Subutun

Subutun or Sufutun () is the largest known Shang dynasty archaeological site outside Anyang, located in Qingzhou City (formerly Yidu County), 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.
Archaeological evidence allows conclusion that the site is directly related to the Shang capital Yin (Yinxu), situated to the west. It is a colony rather than the local culture development.
