Sushen is the historical Chinese name for an ancient ethnic group of people who lived in the northeastern part of China and what is in modern times the Russian Maritime Province and some other Siberian provinces. They were active during the Zhou dynasty period. Archeological relics in the area are attributed to the Xituanshan Culture. Chinese Bronze Age archaeologist Zou Heng of Peking University believed that the Sushen were also related to the Lower Xiajiadian culture. The Sushen are thought to have been Tungusic speakers.
