《新五代史·列传·杂传第二十七》
王处直见唐庄宗一定要讨伐张文礼，更生疑心，于是暗中和王郁交结，让王郁到北方招契丹入塞以便牵制晋兵，而且答应召王郁为继承人，王都知道后不高兴。
处直见庄宗必讨文礼，益自疑，乃阴与郁交通，使郁北招契丹入塞以牵晋兵，且许召郁为嗣，都闻之不说。
Wang Chuzhi saw that Tang Zhuangzong wanted to attack Zhang Wenli, and became even more suspicious, so he secretly colluded with Wang Yu, and asked Wang Yu to go to the north to invite Khitan to enter the pass in order to contain the Jin army, and promised to call Wang Yu as the heir, Wang knew all this afterwards and was not happy.
