Abstract: The thought of national character reformation was the basis of Zhanguo Ce School thought during the period of Anti-Japanese war.Zhanguo Ce School argued that national character made by history and culture since Qin and Han Dynasties was the root cause of China’s decline and inability in coping with the national crisis.As the School leader, Lin Tong-ji mainly criticized the “scholar-official” personality in Chinese national character, attacked the “four poison” and the recurrent disadvantage of “embezzle” in the schoolar-officials’bureaucratic tradition that caused the nationals formed a bureaucratic personality and an appearance of “bureaucratic businessman”, and blamed the traditional concept of loyalty and filial piety that led nationals to think a lot of private morality instead of social morality.All of those national characters were the concentrated reflections of nationals’bad qualities.Those bad qualities were unable to adapt to the requirements for “war” and “force” in temporal “New Warring States Era”.Therefore, he advocated to reform the backward nationalities, recalled the “official-scholar spirit” of the Warring States Era, and built a kind of life view like a “warrior”, and those reformations would enhance the national vitality, achieved the victory of the Anti-Japanese War, and reconstructed Chinese national culture.
