《明史·列传·卷二百零九》
当初，征讨安南的建议出自夏言，皇帝既已责罪了黄绾，就动怒道： 安南之事，本来只有一个人偶议，众人都是附随而已。
初，征讨之议发自夏言，帝既责绾，因发怒曰： 安南事，本一人倡，众皆随之。
At the beginning, the suggestion to conquer Annam came from Xia Yan, and now that the emperor had punished Huang Wan, he was furious, saying: "The matter of Annam was originally proposed by one person alone, and everyone else merely joined in."
