《智囊(选录)·术智部·颜真卿》
安禄山派密探暗中监视颜真卿的举动，见颜真卿只顾喝酒作诗，认为颜真卿不过一介书生而已，不足为虑。不久安禄山果然起兵造反，河东一带完全陷入贼手，唯有平原郡一带因颜真卿早有防范而未陷落。
禄山密侦之，以为书生不足虞，未几禄山反，河朔尽陷，唯平原有备。
An Lushan sent secret agents to spy on Yan Zhenqing’s actions. Seeing that he was only drinking and writing poetry, they believed that he was just a scholar and not worth worrying about. Soon after, An Lushan really did rebel, and the Hedong area had completely fallen into the hands of bandits. Only the Pingyuan area did not fall due to Yan Zhenqing’s early precautions.
