In Liangzhu Ancient City, burials of different levels followed a strict system in terms of the types and quantities of jade, while in sharp contrast, both elites and commoners used only basic pottery assemblages in their burials. In order to clarify whether there is a difference in the production of burial pottery used by Liangzhu elites and commoners, to explore the role of pottery in the process of Liangzhu's social complexity, and to compare it with the relevant study of the Qujialing culture, this paper selects 201 pieces of pottery samples from the elite cemeteries of Jiangjiashan and the commoners' cemeteries of Bianjiashan in Liangzhu Ancient City, and analyzes them for their chemical compositions by using pXRF. The results show that there is a difference in the origin of the burial pottery used by the Jiangjiashan elites and the Bianjiashan commoners. The burial pottery used by the Jiangjiashan elites was most likely the product of processing for specific funerary events, and the corresponding production activities were controlled by the elites; whereas the burial pottery used by the Bianjiashan commoners came from a high level of specialized production, and there was a differentiation in the production of the vast majority of the coarse paste pottery and fine paste pottery, which should be spontaneous and independent, and the elite did not intervene. Therefore, in addition to jade, the burial pottery used by the Liangzhu elites also served as an expression of their status, i.e., controlling the production of special pottery was one of the means of constructing their identities. This phenomenon is quite different from that of the Qujialing society because of the significant differences in their social structure and in the way the elites governed.
