In 415, the northern regions of Northern Wei suffered a major famine, causing Emperor Mingyuan to consider moving the capital southward to Yecheng (鄴城, in modern Handan, Hebei), but at the advice of Cui Hao and the official Zhou Dan (周澹), who believed that such a move would quickly expose the actual numerical inferiority of the Xianbei to the Han, he kept the capital at Pingcheng, but also pursuant to Cui and Zhou's suggestion, moved a number of impoverished Xianbei to the modern Hebei region.
