The Hongshan culture (simplified Chinese: 红山文化; traditional Chinese: 紅山文化; pinyin: Hóngshān wénhuà) was a Neolithic culture in northeastern China. Hongshan sites have been found in an area stretching from Inner Mongolia to Liaoning, and dated from about 4700 to 2900 BC.
The culture is named after Hongshanhou (simplified Chinese: 红山後; traditional Chinese: 紅山後; pinyin: Hóngshānhòu), a site in Hongshan District, Chifeng. The Hongshanhou site was discovered by the Japanese archaeologist Torii Ryūzō in 1908 and extensively excavated in 1935 by Kōsaku Hamada and Mizuno Seiichi.
Yangshao culture was in the larger area and contemporary with Hongshan culture (see map). These two cultures interacted with each other.
Hongshan burial artifacts include some of the earliest known examples of jade working. The Hongshan culture is known for its jade pig dragons and embryo dragons. Clay figurines, including figurines of pregnant women, are also found throughout Hongshan sites. Small copper rings were also excavated.
The archaeological site at Niuheliang is a unique ritual complex associated with the Hongshan culture.
Excavators have discovered an underground temple complex—which included an altar—and also cairns in Niuheliang. The temple was constructed of stone platforms, with painted walls. Archaeologists have given it the name Goddess Temple due to the discovery of a clay female head with jade inlaid eyes. It was an underground structure, 1m deep. Included on its walls are mural paintings.
Housed inside the Goddess Temple are clay figurines as large as three times the size of real-life humans. The exceedingly large figurines are possibly deities, but for a religion not reflective in any other Chinese culture.
The existence of complex trading networks and monumental architecture (such as pyramids[example needed] and the Goddess Temple) point to the existence of a "chiefdom" in these prehistoric communities.
It has been suggested that religious sacrifice might have been performed within the Hongshan culture.
Just as suggested by evidence found at early Yangshao culture sites, Hongshan culture sites also provide the earliest evidence for feng shui. The presence of both round and square shapes at Hongshan culture ceremonial centers suggests an early presence of the gaitian cosmography ("round heaven, square earth").
Early feng shui relied on astronomy to find correlations between humans and the universe.
Development of Chinese civilization
Some Chinese archaeologists such as Guo Da-shun see the Hongshan culture as an important stage of early Chinese civilization.  Whatever the linguistic affinity of the ancient denizens, Hongshan culture is believed to have exerted an influence on the development of early Chinese civilization. The culture may also have contributed to the development of settlements in ancient Korea.
