《资治通鉴·晋纪·晋纪五》
魏咸熙年间，因为一支部落太强，分为三个部落。晋泰始初年，又增为四部落，这时刘猛从内部叛乱，勾结外族敌人；近年郝散之变，也发端于谷远这个地方。
咸熙之际，以一部太强，分为三率，泰始之初，又增为四；于是刘猛内叛，连结外虏，近者郝散之变，发于穀远。
During the Wei Xianxi period, because one tribe was too strong, it was divided into three tribes. In the early years of the Jin Dynasty, it was increased to four tribes. At this time, Liu Meng rebelled from within and colluded with foreign enemies; in recent years, Hao San's change also started from this place of Gu Yuan.
