《战国策·燕二·客谓燕王》
燕王听说后，同齐国断交，率领天下诸侯的军队进攻齐国，经过一次大战，两次小战，使齐国疲弊，成就了燕王的声名。
燕王闻之，绝交于齐，率天下之兵以伐齐，大战一，小战再，顿齐国，成其名。
When King Yan found out, he broke off relations with Qi and led the armies of the feudal lords of the world to attack Qi. After one great battle and two lesser ones, he exhausted Qi and established his own reputation.
