Abstract: For more than half a century,Kang Youwei was the most advanced Chinese who constantly drew wisdom from the west and pursued cultural innovation,system construction and political reform. At the same time,he also represented a group of literati and officials who tried to change the destiny of China to learn new knowledge from the west. Kang Youwei's Deology of New Text Confucianism is not so much a transplanting of western natural science and social science as a modern model of the development of Chinese traditional Confucianism under the influence of western science. Dong-chuan science had an important influence on the formation of the modern literature and classics system that Kang Youwei showed.
