With such a short article about such a complicated process is very difficult, but essential to the Ming dynasty of military errors are written clearly. The demise of the Ming Dynasty military mistakes is the direct cause.'s Internal affairs is the indirect cause of the failure.
　　China is a big country to find the emperor to build a strong army and a military commander was not difficult, but not as good as today's advanced communication and transportation, to ensure an army loyal to himself, not to fight the battle difficult. Spring and Autumn to the Tang Dynasty, the military generals are the professionals, agricultural society was never completely conquered the barbaric society, but civil wars, the suffering of the people I am afraid that by the many. The military is "tail", the emperor to worry unwieldy. Later, the royal family, lessons learned, at least not to royalty to ensure that the generals in power outside. If there is war, the border line of the army only to have the strength, the local military can not have too much power, otherwise, the local military rebellion, and on the imperial power, the better than alien conquest loss.
　　The Northern Contrast this approach is not bad, of course, military commanders in northern nomadic ability, but poor weapons, the general can deal with, but once the term barbarian leader of a civilized society can not be won, it will soon hit their own internal battle , was destroyed inside. Thousands every year, the northern nomads are countless number of internal killing, only a weak dry years than the Central Plains the brutal pain of the Holocaust is much greater national. Otherwise, why the Central Plains after the conquest of northern nomadic people, all scrambling to accept the Chinese civilization?
