It has an earth-rammed mound at the top and a sloping tomb-passage at the southern end. In the pit is a circle of stone wall, the gap outside which is filled with charcoal, and the tomb bottom is covered with stoneslabs. The room within the walls is divided into two parts: the frontal for funeral objects and the rear for a wooden chamber and the coffin it encases. The chamber is triplex, built of narrow blocks of wood; the coffin, double, with the boards mortised together. Of the funeral objects, despite serious robbery, there remain jades, bronzes, irons, lacquered articles, and a number of “wu zhu” coins.Judging from the characteristic features of the tomb shape and grave goods, the tomb can be dated to the late Western Han period.展开更多
