Kangxi insisted on withdrawing the vassal, and Wu Sangui was forced to rise up and rebel, but confronted the Qing Dynasty for eight years and finally failed. After all, with the strength of a vassal, compared with the Qing army, it is definitely not able to support a protracted war. Wu Sangui fought until the end, and it was already a failure. He still refused to bow his head and insisted on being the emperor in Hengzhou. However, the emperor did not reach the scale of being proclaimed emperor, and Wu Sangui also knew that the throne was not recognized by history and the world, so he died shortly after being proclaimed emperor.
In the early days of the San Francisco Rebellion, Kangxi adopted the strategy of directly confronting Wu Sangui and first lowering Geng. Geng's title was cancelled, but Geng was advised to surrender to the Qing Dynasty and keep his distance from Wu Sangui. But ... Geng refused to accept Kangxi's persuasion and insisted on rebellion, but unfortunately, because there were contradictions between San Francisco and did not cooperate with each other to resist the Qing Dynasty, he went his own way, so Geng was unable to resist the Qing Dynasty's attack.
Geng finally surrendered after defeating Yu Daqing. However, due to Geng's first surrender, he didn't get a chance when he surrendered again, but was ordered to be executed by Kangxi.
Shang Kexi, another captaincy, was the first to surrender to the Qing Dynasty in the San Francisco Rebellion. That is to say, because Shang Kexi insisted on not rebelling, it did not cause the situation that San Francisco joined forces to fight against the Qing Dynasty, which alleviated many difficulties for the Qing Dynasty to pacify San Francisco. But unfortunately, I was finally dragged down by my son Shang Zhixin. Shang Zhixin refused to surrender, but rebelled, forcing Shang Kexi to threaten his son with suicide. Although he was rescued by the left and right, he ended up in a bleak dusk because of his son's rebellion, and finally ended up in depression.
