《智囊(选录)·兵智部·李愬》
李愬准备袭击蔡州的时候，先前曾有窝藏间谍要灭族的律令，李愬后来将旧令撤销，一律不予追究。
李愬之将袭蔡也，旧令敢舍谍者族。
When Li Su was preparing to attack Caizhou, there was a previous law stating that anyone who harbored spies would be executed along with their entire family. Li Su later rescinded the old law and decided not to pursue those crimes.
