A Neolithic village site, now preserved as a museum, at Zhengzhou in China. Several Yanshao levels are overlaid by Hougang II and Shang remains; radiocarbon dates range from c 3700-3050 BC. The uppermost Yanshao level is a late stage of the Miaodigou I culture; the expected painted pottery is found alongside unpainted pots, including ding and dou shapes, that recall the Huating-Dawendou phase of the Qinglin'gang culture. This pottery may represent the beginnings of a westward movement of east-coast influences that eventually transformed the Yangshao tradition, giving rise to the Hougan II culture.
