General Secretary Xi Jinping pointed out in his speech at the mobilization meeting of party history study and education that "the one hundred years of our party is the one hundred years of the determination to practice the original mission, the one hundred years of laying the foundation of the foundation of the wicker road, and the one hundred years of creating brilliance to open up the future." The Communist Party of China's centennial birthday, revolutionary salvation, exploration of nation-building, reform and prosperity of the country, the land of God has undergone radical changes. The Chinese nation has stood up, the socialist system has been established, the Chinese people have become rich, and China, which has suffered so much in recent times, has become strong. There are many reasons why such great changes have taken place, but an important one is that our party has grasped the simple truth that "iron must be hardened by itself" and has continuously carried out a self-revolution with the blade turned inward.

        The iron must be hardened by itself is the endogenous trait of Marxist parties

　　The Communist Manifesto published by Marx and Engels clearly declares that the Communists want to overthrow the bourgeoisie, let the proletariat seize power, and turn capital into public property belonging to all members of society. In the course of the revolution, it was to make the most radical break with traditional ownership relations, and "it was to make the most radical break with traditional ideas in the course of its own development." And to achieve this mission, communists must transform their subjective world at the same time as they transform the objective world. Only by constantly making the most radical break with various traditional concepts can we make the most radical break with traditional ownership relations. The core of traditional concepts is the concept of private ownership, which has been formed and accumulated over thousands of years in a private society and cannot be broken completely in a short time. This difficulty determines that the Communists must strengthen the construction of the Party, carry out a social revolution and at the same time carry out a self-revolution with the most complete break with all traditional concepts, refine the "iron must be hardened by itself", cultivate and maintain the advanced and pure character of the Communists, and strive unremittingly to achieve the noble historical mission they have been entrusted with. The Party's efforts to achieve its noble historical mission will be unremitting.
