Ming Shizhi was disliked by his father's obese emperor Zhu Gaozi

Emperor Akihito, the fourth emperor of the Ming Dynasty and the eldest son of Emperor Mingchengzu Zhu Di, ascended the throne in August of the twenty-second year of Yongle (1424). The following year was the first year of Hong Xi (1425). Zhu Gao was born with a heavy and calm nature, a degree of knowledge in words and deeds, a penchant for reading, and received a formal education in martial arts and Confucian scholarship when he was young. Because of his elegance and benevolence, he was deeply loved by his grandfather Zhu Yuanzhang, but his father really did not like this fat, indie-moving, stumbling walking, and still needing the support of internal servants. Zhu Di favored the education of his three sons, Zhu Gaoxuan and Zhu Gaoxu, his two younger and more martial sons, and let Zhu Gaozi do administrative work with his ministers at the imperial court. From the first year of Jianwen (1399) to the fourth year (1402), Zhu Gaozi gradually became directly involved in local politics, and when necessary, he could not only chew words. When his father led an army against Emperor Jianwen, Zhu Gaozi and his advisers were in charge of the affairs of Zhu Di's fiefdom of Beijing, and defended the rear of Beijing. In November of the first year of Jianwen (1399), he had only 10,000 soldiers under his command, but he skillfully organized the defense of the city and thwarted an attack by Li Jinglong. In May of the second year of Yongle (1404), his father made him crown prince at the request of the university scholars Xie Jin and Huang Huai. From then on, whether he lived in Beijing or Nanjing, he was zhu Gaozi supervising the country when the emperor left. As a result, valuable practical administrative experience has been gained.

During Zhu Gaozi's reign, he was enlightened in politics, developed production, and rested with the people. He pardoned many of his father's former ministers during the Jianwen Dynasty, who were preparing to be executed, and rehabilitated many of the unjust prisons caused by the Battle of Jingnan. Zhu Gaozi spent most of his time reforming the administration, and when appointing officials, Zhu Gaozi paid special attention to Confucian morality and personal morality. Low-ranking officials can also be directly elected to the cabinet as long as they are of good moral character. Similarly, Zhu Gaozi appointed talented and disciplined men to local administrative and judicial positions. He also tried to correct the ills of the judiciary during the Zhu Di period. Reduce unjust imprisonment. In terms of government affairs, Yang Rong, Yang Shiqi, and Yang Pu were appointed to assist the government, and the ancient palace punishment was abolished. Because of financial difficulties, Zheng He stopped going to the West. Taking Tang Taizong as an example everywhere, reducing taxes and resettling displaced people, all this enabled the people of the Hongxi Dynasty to enjoy sufficient recuperation, the productive forces to develop unprecedentedly, and the Ming Dynasty to enter a period of stability and strength, which was also the beginning of what history calls the "rule of Benevolence."

In the first year of Hong Xi (1425), Zhu Gaozi took one of the most drastic measures in reversing his father's policy, moving the capital back to Nanjing, and before the relocation was completed, Zhu Gaozi died in the Forbidden City a month later.
