Abstract: The Kehe sites may be older than the Sinanthropus site, and the formers seem to be nearer to the Gongwangling site in climatic environment as viewed fron mammalian faunas.
Techno-typologically the Kehe industry bears a relationship to the Sinanthropus one though there are some distinct differences among them. However the primitiveness of the Kehe industry is not evident.
