601 years ago today, on August 12, 1424 (July 18, 1424 lunar calendar), Emperor Chengzu of Ming Zhu Di died. Emperor Chengzu of Ming Zhu Di (1360 - August 12, 1424), Han nationality, was the third emperor of the Ming Dynasty, reigned from 1402 to 1424, and his era name was Yongle, so later generations called him Yongle Emperor, Yongle Emperor, Yongle Emperor, etc. On April 17 (May 2), the 20th year of Emperor Shun of Yuan (1360), Zhu Di was born in Yingtian Mansion (now Nanjing). In December of the 31st year of Hongwu, in order to guard against the rebellion of Zhu Di, Emperor Jianwen sent Zhang Bing, the attendant of the Ministry of Industry, to be the envoy of Peiping, and both commanded the envoys Xie Gui and Zhang Xin. Then he ordered the governor Song Zhongtubing to station troops in Kaiping, and transferred the army that was originally under the jurisdiction of King Yan in Peiping. Later, he launched the Battle of Jingnan and launched an army to attack Emperor Jianwen. He ascended the throne in Nanjing in 1402 and was changed to Yuan Yongle. During his reign, Zhu Di reformed the organization and set up the cabinet system. He personally invaded Mongolia five times, recaptured Annan (Jiaozhi), established the Nuer Gando Division in the northeast, set up Hami Wei in the northwest, and established provincial administrative divisions in the southwest Guizhou and other regions. This consolidated the north-south border defense and maintained the unity and integrity of China's territory. Zheng He was sent to the West many times to strengthen friendly exchanges between China and foreign countries. At the same time, he also ordered people to compile the "Yongle Ceremony" and dredge the Grand Canal. The capital was moved to Beijing in 1421, which played a very positive role in strengthening the rule of the Ming Dynasty. During his reign, he developed from the devastation after the disaster to the prosperous age of economic prosperity and national strength, known as "Yongle prosperous age" in history. After the death of Zhu Di, his posthumous name was Tianhong Dao Gao Ming Guangyun Shengwu Shengong Chun Ren to Emperor Xiaowen, and his temple name was Taizong, and he was buried in the Changling Tomb of the Ming Dynasty. In September of the seventeenth year of Jiajing (1538), Ming Shizong changed his posthumous name to Qitian Hongdao Gao Ming Zhaoyun Shengwu Shengong Chun Ren to Emperor Xiaowen, and changed his temple name to Chengzu. "Ming Shi ¡¤ Chengzu Benji" says "The strategy of The sixth division came out again and again, and the dust in the Mobei Dynasty was clear. In the year of the season, Wei De Ya was quilted, and he was dressed in the four directions, and almost thirty countries were ordered to pay tribute by the dynasty. The scale of the fall was so wide that it was far away from the Han and Tang Dynasties. Success is strong, and it is prosperous. "
