During the reign of Kangxi, Wu Sangui and other San Francisco forces were eliminated (1673), Taiwan Province Province was unified (1684), the rebellion of Junggar Khan and galdan was put down (1688-1697), and the Sino-Russian Nebuchadnezzar Treaty was signed. In the Battle of Jacques, Kangxi sent a general from Heilongjiang Province, Sabusu, to successfully expel the Russian invasion of the Kangxi River Basin (more than 3,000 Qing soldiers fought hundreds of Cossacks in Russia far behind in the northeast of China, but they couldn't fight for a long time, and finally forced the czar to agree to peace talks by siege tactics, which shows that the Qing Dynasty was far behind the West in military science and technology), and recovered Jacques (now Skovorodino, Russian Federation) and Nebuchadnezzar. He built a summer resort in Chengde, which was used as a place for the nobles of Mongolia, Tibet and Kazakhstan, but it also created a precedent for the large-scale construction of royal gardens in the Qing Dynasty, which increased people's suffering.
Kangxi had a lot to say when he studied algebra, geometry, astronomy and medicine from missionaries in China. He also likes Christianity very much. Later, Kangxi gradually discovered that the Vatican tried to interfere too much in Qing politics. After the prince converted to Christianity, he used it as a tool to fight for power and profit, so he began to boycott Christianity. However, Kangxi did nothing to promote western learning, which made China's science and technology lag far behind the West. Kangxi practiced martial arts since childhood and was good at riding and shooting. Duolun formed an alliance. He hit a long-range target with a hard bow, which shocked the Mongolian princes present. Kangxi always got a lot of wild animals when hunting in the paddock. I was still doing geometry proof the night before, and I had a good time the next morning, even killing two or three horses, which shows that Kangxi is full of energy. Kangxi once claimed to kill 300 rabbits a day, which shows his confidence in his own force (people today also doubt whether it is possible to kill so many rabbits a day with bows and arrows).
Mongolia was once divided into three parts (Monan Mongolia, Moxi Mongolia and Mobei Mongolia). After two generations' efforts, Nurhachi and Huang Taiji of Monan Mongolia completely surrendered to Monan Mongolia, that is, Inner Mongolia. Moxi Mongolia is Junggar Mongolia. Junggar Galdin led troops south, threatening the central dynasty. Kangxi decided to personally expedition and defeated Galdin. Mobei Mongolia and Kangxi used a series of measures to win over Kangxi to lie, which completely solved the problem of Khalkha Mongolia, that is, outer Mongolia. Therefore, Kangxi said: "In those days, the earthwork construction in Qin was developed, and I was kind to Kerkha to keep the north better than the Great Wall." China From the Huns in Qin and Han Dynasties to the Ming Dynasty, the historical problems of Mongolia have not been solved for two thousand years. Kangxi solved this problem, which is a historic contribution.
Kangxi attached importance to cultural education. He personally presided over the compilation of many important classics, such as Kangxi Dictionary, Pei Yunwen Fu, Wen Qingjian, Panorama of Kangxi and Integration of Ancient and Modern Books. There are more than 60 kinds of classics compiled by Kangxi, about 20 thousand volumes, which are important spiritual wealth in Chinese culture. The Kangxi Dynasty made the Qing Empire stand in the east of the world. At that time, there was Peter the Great in Russia and Louis XIV in France, and Kangxi was great compared with them. Kangxi had the largest population, the richest economy, the most prosperous culture, the most open territory and the strongest national strength. During the reign of Emperor Kangxi, the territory of the Qing Dynasty extended from the sea in the east, to Qingshan in the west, to Zengmu shoal in the south, to Xing 'an Mountains in the north, to Balkhash Lake in the northwest and to Sakhalin Island in the northeast, with a total area of about13 million square kilometers.
