元颢
Within less than two months of Yuan Hao's entry into Luoyang, the Northern Wei loyalist counterattack succeeded despite fierce resistance from Chen's army, and Yuan Hao fled from the city. Chen led his troops on an orderly retreat, pursued by Erzhu Rong. But his army was caught in a flash flood at the Mount Song River (outside Luoyang), and almost completely destroyed - most of the troops either died or deserted. Chen himself escaped back to the south after shaving his head and disguising himself as a monk.
