《新唐书·列传·卷八十二》
后来李抱真回朝进见，向皇帝说： 陛下在奉天、山南时，赦免的命令传到华山以东，听到赦令的士兵都感动流泪，精神振奋，这时我就知道了叛贼不难平定。 
后李抱真入朝，为帝言： 陛下在奉天、山南时，赦令至山东，士卒闻者皆感泣思奋。臣是时知贼不足平。 
Later, Li Baozhen returned to the court to meet the emperor and said: When Your Majesty was in Fengtian and Shannan, the pardon was passed on to the east of Mount Hua, and the soldiers who heard the amnesty order were so moved that they shed tears and were in high spirits. At this time, I knew that the rebels would be easy to suppress.
