《后汉书·列传·卓鲁魏刘列传》
今就以盛春之月，兴发军役，扰乱天下，与夷狄相持，这不是垂恩中国，改元正时，由内及外的举措。
今乃以盛春之月，兴发军役，扰动天下，以事戎夷，诚非所以垂恩中国，改元正时，由内及外也。
Now to take advantage of the springtime to raise an army and disturb the world, and to confront the barbarians, is not to show favour to China, to change the era, and to act from within and without.
