Kangxi's victory over Wu Sangui was also a fluke. Let's analyze the strength of Wu Sangui. When Li Zicheng and Manchu fought for the world, Wu Sangui, who was guarding Shanhaiguan, was the most important pawn. As a result, he fell to the Qing Dynasty and changed the history for hundreds of years.

Wu Sangui also became the roaring dog of the Qing government. After the Qing army entered the customs, Wu Sangui, as a pioneer of the Qing Dynasty, went all the way south to Yunnan, helping the Qing Dynasty to complete the basic reunification. Few people in history of qing dynasty have achieved such success as Wu Sangui.

The Qing Dynasty even repaid Wu Sangui by dividing up the land and enfeoffment. They also knew that it would be a pipe dream to defeat the country so soon without his help. Wu Sangui has been consolidating his power in Yunnan since he proclaimed himself the King of the Day, leading troops to crusade against bandits and pacify the Shuixi Tusi, thus maintaining the stability of Yunnan for a period of time and maintaining a good order in Yunnan.

But he did not give up the training of soldiers. He knew that he was not really accepted by the Qing government, so he had to be vigilant. After years of painstaking efforts, Wu Sangui's strength is very strong. It is no exaggeration to say that Yunnan people only know Wu Sangui, but not the Qing emperor.

The Manchu Dynasty also wanted to restrict Wu Sangui, so it asked Wu Sangui to lay off employees because of insufficient pay. This is not only to weaken his strength, but also to test Wu Sangui's loyalty. Wu Sangui laid off 36,000 troops without saying anything, but most of them were recruited from all over the country.

Wu Sangui is still capable. When he started fighting, it was just a small place in Yunnan, all the way to the Yangtze River valley. But in the end, it was also a good hand, and it was not played well. Kangxi had a bad hand and won.
