The composition of the enemy is very complicated, among which, besides the Japanese, there are a large number of China people mixed in, and sometimes China people even account for more than 70%. Many enemy leaders also came from China, such as Wang Zhi, Xu Hai and Chen Dong. The two groups should cooperate with each other and cover each other, which makes it easier to be aggressive. Why do China people collude with the enemy?

This has to mention a policy that was implemented at that time in the Ming Dynasty-closing the country to the outside world. On the one hand, the policy of closing the country to the outside world is to resist foreign invaders, but this "blocking" method has also blocked a major economic source for people in coastal areas. For the sake of wealth, many people take risks. Became an accomplice of the Japanese invaders.

Second: combat effectiveness

Compared with the Ming army, the enemy's fighting capacity is extremely strong. As Japan is in the Warring States period, both samurai and ronin have stood the test of war and have rich practical experience. Moreover, Japanese samurai have a high status in Japan and exist as a privileged class separated from production. Since childhood, I only focused on practicing martial arts, so my martial arts is high, far higher than that of Ming soldiers.

The weapons used by the enemy are also beyond the reach of the Ming army. One of the most famous is the Japanese knife, which is extremely sharp. Its quality far exceeds that of Ming dynasty waist Dao, and its length is twice as long. A row of swords and guns of the Ming army are often cut down in battle. Secondly, the enemy's bow is longer than China's, and the arrow is also long and heavy. Although it has a short range, high hit rate and great power, even China people survived.

Tactically, the enemy is good at small group action, flexible, and often scattered, ambushed and circuitous with a few troops, which can actually surround and defeat the superior forces of the Ming army.

On the other hand, the Ming army was completely corrupt, most of them had no fighting capacity and discipline, and faced a lot of defeats by the Japanese army. Officers also have no good restraint. Huang Renyu's "Fifteen Years of Wanli" commented: "No matter how the official documents emphasize that this war is a government officer's encirclement and suppression of pirates, it is actually a layman in China who deals with Japanese professional soldiers."

Third: Ming government corruption.

At that time, the failure of the Ming Dynasty was very dark, and Emperor Jiajing was fatuous and shameless. Yan Song, a traitor, dominated the world, while Zhao Wenhua, a confidant, and other traitors competed for the title. The generals Zhu Wan and Zhang Jing who made meritorious deeds were actually killed. This greatly hindered the promotion of the Ming army.
