The great rejuvenation of the Chinese nation depends on the revival of traditional Chinese culture, and the comprehensive construction of a modern socialist country depends on the comprehensive construction of a cultural power, and the consolidation of the subjectivity of Chinese culture is an inevitable requirement of the development of the times. To grasp and consolidate the subjectivity of Chinese culture in the interweaving of time and space, we must strengthen cultural self-confidence, respond to the history of Chinese cultural development, adhere to cultural consciousness, strengthen the identity of the Chinese national cultural subjectivity, and adhere to cultural self-improvement to create a new glory of socialist culture. With a new starting point and a new journey, in order to consolidate the subjectivity of Chinese culture, we should take Marxism and its Chinese achievements in the era as the soul, and take innovative development and creative transformation of the excellent traditional Chinese culture as the root. Next, We should create a new cultural form with the Chinese path of modernization, and adhere to the "two combinations". Besides, we should take on our missions and work hard, so that we can jointly create a new culture of the times, and jointly build the modern civilization of the Chinese nation.
