A bronze plate excavated from Xianrentai Burial M4 in Changqing, Shandong Province, exhibits distinct regional characteristics in terms of its shape and decorative details. The surface observation and X-CT analysis revealed a relatively more intricate casting process. The plate body was cast separately from both the plate legs and ears, and casting-on and welding techniques were employed for their joining. Compared to other bronze plates of the same period, the casting process of the Xianrentai bronze plate features a remarkable uniqueness reflecting the exceptional craftsmanship of its creator. This discovery and comprehension have also corrected the group preference in the related archaeological discussions of “seeing humans through materials”, thereby facilitating the realization of academic pursuits of “seeing humans through materials” from both “collective” and “individual” perspectives.
