The spirit of innovation is attributed to the fearless character of the Chinese nation, which is not afraid of new challenges and has the courage to accept new things. Adhering to the principles of integrity rather than the old, respecting the past rather than restoring the past "is a precise grasp of the innovative and enterprising spirit of the Chinese nation, and also a profound interpretation of the methodology of cultural construction. To build modern civilization of the Chinese nation, we must adhere to integrity and innovate. Uprightness is the fundamental system of the guiding position of Marxism in the ideological field, the fundamental requirement of "two combinations", the cultural leadership of the CPC and the cultural subjectivity of the Chinese nation. Respecting the past means inheriting the past and enlightening the present. The innovation of Chinese civilization is not the groundless innovation that cuts off history and tradition. It is based on the great practice of the Chinese nation, grasps the profound foundation of Chinese civilization over 5000 years, constructs Chinese theory, explains the Chinese path, and innovates and creates on the basis of respecting tradition. While safeguarding the integrity of the Chinese nation, we constantly strive to move forward; While respecting the excellent traditional Chinese culture, we should not forget to explore and innovate. On the one hand, "keeping the right track" moves forward, on the other hand, "respecting the past" innovates, integrating both sides, and walking side by side. Innovation creates new ideas, new discourse, new mechanisms, and new forms. Under the guidance of Marxism, we must truly make the past serve the present, the foreign serve the Chinese, make dialectical choices, and bring forth new ideas, achieving an organic connection between tradition and modernity. Innovation is an enterprising spirit. From "Although Zhou was an old state in the Book of Songs, Daya" to "Gou Ri Xin, Ri Ri Xin, Ri Ri Xin, and Ri Xin" in "Li Ji Da Da Xue"; From Confucius' "those who know are not confused, those who are benevolent are not worried, and those who are brave are not afraid" to the "Book of Changes" of "poverty leads to change, change leads to success, and continuity leads to long-term development", the excellent traditional Chinese culture contains rich innovative and innovative ideas and vigorous creative vitality. The spirit of innovation and progress that is inherited in one continuous line and does not adhere to fixed laws is deeply embedded in the genes of Chinese people, shaping generations of Chinese people. Self improvement, innovation, and keeping up with the times are the eternal courage and spiritual integrity of Chinese civilization, and are the spiritual codes engraved in the bones of the Chinese nation. It is precisely because of this innovative and self-improvement spirit of "constantly striving for excellence, and taking innovation as the way", as well as the fearless character of "fearless of new challenges and daring to accept new things", that the Chinese civilization, which has lasted for more than 5000 years and has never declined, has emerged. At present, the great changes in the world that have not happened in a hundred years are accelerating the evolution. It is even more necessary for us to continue the Chinese context, grasp the innovation as the endogenous power of Chinese civilization and the spiritual character of the CPC people, respond to historical changes and understand the problems of the times, and constantly inject strong power to comprehensively promote high-quality development. Innovation is a pragmatic action.
