Wu Sangui did play a large role in the Qing Dynasty's struggle to advance into Guannei. Guanning Iron Horse was like a sharp knife to cut thorns for the Qing Dynasty, and in the struggle to pacify Yunnan, Wu Sangui played a great role, and even pushed the power to the Burmese region. The pressure of the other party on Wu Sangui handed over the Ming Emperor to his hands, which was a great achievement.
After worrying about the Qing Dynasty's pacification of Yungui and the capture of the Ming Dynasty's imperial family, the Qing Dynasty did not hesitate to reward the general, and completely handed over the personnel and financial power of the Land of Yungui to him. Wu Sangui became a veritable Emperor of Tu. Why did it know that Wu Sangui would become bigger and stronger, and the Qing Dynasty still risked letting him uphold great power?
The Reason the Qing Court did this was to appease people's minds. The Qing Dynasty's rapid control of the situation in the Ming Dynasty, in addition to the success of the military offensive, was also due to the assistance of the Han Dynasty's military generals. The unification of the Qing Dynasty was not the work of the Eight Banner Army alone, and the Eight Banner Army alone could not govern the world. The generals who pacified the force could attract more Han talents to serve the Qing Dynasty, and even if the other side did not mention anything, the Qing Dynasty would try to give them benefits, mainly to let the people of the world see how they won the hearts and minds of the people.
At that time, the Qing Dynasty actually had no time to take care of the Yunnan-Guizhou region. With the gradual expansion of the occupied areas, the Eight Banners Army was still insufficient in terms of strength, and they could only garrison a limited number of troops in the most important strategic areas. In this way, the southwest region had to first let people like Wu Sangui surrender garrison. Although there were hidden dangers, he was also a courtier of the Qing Emperor.
Letting Wu Sangui guard Yunnan and other places on the spot was also a way to dispose of Wu Sangui and his subordinates. After the unification of Jiangshan, the Qing Dynasty needed less troops, and how to deal with military groups like Wu Sangui was a problem. Once mishandled, the consequences are unimaginable, and the results of the mutiny are even more terrible. Sealing Wu Sangui as the king of Yunnan and letting him solve the problem of the placement of his soldiers on the spot was the best way.
