《资治通鉴·后唐纪·后唐纪一》
投降过来的人都说大梁没有什么军队，如果陛下留下部分兵力坚守魏州，保卫杨刘，亲自率领精锐部队与郓州会合起来，长驱直入汴梁，城中本来就很空虚，一定会望风自溃。
降者皆言大梁无兵，陛下若留兵守魏，固保杨刘，自以精兵与郓州合势，长驱入汴，彼城中既空虚，必望风自溃。
People who’ve surrendered have told me that Daliang doesn’t have any troops to spare, so if Your Majesty leaves behind a certain number of troops to hold Weizhou and guard Yangliu, and leads the crack troops to rendezvous with Yanzhou, and then presses all the way into Daliang—whose city is in fact very empty—they will be bound to scatter in panic.
