Longshan culture
Archaeologists have divided the culture into five phases, corresponding with the late stage of the Longshan culture, the early, middle and late stages of the Erlitou culture and the early stage of the Erligang culture. The early phase of the culture was influenced by the Longshan culture, while the middle phases were influenced by the Qijia culture; it was during this time frame when bronze artefacts begin to appear in the material culture. At this point Zhukaigou people were agriculturalists, with millet as a main staple, they also had sheep, pigs, and cattle.
