《汉书·传·赵充国辛庆忌传》
如果这样，敌人兵力渐增，要诛杀他们就要用几倍的力量，臣恐怕国家的忧患和负担要用十年来计算，不是两三年就可以了的。
如是，虏兵寝多，诛之用力数倍，臣恐国家忧累繇十年数，不二三岁而已。
If that is the case, the enemy's forces will gradually increase. It will take several times our force to kill them. The minister fears that the country's worries and burdens will take ten years to calculate, not just two or three years.
