《新五代史·列传·杂传第三十九》
安重荣认为晋不能把他怎么样，于是决意反叛，安重荣虽拿契丹作借口，但暗中派人和幽州节度使刘晞相勾结，契丹也认为后晋多事对自己宥利，庆幸安重荣作乱，希望他们两败俱伤，想借机窥伺中原，因此没有对安重荣发怒。
重荣谓晋无如我何，反意乃决。重荣虽以契丹为言，反阴遣人与幽州节度使刘晞相结。契丹亦利晋多事，幸重荣之乱，期两敝之，欲因以窥中国，故不加怒于重荣。
An Chongrong thought that Jin could not do anything to him, so he decided to rebel. An Chongrong used the Khitan as an excuse, but secretly sent someone to collude with Liu Xi, the envoy of the Youzhou Festival. The Khitan also thought that the Jin Dynasty had a lot of things to do and it would be good for them. They were glad that An Chongrong had made trouble and wanted them to suffer both, so they could take the opportunity to spy on the Central Plains, so they did not get angry with An Chongrong.
