Abstract: Historical periodicity is the product of the development of human history. It reflects social and historical phenomena on a regular basis, but it is not an inexorable law of historical development. Breaking out of historical periodicity has been an important theoretical and practical subject for the CPC members in the last century. In the new era, the CPC Central Committee with comrade Xi Jinping as the core has found a creative way to jump out of historical periodicity, i.e., by self-revolution. Due to the inner mechanism of self-revolution, it facilitates the CPC to gain people’s recognition in its value, interests, job performance, institution and fairness. As long as the CPC maintain sober and determined, and stick to strict governance over the Party itself, it can break out of historical periodicity by self-revolution.
