Although the capital of the Northern Song Dynasty, Kaifeng, was economically favorable, it was extremely unfavorable militarily, which was an important reason for its demise. The defensive focus of the Ming Dynasty was on the north "town of heavy troops, but in the north", and "Jiangnan."

Although the capital of the Northern Song Dynasty, Kaifeng, was economically favorable, it was extremely unfavorable militarily, which was an important reason for its demise. The defensive focus of the Ming Dynasty was on the north, "the town of heavy troops, but in the north", and "the situation in jiangnan could not control the northwest". Therefore, Nanjing is not an ideal place to build a capital. Some people suggested that the capital be built in Kaifeng, but Zhu Yuanzhang, after examination, believed that Kaifeng was the land of four wars and it was not appropriate to build a capital.

In the later period of Hongwu, after recuperation, the social economy of the north was restored and developed to a certain extent, and the idea of moving the capital of the country to the north sprouted in Zhu Yuanzhang's heart. Twenty-four years later, Zhu Yuanzhang ordered the crown prince Zhu Biao to patrol Guanzhong, and the local father and elder welcomed him: "Mountains and rivers are one hundred and two, see the Han Palace WeiYi again!" After Zhu Biao returned to Beijing, he reported to Zhu Yuanzhang on the inspection situation and presented a map of Shaanxi, and Zhu Yuanzhang was very happy and had the intention of migrating to Guanzhong. Unexpectedly, contrary to people's wishes, Zhu Biao returned to Beijing for only a few months, and he could not afford to fall ill, which caused a great mental blow to Zhu Yuanzhang, who was already in his twilight years, and the matter of moving the capital had to be shelved.

In a ritual stove article personally written at the end of this year, Zhu Yuanzhang wrote: "The world has been running for decades, and everything is in place according to the ancient times. The situation in front of and behind Victoria Palace Castle is not symmetrical. I wanted to move the capital, but now that I am old, my energy is tired, and the world is newly determined, I do not want to work for the people. And there are many ups and downs, only to listen to the sky. But may this heart be appreciated and blessed to its children and grandchildren. Zhu Yuanzhang understood that in his lifetime, it was impossible to realize the idea of moving the capital!
