Li Zicheng cut off the dragon vein of the Ming Dynasty, and Chongzhen sent people to cut off Li Zicheng's dragon vein. Why did both sides suffer?
The two parties were busy destroying each other's Feng Shui treasures, and did not notice that Nurhachi was eyeing him outside the pass. Of course, both sides would suffer. In the eyes of modern people, dragon veins are a superstitious term. But the ancients were very persistent about this, especially the ruling class. Having the dragon vein means that you are the emperor's choice, and destroying the dragon vein means destroying the chance of becoming emperor. But can dragon veins really keep the dynasty safe? Li Zicheng and Emperor Chongzhen fought with each other over the dragon veins, and in the end they lost the world.
Is the mutual severing of dragon veins the reason for the failure of Li Zicheng and Emperor Chongzhen? Of course not. Li Zicheng raised his banner to revolt, and Emperor Chongzhen relied on nothing but dragon veins to protect his country's ancestral heritage. Aren't most of the reasons for their failure due to themselves? Although Li Zicheng led the troops in the uprising, he was cruel and unkind, disregarded the lives of the people, and would not appease people's hearts. Not being a wise leader, Wu Sangui surrendered to the enemy, but the people did not support him, and in the end he suffered infamy. The failure of Emperor Chongzhen stemmed from the decline of the Ming Dynasty. Emperor Chongzhen wanted to change, but he had no choice but to face internal and external troubles. How could he change this fate? Once Dragon Vein talks about it, it cannot save the Ming Dynasty at all.
Both sides suffered losses, allowing the Qing army to gain a fisherman's advantage. Li Zicheng and Emperor Chongzhen fought internally in the Central Plains, even destroying each other's dragon veins, while Nurhaci was eyeing the Central Plains in the pass. This is the worst possible situation. Emperor Chongzhen did not expect that before he could win against Li Zicheng, the Qing army would lead his troops into the pass, forcing him to commit suicide. Li Zicheng did not expect that Wu Sangui would surrender to foreign enemies and attract the Qing army to enter the pass. The country he should have gained would be given to Nurhachi. Could this be caused by dragon veins? No, the most fundamental reason is that neither of them is a match for the Qing army. There is civil strife in the Central Plains and they cannot care about foreign enemies at all.
To sum up, the theory of dragon veins cannot change the fate of Li Zicheng and Emperor Chongzhen. It's ridiculous that they don't think about how to defeat the enemy at the moment of the battle, but also think about the survival of the dragon vein. In other words, these two people don't know what the main contradiction is at all, and in the end they can only lose.
