Zhu Shou was an alias given to him by Emperor Wuzong of the Ming Dynasty, which was his self-proclaimed name outside the palace.
Self-proclaimed Zhu Shou
In the twelfth year of Zhengde (1517), Wu Zong came to Xuanfu and decided to build a Zhenguo mansion here. Wu Zong proclaimed himself the "Governor-General of Military Affairs, the Mighty General and the Commander-in-Chief of the Military Forces", and all official documents were issued in the form of the Mighty General Jun. He also changed his name to Zhu Shou, and later named himself "Zhenguo Gong", and ordered the Ministry of War to archive it. Ministry of payment. Since ancient times, no emperor has ever surrendered his status to the imperial court. He really regards state affairs as child's play.
The "History of the Ming Dynasty: The Anthology of Emperor Wuzong" says that he "enjoyed himself in fun and travels, and got close to the small group, until he signed his official title, and the distinction between the top and the bottom was gone." (Indulging in fun, getting close to villains, and later appointing himself an official, there is no distinction between superiority and inferiority.)
Extended information
Ming Wuzong acted in the name of Zhu Shou
In October of the twelfth year of Zhengde (1517), the Mongolian prince Boyan attacked the pass. Zhu Houzhao was very excited and quickly returned to Beijing to arrange a personal expedition. At that time, it was less than seventy years after the Tumubao Incident, and the courtiers couldn't help but get nervous when they heard the word "personal expedition". So there was another round of persuasion, lessons, and even threats, but Zhu Houzhao was never willing to let go of this opportunity for actual combat, and finally led the troops to fight in the name of "General Zhu Shou."
The two sides fought for several days. Zhu Houzhao went to the front line to fight with the enemy in person. It is said that he even beheaded one of the enemies with his own hands. However, there were many dangers, and "he took advantage of the enemy and was trapped several times." Zhu Houzhao personally directed this battle, killing 16 of the enemy, wounding 563 of his own, and killing 25. This could be considered a victory, because the Tatar army was finally repulsed.
