or Lung-shan culture
(2500–1900 BC) Neolithic culture of China's Huang He (Yellow River) valley.
Large sites with rammed-earth walls have been found. Characteristic Longshan pottery has thin walls and is well crafted; there are tall-stemmed black cups with eggshell-thin walls as well as polished black beakers. Oracle bones were used for divination. There is evidence of differentiation in social status, and jade artifacts and traces of metallurgy have been found.
