The semi-circular wooden coffin cover from the Qin tombs at the Shuihudi site in Yun-meng is not found in Chu tombs or later Chu cultural areas.By collecting relevant burial data and trac-ing their origins,some round wooden coffin covers from Eastern Zhou tombs in Lingtaidong Mountain and Shijia cemetery in Qingyang of Gansu Province are similar to the semi-circular wooden coffin cov-ers from the Shuihudi site,possibly suggesting a connection.These were used only by government offi-cials and nobles,likely representing a diverse group of people from various local origins.The coexis-tence of the semi-circular wooden coffin covers and sacrificial burials at the Shuihudi site suggests a temporal and spatial relationship.The introduction of sacrificial burials and semi-circular wooden coffin covers to the Chu region likely came from Qin immigrants from the Guanlong region.
