The concept of Confucianism in a broad sense refers to the academic activities of Confucianism and the theory of Confucian classics representing its academic achievements as well as the study and review of Confucian classics and their social activities before the Song Dynasty. It is assumed that “cultural Confucianism” is a concept that indicates a certain special Confucian view and a certain special research method，then “cultural Confucianism”，as a discipline，should contain three branches，namely，Confucian Cultural history，Confucian Culturology and Confucian Philosophy of Culture. Hereby，the author reflects on his own researches of Gu Yanwu. My book，the Chronicle of Gu Yanwu，falls into the category of “Confucian Cultural history”，Study on Gu Yanwu's Philosophical Thoughts and New Benevolence in the Ming and Qing Dynasties：Study on Gu yanwu's Thoughts belong to the category of “Confucian Culturology”. In the sense of “Confucian Culturology”，the ideological essence of the latter two works is to interpret Confucian culture as a moral and ethical culture marked by “benevolence”. On this basis，further research can be made on Gu Xue at the level of “Confucian cultural philosophy”，which means that Confucianism can be understood as a kind of cultural thought that restricts needs of social material life with “virtue”. In the author's opinion，this kind of cultural thought is based on a cyclical world view，which should not be used as the ideological guidance of “Confucian cultural philosophy”，otherwise it will result in the overflow of ultra-conservative cultural thought. The author advocates that “Confucian cultural philosophy” should adopt modern evolution theory as the ideological guidance，and study the “comprehensive innovation” of “returning to the original and opening up new” of Confucian cultural thought，whose essence is to realize the cultural creation of “inheriting the past and opening up the future” through historical activities of “reviewing the old to learn the new”.
