In 2001, the Gansu Provincial Institute of Cultural Relics and Archaeology excavated the site at Luotuocheng in Gaotai County and four groups of tombs in the vicinity. The present paper reports Tomb M2 among the earth-mounded graves and M1, M4 and M5 in the southern tomb group. M1 and M2 are multi-chambered brick tombs, and either of them consists of a barrow, a passage, a screen wall, a corridor and chambers. No information on the coffins was obtained owing to robbery. M1 is poor in funeral objects; M2 yielded mainly pottery, including drooping-curtain design jars, string pattern jars, basins, and three-legged dishes. Small-sized pictorial bricks were found in M2, each representing a scene of husbandry. M4 and M5 are conglomerate-cut single-cave tombs. Either has a subrectangular chamber, with the coffin in a good condition. The funeral objects are rare, mainly wood-ware, such as tomb figures and horses, dishes, ladies, eared cups, and inventories of grave goods. Judging by the tomb structure and funeral objects it can be inferred that M1 and M2 are earlier in date, going back to the Wei-Jin period, while M4 and M5 should be assigned to the Sixteen Kingdoms period. The owners of the former two must have held a certain position in both social and economic aspects, whereas those of the latter two belong to the poor people.
