Abstract: In the 1911 Revolution, the Qing government, Yuan, and Sun made a compromise, on which relevant researches have been carried out. This article is based on previous researches on this problem and makes a new interpretation, which is not a new point of view with new evidence, but an effort to grasp the whole evolution of China's political inner logic after the Wuchang Revolution, in order to reach a more accurate understanding of this period of history. In the complex social contexts, their compromise is very necessary, which nothing can hold. Their compromise not only is based on the actual situation and subjective conditions, but is also actively contributed by the internal and external factors.
