There is a view that Emperor Kangxi was talented and unwise, failed to grasp the historical opportunity and followed the wrong country. The so-called "prosperous time" can only be said to be the afterglow of the sunset. Second, China's backwardness in modern times began with Emperor Kangxi, because he was in an era of great change, but he refused to make great changes. What he achieved in his life was to artificially prolong the declining feudal society, which made China lose the best opportunity to March into capitalism and left a heavy burden and suffering for modern China. Thirdly, from the perspective of Kangxi's time, before and after he ascended the throne, China and the world were at a critical juncture of the alternation of the old and the new. Britain has started the bourgeois revolution, the colonial expansion of European powers has reached China's neighbors, and Russian forces have penetrated into the Heilongjiang River Basin in China. The situation is both a challenge and an opportunity for the Qing Dynasty. If we can take the opportunity to understand the West, speed up the economic and cultural exchanges between China and the West, learn advanced western technologies, carry out social reforms, and take the lead in establishing a capitalist power in China, the doom of modern China can be avoided. Fourthly, judging from the situation in China at that time, the seeds of capitalism had appeared in the middle and late Ming Dynasty, and were gradually growing by Kangxi, which provided certain conditions for the emergence of capitalism and also showed that China had certain economic conditions for social change. Secondly, China's feudal political ideology at that time was also facing unprecedented challenges: on the one hand, the Qing Dynasty entered the Central Plains, making "the difference between Chinese and foreigners" and "the change from foreigners in summer"; on the other hand, China, represented by Gu and Li Zhi, appeared democratic thoughts against feudal autocracy, which coincided with the enlightenment thoughts in Europe, indicating that China already had the ideological foundation for social change. However, at this critical moment, Emperor Kangxi, who is famous for his wisdom and eagerness to learn, seized the opportunity of the development of the times to carry out reforms, or "set things right" to revive the backward feudal society? Judging from his thoughts and actions, he chose the latter.
