From the analysis of the situation at that time, if the * * * of the Dashun regime can be far-sighted and have a clear understanding of the national situation, they can take correct countermeasures. First of all, Li Zicheng must abandon the policy of chasing officials, gentry and landlords to help them pay their salaries, and replace it with frivolous taxes and rectification of official management. As far as finance is concerned, before Li Zicheng 1643, it was historically necessary to implement three-year tax exemption to safeguard the interests of poor farmers, confiscate the property of the Ming Dynasty vassal kings, and help officials and gentry recover their salaries to meet the needs of increasing military and political funds. After the occupation of Beijing, he received the internal funds of Ming Chengzu, confiscated all the property of imperial clan, national qi, famous ministers and eunuchs closely related to the dynasty, which could solve the funds of the army and the political power, even if it was necessary to levy some taxes on officials, gentry and people, the amount was quite limited. As long as this measure is taken, it will be enough to win the support of the vast majority of Han officials and gentry and form a front to jointly deal with Manchu nobles.
However, Dashun Army headed by Li Zicheng did not make necessary policy adjustments according to the changes in the situation. They still pretend to be the defenders of farmers' interests, and continue to pursue the policy of pursuing officials, gentry and landlords within their jurisdiction, pushing them back to a hostile position. When Li Zicheng discovered that this move had caused a bad influence in politics, he ordered it to stop, and the detained bureaucrats were released regardless of whether the stolen goods were finished or not, but the memorial activities in various places continued until the Dashun army was defeated and retreated to the west.
In terms of military deployment, it also highlights the lack of strategic vision of Li Zicheng and other large shunjun troops. According to the truth, when Li Zicheng made a large-scale crusade in Xi 'an with the goal of overthrowing the Ming Dynasty, he should have a well-thought-out plan for the next step against the Qing army. Actually, it's just the opposite. Little did he realize that the Qing army would be his main rival for the world. First of all, the troops he assembled in Beijing were not enough to resist the large-scale invasion of the Qing army. A large number of main forces are distributed in the northwest, Huguang Xiangyang and other four houses, Henan and other places; After the invasion of Shanxi, Kyrgyzstan and Shandong, the troops were further dispersed. Although this kind of deployment has a positive effect on stabilizing the situation of Dashun regime, the result of dividing the troops will inevitably lead to the shortage of troops in the capital and JD.COM.
He neither sent the main force of Dashun Army to Shanhaiguan for protection, nor transferred Wu Sangui, the department with the most experience and strength in fighting against the Qing army, to Beijing, which fully showed that Li Zicheng had no understanding of the grim situation that the Qing army was about to participate in the battle of the Central Plains. Even without the mutiny of Wu Sangui, the 8,000 soldiers and horses of the Tang Dynasty alone could never resist the invasion of the Qing army. Besides, after Li Zicheng enters Beijing, if Wu Sangui is properly appeased, and senior generals of Dashun Army are immediately sent to lead the main force to cooperate with Wu Jun in guarding Shanhaiguan area, the possibility of Wu Sangui's defection is very small, and the situation in JD.COM will be relatively stable.
