Kangxi's suppression of the San Francisco rebellion was fundamentally a victory for the forces of justice. The rebellion launched by Wu Sangui and others is aimed at splitting the separatist regime, which cannot be supported by the people morally, and failure is inevitable. The counter-insurgency in the Qing Dynasty avoided the division of the country, was conducive to the consolidation and development of a multi-ethnic unified country, met the wishes of the people and won the support of the people of all ethnic groups. At the same time, it strengthened centralization of authority's strength and improved its ability to resist foreign enemies. Since then, the Qing court began to solve the frontier problems.
In addition, the anti-Qing camp headed by Wu Sangui is weak, with internal mutual utilization and many contradictions, which can't stand long-term military strikes and political disintegration. And Wu Sangui made a strategic conservative mistake from the beginning, so that he was in a passive position. He was timid in the overall situation of resisting the Qing Dynasty, trying to divide the south of the Yangtze River, which made a military commander taboo and provided time for the Qing court to send troops.
When Emperor Kangxi saw that the Lord was Wu Sangui, he took the countermeasure of resolutely attacking Wu Sangui, never giving him a chance to compromise and make peace, but leaving the door wide open for other traitors, as long as he was willing to surrender and let bygones be bygones, so as to divide the enemy and weaken Wu Sangui's wings, thus isolating Wu Sangui, choosing to divide and conquer, and finally pacifying the rebellion in San Francisco.
