The composite narrative of Chinese modernization represents a critique and transcendence of Western modernization narratives. Chinese modernization endogenously constructs a composite narrative structure: at the level of the narrator, it integrates the leadership of the Communist Party of China with the principal role of the people, forming a multi-coordinated narrative community; at the level of the narratee, it advocates for equality and mutual learning among civilizations, cultivating a value symbiont based on the common values of humanity; at the level of the story, it advances the "Five-in-One" overall layout encompassing economic, political, cultural, social, and ecological progress, shaping a social organism with parallel main threads; at the level of discourse, it connects the past, present, and future, integrates local practices with global perspectives, and creates a spatiotemporal continuum of shared history and domain. Rooted in the practice of the great rejuvenation of the Chinese nation, the composite narrative of Chinese modernization embodies the dialectical unity of concrete universality, subject-object integration, and systemic synthesis. It not only breaks the myth that "modernization equals Westernization" and transcends the development logic dominated by capital, but also, through the creation of a new form of human civilization, provides Global South countries with an autonomous, inclusive, and sustainable new paradigm of modernization narrative, demonstrating profound world-historical significance.
