The academic circles have discussed "the legitimacy of Chinese philosophy" for many times since the subject of Chinese philosophy was established. For western scholars, the reason why they deny the Chinese philosophy is that they measure and reject the Chinese philosophy by following the mode of western philosophy theory. For some Chinese scholars, such as Fu Sinian, puts forward the view of "Chinese no philosophy" in the view of protecting Chinese Philosophy. The author thinks that no matter China philosophy or western philosophy, they are both philosophy of the same "Genus" under the same "kind". The Chinese and western philosophy have something in common, but they also have their unique implications. When facing the problem of Chinese philosophy legitimacy, the development of Chinese philosophy should be based on the breaking away from western philosophy theory and the development of unique Chinese philosophy implications Besides, we should pay attention to the commonness between Chinese and western philosophy in cross cultural comparative perspective.
