《资治通鉴·唐纪·唐纪五十八》
如果朝中的奸臣全部能够驱除，那么，河朔的叛臣贼党就会不讨自平；但如果朝中奸臣仍然存在的话，则虽然讨平叛臣贼党，对于朝廷也没有什么好处。
若朝中奸臣尽去，则河朔逆贼不讨自平；若朝中奸臣尚存，则逆贼纵平无益。
If all the treacherous officials in the court can be expelled, then the rebels and thieves from Heshuo will be defeated without a fight; but if the treacherous officials in the court still exist, then even if the rebels and thieves are defeated, it will not be of any benefit to the court.
