There may be two sets of stone labels (Jie, 楬) were unearthed from the Cao Wei tomb at Xizhu village in Luoyang, and the funerary objects recorded on them have obvious gender characteristics, belonging to male and female tomb owners. The inscription “Roudou (肉兜)” may be a container shaped like a helmet, slightly deep like a basin. The inscriptions “figure of Buddha” and “Bi-Tian (碧窴) figure of Buddha” are of great significance for the study of early Buddhist statues in northern China. “Bi-Tian (碧窴) figure of Buddha” is currently the earliest record of Buddhist sculptures inlaid with turquoise in China. The records of Parthian ivory in inscriptions confirm the existence of foreign commercial trade during the Wei and Jin Dynasties, and the ivories in the Central Plains during this period have been obtained through the coastal trade route of the Sun Wu.
