The 2016–2018 excavation of the cemetery at the Sunjiagang site, Lixian County, Hunan

Hunan Provincial Institute of Cultural Relics and Archaeology excavated at the site of Sunjiagang during 2016–2018 after 33 earthen pit tombs were uncovered in 1991. It yielded 192 pit tombs and one urn burial along with a number of pottery vessels and jade artifacts. The whole cemetery was laid out with a clear pattern of spatial arrangement, organized in an orderly style. A unique burial practice prevailed in the cemetery, for which the deceased was laid upon a layer of grave goods. According to the typology of unearthed pottery vessels and jade artifacts, the cemetery at the Sunjiagang site dates sometime from 2200 to 1800 BCE. It represents a new local variant of the Xiaojiawuji culture, and thus can be named the Sunjiagang type culture.
