《资治通鉴·唐纪·唐纪五十六》
李以通过宦官升官为耻辱，及至将领们为他饯行送别，音乐奏起时，李落着眼泪说： 我老了，已经安心在外面的军镇上任职了，宰相可不是我所能胜任的啊！ 
鄘耻由宦官进，及将佐出祖，乐作，鄘泣下曰： 吾老安外镇，宰相非吾任也！ 
Li felt ashamed to have rising through the ranks with the help of eunuchs. When the generals held a farewell banquet for him, Li broke into tears and said: I am old, and I am content to take up my post at the military garrison outside the city. I'm not capable of being a prime minister!
