《辽史·本纪·卷四》
二月初八，皇上将要南幸，因诸路尚有未平定者，召太子及群臣商议对策，大家都说 ：现下襄、镇、朔三州，尽已平定，然而吐谷浑为安重荣所引诱，仍未归服听命，应当派兵讨伐它，以警告其他各部。 
二月壬辰，上将南幸，以诸路有未平者，召太子及群臣议，皆曰： 今襄、镇、朔三州虽已平，然吐谷浑为安重荣所诱，犹未归命，宜发兵讨之，以警诸部。 
On the 8th of the second month, the Emperor was about to travel south, because there were still some roads that had not been pacified, the Crown Prince and the ministers were summoned to discuss countermeasures, and everyone said: "Now the three prefectures of Xiang, Zhen, and Shu have all been pacified, but Tuyuhun has been lured by An Chongrong and has still not surrendered or obeyed orders, troops should be sent to attack it as a warning to the other tribes."
