In 1991, the Yunnan Provincial Institute of Cultural Relics and Archaeology, in co-operation with other institutions, carried out the secondary excavation in the Jiangchuan Lijiashan cemetery. The 60 excavated tombs are all earth-pit graves without clear data on coffins and fall into three types: large-, medium- and small-sized. Among the grave goods are bronzes, irons, gold- and silver-wares, jade, agate and other precious stone artifacts, bamboo articles and wooden objects. The bronzes and irons include mainly implements of production and weapons, and also instruments of funeral ritual. According to the stratigraphical evidence of the cemetery and changes in the combination of funeral objects, the tombs can be divided into four phases. The first phase contains 28 mediun and small-sized tombs with irons as the main grave goods and without bronze-and-iron compound objects, and goes back to the mid Western Han period, prior to Wudi's reign. The second phase is represented by Tombs M47 and MS1, both furnished with a second-tier platform and containing a two-person joint burial. The large-sized tomb yielded bronze weapons, hoes, spades, and a tomb-figurine of a male holding an umbrella. The medium and small tombs are furnished chiefly with bronzes, and also a few bronze-and-iron compound articles. They date from the mid and late Western Han period. The third phase is represented by Tomb M82 and features the increase of bronze-and-silver ware. The large-sized tomb contains less bronze-ware; in the medium and small graves, bronze-and-iron ware, irons, horse trappings and lacquer-ware occur commonly. They can be assigned to the time from the late Western Han to the early Eastern Han period. The fourth phase comprises only three tombs, M49 and other two. Their funeral objects feature the sharp discrease of Dian-style articles and the emergence of Han-style objects,such as fu cauldrons, zeng steamers and incense burners. They go back to the earlier Eastern Han period.
