Abstract: The "Four Greats" (the great struggle, great project, great cause and great dream) stressed by General Secretary Xi Jinping in his "7.26 speech" is a complex systematic project. First of all, the Chinese dream of the great rejuvenation of the Chinese nation is the goal. Secondly, the great cause of socialism with Chinese characteristics is the banner. Thirdly, the great project of further strengthening Party building with a series of new initiatives is the cornerstone. Finally, the great struggle of facing up to diverse challenges, bravely dealing with all kinds of contradictions, and boldly solving various problems is the spirit. The "Four Greats" is not only the substantive innovation of the Party's theory at this stage, but also an important extension of the Party's theoretical innovation. Individually, they have unique connotation, and together they constitute a logically rigorous organic whole, and based on this, they represent the great practices with the most striking characteristics of the times in contemporary China.
