《新五代史·列传·唐臣传第十三》
唐庄宗派宦官韦令图监督他的军队，韦令图说： 王建及得到士兵的拥护，怕他有二心，不能让他掌管牙兵。 
庄宗遣宦官韦令图监其军，令图言： 建及得士心，惧有异志，不可令典牙兵。 
Tang Zhuangzong sent the eunuch Wei Lingtu to oversee his army. Wei Lingtu said: Wang Jianji has the support of the soldiers. I'm afraid he has two minds, so he can't be allowed to command the tooth soldiers.
