龙山文化
The Yueshi culture () was an archaeological culture in the Shandong region of eastern China, dated from 1900 to 1500 BC. It spanned the period from the Late Neolithic to the early Bronze Age. In the Shandong area, it followed the Longshan culture period (c. 2600–1900 BC), and was later replaced by the Erligang culture (identified with the historical Shang dynasty).
