On the other hand, since the failure of the Second Revolution, Sun Yat-sen and his allies were trying to rebuild the revolutionary movement. In July 1914 Sun established the Chinese Revolutionary Party (). He felt that his failures at building a consistent revolutionary movement stemmed from the lack of cohesiveness among its members. To that end, Sun required that party members to be totally loyal to Sun and follow a series of rather harsh rules. Some of his earlier associates, including Huang Xing, balked at the idea of such authoritarian organization and refused to join Sun. However, they agreed that the republic must not revert to imperial rule.

Chinese fury against Japan was predictable, but anger was also directed against Chiang and the Nanking government, which at the time was more preoccupied with anti-Communist extermination campaigns than with resisting the Japanese invaders.
