After the fall of the Ming Dynasty, the Manchu Qing outside Guanwai were able to suddenly sit in a contemptuous place, thus rebelling against the imperial court and stirring up China, which was entirely a problem within the country. Li Chengliang's self-esteem allowed Nurhaci to develop, while the intelligence and sale of stolen goods of the Jinshang clique enabled the Manchu Qing to continue to grow.

Another subtle point is that after the fall of the north, the former peasant rebel army led by Li Dingguo's ministry, which rebelled against the imperial court, gave up opposing the imperial court and united against the Qing. From complete confrontation to putting aside contradictions and uniting to resist the Qing Dynasty, the basis of the unity of the two sides is the great national righteousness, the struggle against "horse racing and staking land", "three massacres" and "shaving hair and changing clothes"!
