《旧唐书·列传·卷十五》
太宗认为长孙无忌既是帮助他登上帝位的头号功臣，又是自己的舅兄，给他的待遇特别高，经常让他出入自己的卧室。
太宗以无忌佐命元勋，地兼外戚，礼遇尤重，常令出入卧内。
Taizong believed that Changsun Wuji was not only the greatest contributor in helping him ascend the throne, but also his maternal cousin. He treated him with particular respect, allowing him to enter and exit his bedchamber as he wished.
