What major mistake did Li Zicheng make to make the three generations of Qing Dynasty dream of entering the Central Plains?

Even after Li Zicheng successfully captured Beijing, he still pursued the policy of suppressing the officials of the former dynasty and did not want to win the hearts of the people, so Li Zicheng lost the support of a large number of bureaucrats. Wu Sangui, especially, who was originally a courtier of Li Zicheng, heard that this policy changed and took refuge in the Manchu government, which laid a solid foundation for Li Zicheng's failure.

First of all, when Li Zicheng's army broke through the Ming Dynasty, Chongzhen was unable to resist Li Zicheng, and finally Chongzhen chose to commit suicide. According to the truth, the king of a country is dead, and Li Zicheng should embark on the peak of his life, unify the Central Plains and make great achievements, but it turns out that everyone's evaluation of Li Zicheng is too high.

Secondly, history has given Li Zicheng such a good opportunity. In the end, Li Zicheng lost to the Qing Dynasty. To put it simply, the Dashun regime in Li Zicheng was soon replaced by the Manchu regime. There is nothing more than a problem with Li Zicheng's leadership, without considering the actual situation.

Then many people speculated that Li Zicheng was carried away by victory after the invasion. Both he and his rebel army lived a life of drunkenness and dreaminess, which gave the Qing dynasty an opportunity. But in fact, Li Zicheng's army is still the same, and training is still training. In any way, there is no problem of depravity.

Finally, the real reason for Li Zicheng's failure is that Li Zicheng didn't realize that there was something wrong with his leadership policy, but continued to suppress the officials and the landlord class in the Ming Dynasty, without thinking about winning the hearts of the people. So Wu Sangui was afraid to surrender to Li Zicheng when he heard the news, and finally chose the Manchu camp.
