《明史·列传·卷一百三十二》
陛下说宫禁之中严守机密，外廷怎能知晓。枚乘有一句话，说： 想叫别人不知道，不如自己不去做。 没有做了事情别人不知道的。
陛下谓宫禁严密，外廷安知，枚乘有言 欲人弗知，莫若弗为 ，未有为其事而他人不知者。
Your Majesty said that the palace was heavily guarded and that the outer court would not know. There is a saying by Mei Cheng: "If you don't want others to know, then don't do it." There is no action that others will not know about.
