Six Tang dynasty tombs containing bricks with molded figures on them were excavated in the Foyemiaowan at Dunhuang in 1955. Among them, a knight-like figure wearing a bat-shaped hat and a robe from M123 and other funeral items exhibit obvious temporal features. By referring to historical records, relevant funerals, and relics, this paper attempts to date some of the tombs: M123 was probably made in the Kaiyuan era,M125, M134, M141 should be from no later than the beginning of the Jianzhong era, and M 121 was likely made in the period ruled by Emperor Xuan of the Tang dynasty or later.
