The capital of the Ming Dynasty adhered to the concept of "the son of heaven protects the country". Is this concept scientific?

Everything has two sides, and the advantages and disadvantages of the Ming emperor's strategy of protecting the country cannot be evaluated scientifically.

Throughout the history of China, the Ming Dynasty was the most progressive dynasty, and the capital was the frontier base for foreign enemies to attack. Constantly suppressed the remnants of the Northern Yuan Dynasty and made many northern expeditions to safeguard national security and unity. Such a capital location has a great advantage, that is, it can better monitor the front-line wars, allocate resources in time, and always maintain the initiative in the war.

Economically, the capital of the Ming Dynasty played a role in promoting the economic balance between the north and the south, which was followed by the phenomenon that the south was rich and the north was poor. Through the circulation of resources, the country's development has been further strengthened, and cultural exchanges between North and South have become more frequent and smooth.

The biggest disadvantage of Tian Zi's guarding the country is that when the enemy breaks through the border defense line, the capital is almost directly exposed to the enemy. The dynasty that made this mistake was Song Dynasty. The capital was too close to the border, so it was surrounded by others carelessly. Only when the country is strong can soldiers be inspired to fight bravely. When the country is weak, it lacks sufficient strategic depth. Nanming can persist for 40 years. If the capital was successfully moved at that time, it would not be impossible for the Ming Dynasty to be divided into half of the country, at least not much worse than the Southern Song Dynasty, but the kings should all be dead. The Ming emperors were not short of blood and backbone, but they were really out of place for a country.

The Ming dynasty was not particularly calm in the southeast coast, which was also the result of the political center moving northward. The chaos of coastal defense is not only due to the invasion of foreign enemies, but also to the crazy participation of local strongmen and families in smuggling, and even the existence of half-man and half-bandit, which can not be dealt with in time and effectively contained. It is also a serious blow to the tax revenue of the Ming Dynasty, especially in the case of financial collapse in the later period, and the pressure can only be shared equally by farmers, if we understand the farmers in the later period of the Ming Dynasty.
