, it is a border area that rejects the Xiongnu in the north and defends the Guanzhong, the hometown of the emperor in the south.

On the basis of the original culture, it absorbed the Central Plains culture, Chu culture and red culture, and formed a unique northern Shaanxi culture.
