The captain of the 628 team answered for you: 1, regardless of the overall situation, just like the Kuomintang in the early days of War of Resistance against Japanese Aggression in the textbook, it ran out to engage in civil strife when it was time to be consistent with the outside world. He is short-sighted and has no political talent. He only relies on encouraging farmers to rebel, but he doesn't know how to govern the country with people, just like ordinary thieves and bandits. From the point of view of the Ming Dynasty and the nation, they were all thieves, and only from the point of view of the rulers of the Qing Dynasty were they heroes. At that time, the Ming Dynasty was concentrating its efforts against the late Jin Dynasty in the northeast, and Li Zicheng took the opportunity to rebel and attack Beijing, forcing Emperor Chongzhen to death. Then it occupied Chen Yuanyuan, which led Wu Sangui to become a traitor in a rage and let Manchu enter the customs. The Li Zicheng Rebellion led to the demise of the Ming Dynasty, and at the same time, the people of the Central Plains, including the Han nationality, were massacred and their culture was severely damaged. Then it was oppressed by the Qing Dynasty for more than 200 years, which indirectly caused China to fall from a world-leading country to a sick man of East Asia bullied by foreign powers.
