《三国志·魏书·程郭董刘蒋刘传》
现在我们千里远行偷袭敌人，军用物资太多，难以迅速行军，况且敌人得知消息后，一定有所防备；不如将一些军用物资留下，轻装出兵，加倍赶路，趁敌人没有防备而出击。 
今千里袭人，辎重多，难以趣利，且彼闻之，必为备；不如留辎重，轻兵兼道以出，掩其不意。 
Now we are trekking thousands of miles to attack the enemy by surprise. There are too many military supplies, which makes it difficult to march quickly. Moreover, once the enemy learns the news, they will definitely be prepared; It is better to leave some military supplies behind, set out with light packs, travel at double speed, and attack while the enemy is unprepared.
