《宋史·列传·卷二十四》
有人对皇上说 ：张绅家里很富，不会这样，仅仅因为吕蒙正贫贱时请他救济不如意罢了。 皇上命令马上恢复官职，吕蒙正不予分辩。后来考课院得知张绅的真实情况，又贬张绅为绛州团练副使。吕蒙正第二次任宰相时，太宗对他说 ：张绅果然有赃。 吕蒙正既不分辩也不感谢。
用二事，迁秩盐铁判官，拜集贤院学士、知梓州、应天府，徙荆南，进龙图阁直学士、知广州，陶甓甃城，人以为便。
Someone told the emperor, "Zhang Shen is wealthy at home, he wouldn't do that, it's just because Lü Mengzheng was poor and asked him for help but he refused." The emperor ordered to reinstate Zhang Shen immediately, but Lü Mengzheng said nothing. Later, the Examination Institute found out the truth about Zhang Shen and demoted him to the deputy commander of the Jizhou Group Exercise. When Lü Mengzheng served as prime minister for the second time, Emperor Taizong said to him, "Zhang Shen was really corrupt after all." Lü Mengzheng neither defended himself nor expressed gratitude.
