The excavation of the 2018 Xuewei tomb No. 1 in Reshui cemetery, Dulan County, Qinghai

After a looting case was cracked on March 15, 2018, the Institute of Archaeology of the Chinese Academy of Social Sciences and other organizations promptly conducted a rescue excavation of the looted tomb No. 1 at Xuewei. The tomb is the mausoleum of the king of Touyu-houen under Tubo’s rule in the mid-eighth century CE. It consists of two parts: the tomb compound aboveground and the underground structure. The former includes enclosure walls, sacrificial buildings, a mound, and a cloister. The latter consists of the entry ramp, the tomb pit, the screen wall, the tomb corridor, and the tomb chambers comprised of a main chamber and four side chambers, which is consistent with the document that recorded an “Inner-Mound Shrine of Five Gods.” The main chamber includes mural paintings, red-colored representations of wooden bracket sets, painted double coffins, a coffin platform, and an offering altar. A large number of artifacts predominated by goldware and textiles were uncovered. Amongst them, a silver seal bearing the inscription “seal of the King of Achai, the nephew” provides critical evidence for the confirmation of the status and ethnic identity of the tomb occupant.
