《旧五代史·后晋·列传十二》
这时，杨光远镇守洛阳，兼管孟、怀二州，既贪图范延光的钱财，又逐渐探明朝廷密旨，于是上奏道： 范延光是国家的奸臣，如果不管束牵制他，一定向北逃往胡地，或向南奔往吴国，请令他到西都居住。 
时杨光远居守洛下，兼领孟、怀，既利其财，复渐测朝廷密旨，遂奏云： 延光国之奸臣，若不羁縻，必北出塞，南入吴，请召令西都居止。 
At that time, Yang Guangyuan was defending Luoyang, and at the same time was in charge of the two states of Meng and Huai. He covetted the money of Fan Yanguang, and gradually found out the secret edicts of the court. So he asked: "Fan Yanguang is a traitor to the nation, if we don't control and limit him, he will certainly either escape north to the land of the Hu or run south to the state of Wu, please grant an order for him to live in the western capital."
