《新五代史·本纪·唐本纪第六》
梁、唐军对峙于河上，李继韬以潞州降梁，庄宗很忧愁，召嗣源商议说： 继韬以上党降梁，而梁正在急攻泽州，我们若出其不意袭击郓州，能够断梁的右臂，可以吗？ 
是时，梁、唐相拒于河上，李继韬以潞州叛降梁，庄宗有忧色，召嗣源帐中，谓曰： 继韬以上党降梁，而梁方急攻泽州，吾出不意袭郓州，以断梁右臂，可乎？ 
The Liang and Tang armies confronted each other on the river. Li Jitao surrendered to Liang with Luzhou. Zhuangzong was very worried and called Sizheng to discuss: "Jitao surrendered to Liang, and Liang was attacking Zezhou. If we unexpectedly attack Yanzhou, would we be able to cut off Liang's right arm?"
