After the war of Jingnan, in the first year of Yongle (1403), Li Zhigang, an official of the Ministry of Rites, said that Yanjing Beiping was the emperor's "land of dragon's prosperity" and should follow Ming Taizu's example and take Fengyang as its capital. Therefore, Ming Taizu Chengzu vigorously promoted the position of Beiping House in Yanjing, taking Beiping as Beijing and changing Beiping House into Shuntianfu, which is called "in the line".
In the fourth year of Yongle (1406), Ming Taizu wrote a book to build the Forbidden City and the city wall in Beijing on the basis of the Nanjing Forbidden City.
In the 18th year of Yongle (1420), Beijing Palace and Beijing City were built. Beijing Palace, based on Nanjing Palace, is slightly larger. The newly-built Beijing City, with a circumference of 45 miles, is a regular square, which conforms to the ideal capital shape of Zhou Li and Gong Ji.
Ming Chengzu officially moved the capital by imperial decree, and changed Yingtianfu in Jinling to Nanjing and Shuntianfu in Beijing to be the capital. However, there are still six central institutions in Nanjing, which are called Nanjing Ministry and Nanjing is the capital.
