《宋书·列传·卷八十二》
必须等待内部政治稳定军力充足之后，再慢慢地观察敌情，准备好步兵骑兵四十万，使国内不受到困难的侵扰，储藏好二十年的粮食，而远方响应我们的地区也不受到侵扰，然后越过淮河，前指黄河，跨据陇右，出击大漠，那时要到哪里都不是随意呢！
须内教既立，徐料寇形，办骑卒四十万，而国中不扰，取谷支二十岁，而远邑不惊，然后越淮穷河，跨陇出漠，亦何适而不可。
It is necessary to wait until the internal politics are stable and the military strength is sufficient, and then slowly observe the enemy's situation, gather 400,000 infantry and cavalry, so that the country will not be invaded by difficulties, store 20 years of food, and the areas that echo us in the distance will not be invaded, and then cross the Huaihe River, pointing to the Yellow River, and stepping on Longyou, attacking the desert, at that time where to go is not arbitrary!
