405 years ago today, on September 30, 1620 (September 5, 1620, the Ming Dynasty moved the palace. From July to September 1 in the 48th year of Wanli of the Ming Dynasty (1620), the two emperors Wanli and Taichang died one after another. The accession of the new emperor was related to the destiny of the country and became the focus of attention of the government and the public. Emperor Tianqi Zhu Youxiao was neglected since his father, Emperor Taichang Zhu Changluo, was not favored by Emperor Wanli. He did not leave a will until Emperor Wanli died and named him the emperor's great-grandson. Although Zhu Youxiao's biological mother, Wang Cairen, was above Li Xuanshi, because Li Xuanshi was favored, she was insulted and died. Before her death, her last words: "I have a grudge against Xi Li (Li Xuanshi), and I can't express my hatred." Therefore, Donglin believed that Zhu Youxiao had been "insulted and abused" by Li Xuanshi since he was a child. He cried all day long, forming a weak character that was afraid of Li Xuanshi. However, after Chongzhen ascended the throne, he said that Li Xuanshi treated their brothers very well ("Notes of Three Huan"). After Emperor Taichang ascended the throne, Zhu Youxiao and Li Xuanshi moved to Qianqing Palace together. A month later, Emperor Taichang died, and Li Xuanshi took control of the Qianqing Palace. With the support of eunuch Li Jinzhong (Wei Zhongxian) and others, he attempted to force the title of the Empress Dowager. This move aroused the suspicion of courtiers, who believed that he would govern politics from behind the curtain. On the day of Emperor Taichang's death, Yang Lian, Liu Yiqian and other courtiers rushed to the Qianqing Palace and asked to visit Emperor Taichang in tears. They asked to see the emperor's eldest son Zhu Youxiao to discuss his accession to the throne, but they were blocked by Li Xuanshi. Under the efforts of the ministers, Li Xuanshi Fang Zhun Zhu Youxiao met with the ministers. When Yang Lian, Liu Yiqian and others saw Zhu Youxiao, they bowed their heads and shouted long live. They protected Zhu Youxiao from Qianqing Palace and went to Wenhua Hall to accept prayers from ministers. They decided to hold the Ascension Ceremony on the 6th of this month. For Zhu Youxiao's safety, various ministers temporarily arranged for him to live in the Prince's Palace, with eunuch Wang An responsible for his protection. Li Xuanshi's purpose of holding Zhu Youxiao hostage failed, and he proposed that all ministers 'memorial should be submitted to her first for review and then to Zhu Youxiao. The courtiers strongly opposed it. The courtiers asked Li Xuanshi to move out of the Qianqing Palace and move to the Luoluan Palace, but Li Xuanshi refused. Li Xuanshi also requested to first grant himself the title of Empress Dowager and then order Zhu Youxiao to ascend the throne, but was also rejected by the ministers, and the conflict intensified day by day. The date of Zhu Youxiao's ascent to the Qianqing Palace is approaching. By the fifth day of the lunar new day (September 30, 1620), Li Xuanshi had not yet had any intention of moving the palace, and it was rumored that he would continue to postpone his move out of the Qianqing Palace. Cabinet ministers stood outside the gate of the Qianqing Palace and forced Li Xuanshi to move out. Zhu Youxiao's Eastern Palace companion eunuch Wang An was in the Qianqing Palace. Li Xuan was helpless and hugged the eighth princess he gave birth to, hurriedly left the Qianqing Palace and moved to the Luuan Palace in Renshou Palace. On September 6, Zhu You was appointed to Fengtian Gate, which was the emperor's throne, and the next year was changed to the first year of Tianqi. At this point, Li Xuanshi's attempt to become the Empress Dowager and control the government finally turned into a shadow. Although Li Xuanshi has "moved to the palace", the struggle has not ended. After several days of "moving the palace", a fire broke out in the Luuan Palace. After hard rescue, Li Xuanshi and his daughter were rescued. At that time, some people criticized Donglin for going too far: "Who cares for the Emperor's Eighth Sister when she enters the well? Don't complain about it when the deceased goes to the well," accusing them of violating the principle of filial piety and fraternity. Zhu Youxiao, with the support of Yang Lian and others, refuted these statements, pointing out that "I order the suspension of the election of the servant titles to comfort the spirit of the Virgin Mary in heaven. The selection of servants and the emperor's eighth sister were generously supported to comply with the emperor's wishes. Your ministers can respect my heart." Later, he was granted the title of Consort Kang and resettled. At this point, the "transfer of the palace" controversy was temporarily over. It and the Wanli Dynasty case and the Hongwan case of the Taichang Dynasty have always been the subject of party strife in the Tianqi Dynasty. History has been called the three major suspicious cases in the late Ming Dynasty.
