《旧唐书·列传·卷八十三》
马王忌妒李晟的名声，加上对他礼节不周，命李晟去京城朝拜，唐代宗将李晟留在禁军里，任右神策军都将。
璘忌晟威名，又遇之不以礼，令朝京师，代宗留居宿卫，为右神策都将。
Ma Wang was jealous of Li Sheng's fame, not to mention that he was inattentive towards him, so he ordered Li Sheng to go to the capital to pay a courtesy call. Tang Daizong kept Li Sheng in the capital to serve as the Head of the Right Divine Strategy Army.
