西晋末年的永嘉乱离为国史上一个巨大的变局。从这时起,黄河流域及其附近地区就分崩离析,先后建立了十六个政权。各并立的政权之间,又复时起干戈,生民辗转流离,难得稍有定居之时。这样混乱的局面竟延续了一百三十余年。 Yongjia in the late Western Jin Dynasty was a huge change in the history of the country. Since then, the Yellow River Basin and its vicinity have been disintegrated and sixteen regimes have been established. Between the two parties that are in full force, regains their time and again, and the living people are removed from their homes, leaving little room for settlement. This chaotic situation actually lasted for more than one hundred and thirty years.
