This book, in less than 100,000 Chinese characters, clarifies the three most complicated and influencing cases in the Ming Dynasty: the Palace Assault case, the Red Pills case, and the Palace Removal case. The author gives thorough analyses to Emperor’s authority and Prime Minister’s rights, the Court and the Eunuchs in the Ming Dynasty, as well as the whole stories of the three cases, and therefore provides readers with a clear and vivid picture of the palace, the court and the society. The book also narrates the revocation of the case decisions during the reigns of later Ming emperors, which reveals the conflicts among different groups of interests that eventually led to the fall of the Ming Dynasty.
