First, without traceability, there is no spiritual support and no soul. After the death of Chongzhen, Xú Zhēng (Prince) was successively controlled by Li Zicheng, Wu Sangui and Dourgen. It is impossible to establish a continuation court in the south. This led to the absence of immediate successor in the Ming Dynasty, which led to the subsequent disintegration of the Ming Dynasty. Attention, this problem is very important in feudal times!

Second, go their own way, disobey each other, fight each other and weaken each other. Since Nanming, the problem of recommending successors in Nanjing has become a key move. There were two opinions at that time. Shi Kefa recommended Zhu Changfang. Ma Shiying and Ruan Dacheng recommended Zhu Youyong (Axe King). Later, Zhu Youyong became the emperor of Hong Guang. However, after they acceded to the throne, they were lazy in politics, and Ruan Dacheng and others tried their best to exclude dissidents. The imperial court was distracted and could not concentrate on the approaching Qing army. In addition, Zuo Liangyu, the general of the Ming Dynasty, conquered the Hong Guang regime in the name of "the frontier of the Qing army". In the end, the regime failed in a short time. After the demise of the Hong Guang dynasty, the ghost king regime was established in the southwest and southeast respectively, and the perpetual calendar was established; The name of the Tang regime was longwu. And regimes such as Shao Wu and Wang Lu Jianguo. However, they could not be unified and even had a military conflict. The Nanming court, which was unable to be unified, was always at home and abroad.

Third, strategic mistakes. At the beginning of the Ming Dynasty, the strategy formulated by the Ming court was to "unite thieves" and regarded the peasant army as the enemy of the Ming and Qing Dynasties, while the slogan of "revenge for your father" in the Qing Dynasty paralyzed the Ming court. In this way, the Ming dynasty was eventually annexed by the Qing dynasty under the guidance of the wrong strategy and eventually perished. Only when the Li Yong Dynasty finally united with the peasant army could it last for more than ten years.

Fourth, there is a lack of generalists. Compared with the shame of Jingkang in the Northern Song Dynasty, the situation encountered by Nanming is actually much better. Because the Northern Song Dynasty implemented a high degree of centralization, all local financial power was centralized, resulting in the local government having no money at all once the capital of the Song Dynasty fell. However, in the Northern Song Dynasty, four generals, such as Yue Fei and Han Shizhong, won one military victory after another, saving half of the country for the Song Dynasty. But in the court of Nanming, there were no real generals. Qin Liangyu is old, and he has only a few "white-armed soldiers"; Zuo Liangyu was selfish and died in the civil war. Shi Kefa is a civil servant, loyal, but lacking military talent; It was not until Li Dingguo, who later recruited peasant troops, continued the anti-Qing situation in southwest China and won a great victory. Unfortunately, it is too late, and the eternal dynasty is also consumed by infighting, which is not good for the overall situation.

Compared with the demise of the Northern Song Dynasty, the situation in the Ming Dynasty was much better. At least after 1644 Shen Jia, the Ming dynasty had soldiers, people, generals and money. But it was because of the lack of soul figures, decision-making on key issues, and infighting that we finally lost to our own people. Pathetic! But this tragedy was actually doomed in the last few years of Chongzhen Dynasty. This is related to several initial decisions of Chongzhen Dynasty. First, in the face of the peasant army uprising and the Qing Dynasty's attack in Liaodong, Chongzhen hesitated whether to stay abroad or settle down first. Anne suddenly followed Yang Sichang's advice. Hong Chengchou and Sun Chuanting were sent to resettle Li Zicheng on a large scale. At the same time, prepare for peace talks with the Qing dynasty. Then, he followed Lu Xiangsheng's advice that "peace can only be achieved if you can fight" and mobilized troops to defend Beijing. In the late Ming Dynasty, in order to save the crisis in Liaodong and cover up the truth that Chongzhen wanted to make peace, the Ming Dynasty sent Hong Chengchou to Liaodong to organize the Battle of Songshan. In the end, the peasant army, which had already died, was resurrected and finally the raid was successful. Imagine if we had resolutely settled down and concentrated our forces against the peasant army. And to negotiate peace outside the customs, and finally to deal with the Liaodong front, perhaps the Ming Dynasty can really realize the Chongzhen Dynasty. Secondly, when the form was in jeopardy and it was impossible to pacify the north, Chongzhen hesitated to move south and stick to it. Imagine if he really went south, leaving the north to fight the peasant army of the Qing Dynasty. At least we can save half the country.

But everything is just a hypothesis, and history has no assumptions. The ending is tragic, and the reason for the ending is worth pondering.

I typed this word for word, I hope you can adopt it.
