《新五代史·列传·杂传第三十二》
王建虽然待刘知俊很好，但也暗中妒忌他的才能，曾对手下人说： 我老了，快死了，刘知俊不是你们所能控制的，不如尽早对付他！ 
建虽待知俊甚厚，然亦阴忌其材，尝谓左右曰： 吾老矣，吾且死，知俊非尔辈所能制，不如早图之！ 
Although Wang Jian treated Liu Zhijun well, he was secretly jealous of his ability, and once said to his subordinates: I am old, and will die soon, you will not be able to control Liu Zhijun, it would be better to deal with him as soon as possible!
