《资治通鉴·唐纪·唐纪三十三》
河北地区都在安禄山的统辖之内，所以叛军经过的州县望风瓦解，郡守与县令有的大开城门迎接敌人，有的弃城逃命，有的被叛军俘虏杀害，没有人敢于抵抗。
河北皆禄山统内，所过州县，望风瓦解。守令或开门出迎，或弃城窜匿，或为所擒戮，无敢拒之者。
The Hebei area is under the jurisdiction of An Lushan, so the prefectures and counties passed by the rebels collapsed in the face of the wind, and the prefect and county magistrate opened the city gates to welcome the enemy, abandoned the city and fled for their lives, or were captured and killed by the rebels. No one dared to resist.
