Introduction: Unable to bear the oppression of the different races in northern China, the Chin Dynasty transferred the capital to the lower reaches of the Yang-tzu River in 317 AD, and thenceforth, the tract along the river came under the rule of the Eastern Chin. At the same time, many different races were in conflict and, at last, in 386 AD, the Northern Wei Dynasty was established and obtained control of northern Chian, thus causing the direct confrontation of North and South.
