Jiahu - Neolithic culture in China

"Jiahu was the site of a Neolithic settlement based in the central plain of ancient China, near the Yellow River. It is located between the floodplains of the Ni River to the north, and the Sha River to the south, 22 km (14 mi) north of the modern city of Wuyang, Henan Province. Most archaeologists consider the site to be one of the earliest examples of the Peiligang culture. Settled around 7000 BC, the site was later flooded and abandoned around 5700 BC. The settlement was surrounded by a moat and covered a relatively large area of 55,000 square meters. At one time, it was "a complex, highly organized Chinese Neolithic society", home to at least 250 people and perhaps as many as 800. - Wikipedia"
