Abstract:Yu Dafu 's recognition of Japanese culture and Japanese national character from the early favor of Japanese culture and sad telling about weak people to rational evaluation of Japanese culture and Japanese national character in 1930s includs a tangle of love and hate feelings. He takes Japan as a reference to China's national culture and national characters, and then makes criticism on them, which is just a miniature of the recognition of Japan of the Chinese who studied in Japan in Meiji Taisho Period.
