Shang and Zhou regularly devoured/human sacrificed caucasoid Indo Europeans they captured in wars against the Xirong barbarians in Gansu. The only caucasoid skull found in Shang dynasty sites was a human sacrifice victim. DNA tests of 3000 year old remains of Shang and Zhou nobles at Hengbei showed they were all Mongoloids with Han specific haplogroups of O3 and Q1a1.
