Pieces of coffins made of valuable and rare Nanmu wood, as well as pottery and iron items, were seen scattered across an area of 1,000 square meters at the ravaged tomb site, located in Gucheng town in Gaochun county of Nanjing, the provincial capital, adjacent to the construction site of an expressway. Judging from some of the items left by the robbers, Puyang Kangjing, a history scholar at the local museum, said Wednesday that the tombs date from the Han Dynasty (206 BC-220 AD).
