《新唐书·列传·卷四十三》
李渤又在上朝时说 ：前些时神策军在幔城夺取京兆府的进食牙盘，没有及时处置，以致宦人更加蛮横。 
渤又诵言： 前神策军在幔城，篡京兆进食牙盘，不时治，致宦人益横。 
At the court meeting, Li Bo said again: "Some time ago, the Divine Strategy Army seized the food trays of the Jingzhao Prefecture in Mancheng and did not punish them in time. As a result, the eunuchs have become even more arrogant."
