参考译文
Five Nomadic Tribes and Sixteen States
"Five nomadic tribes and sixteen states", namely the "sixteen states" (304 A.D. – 439 A.D.), is a period in Chinese history between the Eastern Jin dynasty and the Northern and Southern Dynasties, when a large number of foreign invasions and separatism swarmed into. Thus this period also was called "invasion of China by five nomadic tribes". They had established many states, and based on sixteen states from them, Cui Hong, a historian of the Northern Wei dynasty, wrote the Spring and Autumn of Sixteen States (the five period of Liang, four of Yan, Three of Qin, two of Zhao and the Cheng and Xia dynasty), thus historians called this period as "five nomadic tribes and sixteen states". The territory of the "sixteen states" covers the northern part of China, Sichuan province, the eastern part of Liaoning province (as far as the northern part of desert), Yangtze and Huai rivers, the western areas and so on.
