Chahai is the name of an archaeological site in China, near Fuxin in Liaoning Province, Manchuria, and belonging to the early Neolithic Xinglongwa culture. Dated between 5712-5530 BC, Chahai was a small (about eleven houses) early farming community, although only stone tools support this identification. Hypothesized to be the ancestors of the Hongshan (or Jade Dragon) culture.

(Hongshan culture: Late Neolithic period [4700-2920 B.C.] culture in China, primarily the Manchurian area including Liaoning province and Inner Mongolia; known for ceremonial complexes, jade, coper, perhaps bronze working. )

These ruins lie 2.5 km southwest of Chahai Village which is under the jurisdiction Fuxin 25km away.  The ruins are an open terrain surrounded by mountains.   The world’s oldest jade articles and China’s earliest stone-laid dragon designs were excavated there.  A 19.7 meter dragon is believed to be 8,000 years old.  Jade ware, pottery, and other cultural relics form the foundations of the “Jade Dragon Culture” at Red Mountain.
