Zubu (Chinese: 朮不姑 or 阻卜 or 阻䪁, also referred to as Dada or Tatars) was the common name of Khamag Mongol, Khereid, Naiman and Tatar tribes from the 10th to 12th centuries. Little is known in detail about this group. The name "Zübü" might means “left” in Khitan language,[1] or might be derived from Xiongnu's ruling tribe Xubu.
