《新五代史·列传·晋臣传第十七》
张彦泽两腿打颤不敢抬头看，退下对人说： 我不知道桑维翰是怎样一个人，今天见了，还让人如此恐惧，哪能再见他呢？ 
彦泽股栗不敢仰视，退而谓人曰： 吾不知桑维翰何如人，今日见之，犹使人恐惧如此，其可再见乎？ 
Zhang Yanze's legs trembled and he didn't dare look up, and retreated to tell others: I didn't know who Sang Weihan was, seeing him today, he still makes people afraid, how can I see him again?
