冉闵
In 350 CE, Ran Min restored native Han rule to North China and issued a cull order, starting the Wei-Jie war. As a result, thousands of Wu Hu () were killed, and their uprisings suppressed with the exception of the Xianbei tribe in Northeast China. In 352 CE, the Murong Xianbei attacked Ran Wei with generals and soldiers from both Xianbei and Han backgrounds.
