The tomb is located inside the water turbine factory compound in Mashi Village, Shengfang Town. It was uncovered during the construction work for industrial park expansion. The mound covering the tomb is large and magnificent, with a soil layer as thick as 13 metres and an area exceeding 200 square metres.
This burial site dates back to the Western Han Dynasty. A wealth of burial objects were unearthed, including a golden official seal and five pottery tripods. These relics not only testify to the high social rank of the tomb owner, but also provide extremely valuable physical evidence for the research of local history of the county. According to preliminary textual research, the occupant of the tomb was Liu Cang, Marquis of Ancheng.
