In December 2019,a joint excavation by the Xi'an Institute of Cultural Heritage Protection and Archaeology and the Sichuan University School of Archaeology and Museology uncovered a number of Han and Tang dynasty tombs in Shangtapo village,in the southem suburbs of Xi'an.Among them,two early Tang dynasty cave tombs(M14 and M42)were well-preserved,yielding a significant collection of pottery,bronze,iron,gold,and silver artifacts,as well as epitaphs.The epitaphs reveal that the occupant of tomb M42 was WEI Yuanfang,and the occupant of tomb M14 was his son WEI Chengqing.Both father and son died in Baling and were reburied in their ancestral graveyard in Yongzhou in the third year of Shangyuan(676 CE).The tombs of WEI Yuanfang and his son provide valuable information for the study of early Tang dynasty reburial practices and the genealogy of the Wei family.
