Judy was originally a vassal, and his fief was in Beiping, that is to say, Judy's power and foundation were in Beiping. Of course, after he ascended the throne, he still had to live in the palace. He was already the emperor and the world was his. Beiping and South Kyoto are his lands, and they are the same everywhere. But the problem is that the Ming emperor Judy regained the throne from his nephew Wen Jian. He ascended the throne abnormally. When he breached the palace, he didn't catch Emperor Wen Jian. In order to make the courtiers in Nanjing submit to him, he slaughtered many ministers loyal to Wen Jian. In other words, Judy's road to the throne is bloody and very cruel.
When Emperor Chu first ascended the throne, the situation in the world was delicate, and the emperor Wen Jian disappeared. There are many loyal people in Nanjing. These people are either killed, or run away and hide, or they may defect to Judy under the pretence. If these people do something, Judy's hard-won country will be in danger. Therefore, the generals and ministers of Nanjing and Judy are not at ease. Beiping is different. The courtiers and generals in Peiping are all people who follow him to conquer the world. These old ministers from Nanjing came to Beiping as strangers, and if they want to make a difference, they can't escape Judy's eyes. Therefore, for political reasons, Judy will go to Beiping.
Ming emperors' tombs were generally built in the suburbs of the capital, because it was convenient for future emperors to worship their ancestors and protected the Ming tombs from being destroyed under the eyes of the Ming Dynasty. So after Judy moved to Beiping, he chose the cemetery in the suburb of Beiping. Of course, Judy can also choose the cemetery in Nanjing. After all, Zhu Yuanzhang's tomb is in Nanjing, and the tombs are buried with his father, son and grandson. But Judy gave up Nanjing and chose Beiping, which may also be related to superstition. He didn't choose Nanjing as the cemetery, and he didn't want to be too close to Zhu Yuanzhang's cemetery. The ancients were superstitious. They think they will go to another world to live after death. Judy doesn't want to be buried in Nanjing, and probably doesn't want to live too close to Zhu Yuanzhang. After all, he took the throne of Zhu Yuanzhang as the designated heir. If we were buried together after death, Judy would not have a good life, so he chose the cemetery in Beiping.
