Nihewan and Zhoukoudian are important areas where early humans and cultures originated and reproduced in northern China and even East Asia. Geologically, both site groups belong to the Haihe River valley; chronologically, the Nihewan sites date to ca. 1.7 million years ago, and the Zhoukoudian sites date to ca. 0.5 million years ago; and culturally, both are dominated by the small-flake-tool culture. Thus, it is speculated that the early culture in the Zhoukoudian sites came from the migrants from the Nihewan Basin who facilitated cultural diffusion in the area; in turn, it also affected the culture in the Nihewan area during the subsequent development. This paper proposes the development path of the Paleolithic culture in northern China, that is, early humans in this region roughly experienced three stages of subsistence from lake-dependent to cave-dependent and then to river-dependent.
