Longshan culture
The area of present-day Jinan has been inhabited for more than 4000 years. The Neolithic Longshan culture was first discovered at Chengziya to the east of Jinan (Zhangqiu District) in 1928. One of the characteristic features of the Longshan culture are the intricate wheel-made pottery pieces it produced. Most renowned is the black "egg-shell pottery" with wall thicknesses that can go below 1 millimeter.
