《明史·列传·卷一百》
不知兵法中各种兵器交互使用，应当以长卫短，短以救长，这是第一；三军的士卒各有擅长之技，战鼓军旗等，都应有所准备，现今都弃置不用，这是第二。
不知兵法五兵迭用，当长以卫短，短以救长，一也。三军之士各专其艺，金鼓旗帜，何所不蓄？今皆置不用，二也。
Not knowing that the various weapons in the art of war should be used interchangeably, that the long should protect the short, and the short should save the long, this is the first reason. The soldiers of the three armies each have their own special skills, and war drums, military flags, etc., should all be prepared, but now they are all abandoned, which is the second reason.
