Xingan , sometimes Dayangzhou (大洋洲), is an archaeological site located on the Gan River in Dayangzhou, Xingan County, Jiangxi, China. The site was excavated in 1989, and it dates to around 1200 BCE. The rich offerings of bronze and jade objects made it the second richest burial site known after the Fu Hao's tomb.
Xingan was home to a rectangular tomb covered by a tumulus. Largely damaged by the sand shifts, it did not preserve the skeletal remains of coffin, making some archaeologists doubt that the find was a tomb at all.
Over 1,000 jade artefacts were discovered at Xingan.
Xingan is known for its unique style of bronze vessels, with 54 being discovered; over 480 bronze objects were uncovered at the site. The bronze casters at Xingan copied and mastered the techniques of the Erligang culture, then localized the bronze vessels in a distinct style. Xingan is associated with the Wucheng culture.
The artefacts from Xingan are housed primarily in the Jiangxi Provincial Museum.
