《旧五代史·后梁·末帝纪下》
天亮时，唐军攻打封丘门，王瓒相迎投降。唐庄宗李存勖入宫，末帝妃子郭氏号哭着迎拜。唐庄宗刚入汴京，听到末帝驾崩，怃然叹息说 ：对方的恩惠对方的仇怨，都不涉及他的后代。
唐帝初入东京，闻帝殂，怃然叹曰： 敌惠敌怨，不在后嗣。
When daylight came, the Tang troops attacked Fengqiu Gate, and Wang Zan came out to greet them and surrender. Tang Zhuangzong Li Cunxu entered the palace, and the last emperor’s concubine, Lady Guo, wept and came out to greet him. Tang Zhuangzong had just entered Bianjing and, on hearing of the last emperor’s death, sighed regretfully and said: His kindness and his vengeance have nothing to do with his descendants.
