Fan Wencheng, a great imperial college student, once wrote to Dourgen, "If Qin loses a deer, Chu and Han will chase it away, but I will fight against thieves instead of Ming.". He advocated sending troops to the Central Plains immediately. Therefore, it is necessary to change the previous policy of killing and looting, and "no fighting, no autumn crimes"? .
In other words, if you want to enter the Central Plains, you should not only change the strategy of losing the city strategically, but also win the hearts of the people tactically. Dourgen accepted Fan Wencheng's suggestion and agreed to Wu Sangui's request for fighting. And after being confirmed by Beijing as a peasant army patrol, they "rushed to gather military forces" and competed with the peasant army for the world. ?
Li Zicheng didn't know the seriousness of the situation at this time. On April 13, he led his troops to Shanhaiguan to beg Wu, but he surrendered to him by luck and the marching speed was quite slow. He arrived in Guancheng around 19. At the same time, Wu Sangui has sent messengers to the Qing army for help. /kloc-On 0/5, the emissaries met Dourgen and submitted a letter from Wu Sangui to him, saying that if the Qing army supported them, they would "crack the soil and pay their debts".
It means surrender. Dourgen knew this was a golden opportunity, but he was very cautious. On the one hand, he called his advisers to discuss, on the other hand, he sent people back to Shengjing to transfer soldiers, on the other hand, he deliberately delayed the March and forced Wu Sangui to submit to the Qing Dynasty.
Due to the emergency, Wu Sangui had to agree to Dourgen's request, asking the Qing army to enter the customs as soon as possible, because the Qing army was still ten miles away from the customs on the 21st, the guns in the customs were rumbling and the shouts were loud, and the peasant army had already begun to attack the city. On April 22nd, Li fought with Wu Zaishan Customs.
Dourgen was well aware of Wu Sangui's predicament, so he stood by and watched for a long time. When Li Zicheng was about to capture Luocheng and Beiyicheng, Wu Sangui sent deus ex to him for help several times. It is estimated that the strength of both sides has been greatly damaged, and he sent his troops to enter the customs. In the decisive battle with the peasant army, he put Wu Jun first.
When both sides were exhausted, the Eight Banners attacked again. As a result, the peasant army was defeated and quickly returned to Beijing. It can be said that before and after the famous Kansai War, Dourgen made full use of the class contradictions within the Han nationality and forced Wu Sangui to act as a pawn of the Qing army in the Central Plains.
On April 29th, Li Zicheng acceded to the throne in Wuying Hall. On April 30th, Li Zicheng withdrew from Beijing in the name of offering sacrifices to heaven in the suburbs. On the second day of May, the Qing army entered Beijing.

In ethnic relations, Dourgen first inherited the paternal policy and treated Mongolia well. Horqin, Abagai, Zalute, Erdos, Guoerluos, Tumote, Su Nite, Onniute, Harqin, Aohan and Naihan went to the pass to help the Qing army fight, and Dourgen rewarded them handsomely. Later, the tribute of both sides lasted for a long time.
In addition, leaders of both sides also come and go from time to time, such as Wu Keshan and Ketu, Prince of Li Zhuo of Horqin Department, Zhu Xili, the king of the county, and other dignitaries, and Dourgen personally came to meet the banquet. Dourgen often meets with princes and nobles of various tribes for business, thus deepening their feelings.
In August of the fourth year of Shunzhi (1647), Dourgen personally married Duxigar Zinong, the daughter of Abagai tribe. These are the embodiment of the traditional marriage policy. It was through this means that Dourgen maintained the stability of the north. As Wei Yuan later lamented: "In the early days, our ancestors practiced at a young age, which was the strength of Mongolian consorts.
