The reason why Ningxia is a fruitless city for Hui Han is the wide gap between the poor and the rich. Ningxia is very remote and the economic situation is not very good. Ningxia is one of the birthplaces of the ancient civilization of the Chinese nation. As early as 30,000 years ago in the Paleolithic Age, there were human beings living and reproducing here. In 1038 A.D., Li Yuanhao, the leader of the Danghang tribe, established the Xixia Dynasty here and formed the Xixia culture. The Shuidonggou site in Ningxia is a Paleolithic site from 30,000 years ago. Ningxia refers to the Ningxia Hui Autonomous Region, which is a provincial administrative region of China. Ningxia Hui Autonomous Region, abbreviated as Ning, has its capital Yinchuan. It is located in the middle and upper reaches of the Yellow River in northwestern China.
