《资治通鉴·唐纪·唐纪三十七》
安庆绪叩头再拜说： 作为臣下我治军无方，丧失东西二京，并陷于重兵包围之中，没有想到大王看在我父亲太上皇的情份上，远来救危，使我得以复生，恩深如海，终生难以报答。 
庆绪再拜稽首曰： 臣不克荷负，弃失两都，久陷重围，不意大王以太上皇之故，远垂救援，使臣应死复生，摩顶至踵，无以报德。 
An Qingxu kowtowed and said: "As your servant, I am not good at military affairs. I have lost the Eastern and Western Capitals and am heavily surrounded. I didn't expect Your Majesty to risk your life to come and save me in light of my father's status as the former Emperor. You have given me a new life; your kindness is too great for me to repay in my entire life."
