2004年3月,陜西省考古研究院和西北大學考古學系在西安市長安區郭杜街道西北大學長安校區建設用地發掘了唐總章二年(669年)司宰寺丞劉智與夫人尹氏合葬墓。該墓形制完整,紀年明確,出土有組玉佩、金銅裝班劍等珍貴文物,為研究唐代輿服制度提供了重要的資料。

In March 2004, the Shaanxi Provincial Institute of Archaeology and the Department of Archaeology at Chang’an campus of Northwest University jointly excavated a joint-burial of Liu Zhi—who was the chief offi cial of Sizaisi and died in 669 CE(Second year of Zongzhang) during the Tang period—and his wife, Lady Yin, during the constructional project of the Chang’an campus in Chang’an district, Xi’an city. This is a signifi cant discovery because the tomb is not only intact but also yields self-evidently datable objects as well as remains that are rarely found such as jade pendants and a ceremonial sword with gold and bronze decorations. In summary, the new discovery provides new information for the research on the ritual court clothing system of the Tang Dynasty.
