Btw, I believe these people to be the asian equivalent of the Scythians. A great drought hit the Tarim Basin region and people migrated east and west...Hakkas-Schytians. (...and they're both related to the Xiongnu, Han, Hun, Saka, etc.)

About A.D. 120, the Scythians from central Asia conquered northern India. Their kings ruled as the Kushan dynasty. . .
