Introduction to the three mysterious cases: Zhu Changluo (1581~1620) of Mingguangzong was the eldest son of Mingshenzong. Concubine Zheng, who was favored by Shenzong of the Ming Dynasty, wanted to fight for the crown prince position for her son Zhu Changxun, but she had a conflict with Zhu Changluo. In 1615, there was a "beating case" in which the madman Zhang Cha broke into the crown prince's palace with a wooden stick. In 1620, when Ming Guangzong succeeded to the throne and was named Taichang, he died after eating the red pill given by Li Kezhuo, the minister of Honglu Temple. This is called the "Red Pill Case". Before Zhu Youxiao, the son of Emperor Guangzong of the Ming Dynasty, succeeded to the throne, Li Xuanshi and the eunuch Wei Zhongxian who raised Zhu Youxiao wanted to move into the Qianqing Palace with him. However, they were opposed by the court officials and moved to the Yaluan Palace. This was the "Palace Move Case". The confusion between the three cases reflects the fierce internal struggle within the court in the late Ming Dynasty. After his death, Ming Guangzong was buried in the Qing Tombs of the Thirteen Tombs in Beijing. The academy was also banned. This strange injustice was not resolved until Ming Sizong came to power in 1627 to punish Wei Zhongxian.
