The vitality of theory lies in innovation. If any theory does not keep up with the development of the times and practice, it will lose its vitality. Continuously advancing theoretical innovation in accordance with the needs of the times and practical development is not only the fine tradition of our party, but also an important magic weapon for the party to lead the people to keep up with the development of the times. The Communist Party of China is not only a promoter of the Sinicization of Marxism, but also a promoter of theoretical innovation. Establishing the results of theoretical innovation as the party's guiding ideology, continuous exploration, pioneering and innovation, and aggressiveness are the inevitable choice for our party to remain invincible. Continuously promoting theoretical innovation is the source of the Marxist party's eternal vitality, the inexhaustible driving force for the development of Marxist theory, and the actual need to promote the development of the cause of socialism with Chinese characteristics.
