及至德宗回到长安的第二年，李抱真入朝对德宗说： 在崤山以东宣布赦文时，士兵们都感动得流下了眼泪，我看到人情这样，便知道平定敌军是不足为虑的了！ 
及上还长安明年，李抱真入朝为上言： 山东宣布赦书，士卒皆感泣，臣见人情如此，知贼不足平也！ 
In the second year of Dezong's return to Chang'an, Li Baozhen entered the court and said to Dezong: When the amnesty was announced east of Mount Yao, the soldiers were moved to tears. Seeing such sentiment, I knew that it would be no cause for concern to quell the enemy.
