五胡乱华
Ancient Chinese texts record that General Ran Min ordered the extermination of the Wu Hu, especially the Jie people, during the Wei–Jie war in the fourth century CE. The Jie were an ethnic group which possessed racial characteristics which included high-bridged noses and bushy beards, and as a result, they were easily identified and killed. In total, 200,000 of them were reportedly massacred.
