Sufutun (Chinese: 蘇埠屯) is the largest known Shang dynasty archaeological site outside Anyang, located in Qingzhou municipality, Shandong. Occasional finds by Yidu farmers were reported in 1931; in 1965−66 a chariot burial and four tombs have been excavated, followed by six more tombs in 1986. Though the tombs were robbed, and site itself damaged by road construction, it still yielded a large amount of important finds. Some of the artifacts bear an emblem of Ya Chou, possibly a clan name.
