Abstract: To encourage those who were afraid of invaders, under the escalating threats, a few patriots living in Shanghai stood firm to spread the faith of winning the war against Japan by furnishing a comparison between China and Japan from economy to the military through Japan During the War. Having learnt the political economics in Japan, Song Fei-ru was devoted to analyzing Japans industry crisis during the war. In the war, Japans industry was highly dependent on the overseas market for importing materials and exporting products. Rather than falling back before the fierce enemy, Pan Angqian contemplated how to resist the Japanese imperialism through writing the book Japan Diplomacy in the War, in which he figured out that the more lands Japan occupied in China, the more troubles Japan faced in the world. Under the escalating threats, Chiang Bai-li, a Kuomintangs high general, gradually spread the idea of resisting Japan by the lasting strategy in his book Japanese: Research by a Foreigner, which analyzes the Japanese character. He points out the internal contradiction in their character, which indicates the end of their eventual demise. These books on Japan during the war played a key role in the Second Sino-Japanese War for they not only maintained the faith of winning the war against Japan, but also encouraged Chinese people to take weapons to fight against Japanese invasion for independence and freedom.
