He brought all the heroes of Liangshan together. When he was in charge of Liangshan, he was in good order, able to balance the conflicts of interests of all heroes, selfless and informal, which was also an important reason why all heroes obeyed him. Bandits rob the whole gang, unite and be friendly, don't seek revenge and fight with each other, don't do things that various gangs don't allow privately, and so on.

And the Ming dynasty! In fact, at the end of the Ming Dynasty, all wars and disasters occurred in the north, while the situation in the south was excellent, and the country was rich and the people were safe. This is also the economic center of the whole country, so as long as the rulers take appropriate measures, this country should be able to resist crises again and again.

This mechanism is hierarchical and the punishment is vicious. This mechanism kidnapped the will of everyone who joined the gang. This is something other heroes don't have. Third, Song Jiang will also use means. Many heroes' families have already contacted Liangshan and been controlled by them. Fourth, Song Jiang is flexible and speaks softly, which is the most irresistible thing for rebellious people in Jianghu.

In the middle of Wanli, Nurhachi rose and his power grew. In the forty-sixth year of Wanli, Nurhachi Fushun captured it. In the forty-seventh year of Wanli, it hit the Ming Army of the Fourth Route and won a great victory in Salhu. In the next few short years, the Ming army lost to Shenyang, Liaoyang, Guangning and other places, until it lost to Shanhaiguan, and there was no strength to fight back on the battlefield.

Therefore, the late Jin advanced, the defense was clear, and the military head became bigger; The literati bureaucratic group reported to the group and refused to cut the meat and offer it. The emperor's family had no overnight food and could only levy Liao Xiang repeatedly. Peasant uprisings all over the country are the inevitable result of Liao conquest.

However, during the period of 1637- 1644, when Li Zicheng became the mainstream of the rebel army, the political system of the Qing Dynasty was mature, and Daming could hardly stop the attack of the Eight Banners Army. Moreover, the previous advantages of military science and technology no longer exist, and the combat effectiveness of the elite of the Ming army in front of the Qing army is very different.

The replacement of the Ming Dynasty by the Manchu Dynasty, even if there were a large number of traitors, was an accidental and extreme result. If Nanming can be unified, I'm afraid there is no hope.
