In 1997, the Laohekou Municipal Museum carried out there rescuing excavation of eight tombs, which fall into two categories:earth-pit tombs and brick-chambered ones. The former are all rectangular shafts, with a slanting passage built in a tomb; the latter have chambers built of long narrow bricks in rectangular earth-pits. The funeral objects include the pottery mao cauldron, double-eared jar, ding tripod, granary, stove, well,pigsty and mill models, jar, zun vase and dog, the bronze belt-hook and coin and iron fu cauldron and knife. In the light of their shape, the combination of their funeral objects and the evolution of these grave goods, the tombs can be divided into two phases: the mid and late Western Han and the Eastern Han.Their rank and the number of their funeral objects suggest that the tomb-owners must have belonged to the common people or petty landlords. The excavation provided new data for studying the amalgamation of the northern and southern cultures in the Han period.展开更多
