First of all, put down the chaos in San Francisco. In the early Qing Dynasty, the emperor shunzhi conferred titles to Wu Sangui, Shangkexi, Guangdong and Geng, Fujian, who supported troops for a long time and forged weapons without authorization, and spent a lot of national military expenditure every year to raise troops, forming a trend of "too big to fail". /kloc-in the spring of 0/673 (the 12th year of Kangxi), Emperor Kangxi wrote a letter to withdraw the vassal, so Wu Sangui rose up against the Qing Dynasty and killed Zhu Guozhi, the governor of Yunnan Province, claiming that all the people in the world had recruited their troops and put forward the idea of "prospering the Ming Dynasty and seizing the people", aiming at the imperial court. In order to maintain national unity, Emperor Kangxi mobilized all military forces to crusade against Wu Sangui. After many years, he finally put down the San Francisco rebellion.
Second, recover Taiwan Province province. In A.D. 1662 (the first year of Kangxi), after eight months of siege and bloody fighting, the national hero finally recovered the whole island of Taiwan Province Province occupied for 38 years from the Dutch invaders, and all the Penghu Islands were under Zheng's jurisdiction. Zheng's long-term separatist regime harassed the mainland, which seriously affected the security of southeast provinces. In the 22nd year of Kangxi (1683), Kangxi took Shi Lang as the prefect of Fujian Navy, sent troops to attack Taiwan, defeated Taiwan Navy and recovered Taiwan Province.
Third, put down the Junggar rebellion. Junggar tribe in northwest China has been burning and plundering the resources and population of other Mongolian tribes for a long time in an attempt to unify the whole Mongolia and restore the glory of Temujin period. Emperor Kangxi assembled military forces from all over the country to guard against blockades, transferred troops to the north to meet them, and successively attacked Wulanbutong and Junggar in Zhao Mo.
In the thirty-sixth year of Kangxi (1698), in February, in view of galdan's refusal to surrender, Kangxi once again wrote a letter to personally expedition. Gordan committed suicide by taking poison in the case of betraying others. At this point, the war to quell the rebellion in galdan during the reign of Kangxi came to an end, and the Gurkha region was reunified with the Qing Dynasty.
