《汉书·传·冯奉世传》
如果这样，怯弱的形势显露出来，羌族就会趁机进攻，各少数民族一齐响应，互相煽动起兵，我恐怕汉朝要征发的兵役就不止四万了，这不是金钱所能解决的。
如此，怯弱之形见，羌人乘利，诸种并和，相扇而起，臣恐中国之役不得止于四万，非财币所能解也。
If so, the sign of cowardice will be revealed, and the Qiang people will take advantage of it to attack. All minorities will respond and incite each other to raise troops. I am afraid that the Han dynasty will have to recruit more than 40,000 troops, which cannot be solved with money.
