Zhu Houzong, Emperor Jiajing, was the second son of Zhu Shiyuan, the King of Xing Xian, not the Crown Prince. In the 14th year of Zheng De (15 19), Xingxian Wang died, and Zhu Houzong, who was only 12 years old, attacked Wang Xing and took over Xingfu. In the sixteenth year of Zheng De (152 1), Ming Wuzong died. Because he had no children, and based on the principle of "brothers as friends", Zhang Taihou, the mother of Wu Zong, negotiated with Yang Tinghe, the cabinet record, and Zhu Houzong, the cousin of Wu Zong, was the heir of the emperor. An heir to a vassal prince who had no royal education entered the political arena of the Ming Dynasty as a "drop-in student" among emperors.
This transfer student is difficult to deal with. Shortly after he ascended the throne, Jiajing, who had just ascended the royal stage, had a quarrel with his ministers. Emperor Jiajing and the veteran minister of Wuzong argued about posthumous title and his biological father for three years. The veteran thought that following the precedent, Jiajing should change his uncle to his father and his father to his uncle. Jiajing refused to accept this practice, and the two sides have been deadlocked. Jiajing wanted to win over some important officials, but they didn't want to and insisted on doing things according to the old rules.
Finally, after three years in Jiajing (1524), after many contests between the two sides, Emperor Jiajing played a little trick and accepted some opponents as court officials, setting an example for them. Jiajing worshipped his biological father, Xian Di Xing, and later named him Xian Di. His biological mother was the Empress Dowager Xingguo, and he was renamed Emperor Xiaozong of Ming Dynasty as "Huang Bokao". Finally, this three-year event ended in the victory of Emperor Jiajing.
After the ceremony, the majesty of Emperor Jiajing was no longer questioned, and the legitimacy of the throne was strengthened. Of course, Emperor Jiajing was not an emperor who only knew how to be clever. In the early days of Jiajing's reign, he created a situation of "reviving Jiajing". Jiajing followed the example of Taizu and Chengzu to implement the "New Deal" and carried out drastic reforms in an effort to get rid of the previous drawbacks.
