《明史·广西土司传》关于上思州“仍以土官袭”的记载是错误的,并且误导了后来的研究者,以致形成了上思州“改流复土说”。然而,通过对明代典籍的梳理,我们可以发现:上思州虽在改流后历经多次“复土”之争,但从未成功过;《明史稿》编纂者王鸿绪实际上是上思州“改流复土说”的始作俑者,但毛奇龄对张嵿奏言的表述对王鸿绪有所误导,而且这些关键性的奏言并不见诸于明代历史典籍,因此他要为该错误负一定责任。 The records of “History of the Tusi and Guangxi Tusi” on Shangsi “is still erroneous” and misled the later researchers, resulting in the formation of Shangsi Prefecture. However, through the sorting out of the classics of the Ming Dynasty, we can find that although the state of Shangzhou was repeatedly contested by the “returning to the earth” after the reversion, it never succeeded; Wang Hongxu, the complier of the Ming Dynasty’s draft, However, Mao’s account of Zhang’s remarks was somewhat misleading to Wang Hongxu, and these key remarks did not show up in the history books of the Ming Dynasty, Negative errors bear some responsibility.
