Judy wrote in the early days when her father Zhu Yuanzhang established the Ming Empire that the strategic location of Beiping City and the geographical location of the capital were actually very beneficial to the Ming Empire, but these were rejected by Zhu Yuanzhang. Zhu Yuanzhang chose the comfortable Nanjing and sealed the Beiping area to Judy. In fact, because of Judy's existence, Mongolia and Jurchen have been unable to form an alliance or form an effective aggression.
Therefore, after Judy ascended the throne in Jingnan, the first thing to do is to build the capital in Beiping. First, the emperor defended his country. Secondly, it is obvious that the geographical location of Beiping has a far-reaching influence on the nomadic people beyond the Great Wall. Because the emperor was in Beiping, all the elite troops of the Ming Empire were hoarded in Beiping, so the cavalry of the Ming Empire in past dynasties were very powerful, and many of them were really elite troops.

At the beginning of Judy's plan to move to Beijing, his wife, Queen Xu, passed away. The mausoleum should have been built in Nanjing, but Judy quietly sent a minister and a feng shui gentleman to Beijing to find Ji Jean to build the mausoleum.
Two years later, more than 20 miles north of Changping, Judy issued a decree that this circle was a restricted area in the mausoleum area. This is the Ming Tombs today. With the death of Queen Xu, ministers realized that this was a signal for the emperor to move the capital.
Later, some ministers in Nanjing began to humble themselves and directly opposed the secret of Ming Chengzu's move to the capital. And they have all been downgraded. Later, ministers strongly demanded that the first capital of the Ming Dynasty be located in Beijing. Judy's wish to move to the capital for many years has finally come true. Historians of later generations believe that this decision means that the political center of China began to move northward, and the geopolitics of China has changed since then.
