Popular science knowledge has reflexively constituted a knowledge dimension of modern society. At present, there is a significant opportunity to promote the innovative development of science popularization in the new era, making it an opportune moment to construct a system and paradigm for the dissemination of local popular science knowledge. Following Clifford Geertz’s concept of knowledge—characterized by particularity, diversity, locality, and context-sensitivity as opposed to universal knowledge—this paper focuses on “local popular science knowledge,” a vital component embedded within the broader universal concept of “science,” to explore innovative pathways for its dissemination. The communication of local popular science knowledge exhibits characteristics of a nationwide science popularization fervor and fragmented communication patterns. Accordingly, this study proposes strategies such as advancing knowledge inclusion closer to reality, adopting grassroots narratives in two-step communication.
