The report of the 20th National Congress of the Communist Party of China pointed out: "As the largest Marxist ruling party in the world, our party must always win the support of the people and consolidate its long-term ruling position, and must always maintain a clear and firm determination to solve the unique problems of the major party." At the second plenary session of the 20th Central Commission for Discipline Inspection, To deeply grasp the unique challenges of the Communist Party of China, it is necessary to understand its inevitability, uniqueness, and systematic approach through historical thinking, dialectical thinking, and systematic thinking, enhance historical initiative and action consciousness, and forever maintain the advanced nature and vitality of the Party on the new path of catching up, so as to make the Party's foundation evergreen. 1. To deeply grasp the inevitability of the unique challenges faced by a major party through historical thinking, any political party's challenges do not arise out of thin air, but are the result of the combined effects of specific historical conditions, historical tasks, and complex characteristics of the times. To deeply grasp the unique challenges of the major party, it is necessary to grasp the historical tasks within the historical laws and deepen the understanding of the inevitability of the unique challenges of the major party through historical thinking. The unique problem of the big party is the result of the interweaving of historical environmental changes and changes in the times. History often advances in leaps and turns. The development of social history often does not follow the established pure general pattern, but has a jumping and tortuous nature. The complexity and variability of social and historical development determine the diversity and complexity of the specific social environment in each historical period. This diversity and complexity always lead to various contradictions and conflicts in the development of social history, forming the main contradiction chain and problem domain of historical development. The specific development of these overall contradictions and problems constitutes the challenges faced by a country or political party. The unique challenges faced by the major party are precisely the ones that arise from the changes and tests of the international and domestic environment in which our party operates. From an international perspective, the world is currently experiencing unprecedented changes and accelerating evolution. A new round of technological revolution and industrial transformation is deepening, and the impact of the century's epidemic is far-reaching. The trend of anti globalization is rising, and unilateralism and protectionism are clearly rising. The world economy is recovering weakly, with frequent local conflicts and turbulence, and global problems intensifying. The world has entered a new period of turbulence and transformation. From a domestic perspective, China's development environment has also undergone profound changes and is currently in a critical period of achieving the great rejuvenation of the Chinese nation. The closer we approach national rejuvenation, the less smooth it will be, and the more risky and challenging it will be. The situation and environment are changing rapidly, the importance of reform, development and stability, the multitude of contradictions, risks, and challenges, and the greater the test of our party's governance and governance is unprecedented. The unique challenge of a major party is the original mission and shoulder of a proletarian political party
