《新唐书·列传·卷七十八》
不久元礼被部下所杀，下属将领也被杀多人，只有秀实因为为人恩义诚信，被士兵们敬服，都在他的周围跪拜，不敢杀害他，将士们另外推举白孝德任节度使。
俄而元礼为麾下所杀，将佐多死，惟秀实以恩信为士卒所服，皆罗拜不敢害，更推白孝德为节度使。
Soon after, Yuan Li was killed by his subordinates, and many of his generals were also killed. Only Xiu Shi was respected by the soldiers because of his kindness, righteousness, and integrity. They all knelt around him and did not dare to kill him. The soldiers elected Bai Xiaode as the new Jiedushi.
