Peiligang culture was named after being discovered in Peiligang, Xinzheng city, Henan province. Dating back to 7,000 to 9,000 years ago, Peiligang culture was primarily scattered in the central part of Henan province. During that period, Chinese ancestors began to live in clan settlements, practiced collective burials, and led a relatively egalitarian tribal community life. A means of subsistence that combines fishing, hunting and farming developed and primitive beliefs emerged.
