As spring arrives, the Qingdun Neolithic Site in Nantong, East China's Jiangsu province, is beginning to turn yellow and green. 

Located in Qingdun village, Nanmo town, Hai'an, the Qingdun Neolithic Site was included by the State Council in the sixth list of cultural relics under national protection in 2006.

Covering an area of about 70,000 square meters, the site is the largest and best-preserved Neolithic ruin in the eastern Jianghuai (the Yangtze and Huaihe rivers) area.

The site was discovered and excavated in the 1970s and shows evidence of civilization in the Jianghuai area 3,000 years earlier than previously thought.

The site is surrounded by water and is home to Qingdun Culture. It has a large number of cultural relics and is considered the origin of Jianghuai Culture.
