If we no longer adhere to the traditional research scope of judging unjust cases or true cases,but instead start from analyzing the historical details to further examine the origin and development of the"Lan Yu Case",we can find that the outbreak of this case was somewhat sudden.It was directly triggered by Lan Yu's southern expedition to Ülüg Temür and resulted from Zhu Yuanzhang's constant coercion and testing of Lan Yu in response to a specific situation.Behind it was a covert game between Zhu Yuanzhang and Lan Yu,in which Zhu Yuanzhang always maintained the absolute initiative,leaving Lan Yu bound to lose.Combined with the analysis of other objective historical materials,it can be seen that the statement in Records of Rebellious Ministers,which claims that Lan Yu allied with Jingchuan Marquis Cao Zhen,Puding Marquis Chen Huan and other peers to rebel,is highly doubtful and unreliable.On the contrary,some young heirs stationed in Shanxi at the time were more likely to be Lan Yu's primary co-conspirators among the nobles.
