Abstract: In the context of coordinating urban-rural integrated development and comprehensively advancing the rural revitalization strategy,restoring cultural confidence,perpetuating the spirit of public culture,and reconstructing the public cultural space of traditional villages have become urgent priorities for rural cultural revitalization.The granny tea (Apo tea) tradition,a customary practice among elderlywomen in the Shangta region of Qingpu District,Shanghai,embodies the dual characteristics of traditional village culture and intangible cultural heritage.The evolution of its public cultural space is inseparable from national development policies and institutional arrangements,manifesting a transformative logic:from unilateral operation to collaborative cooperation,from female-centered social interaction to diversified and compound social functions,and from single-factor drivers to mutually embedded identification.However,it confronts three major developmental dilemmas:the erosion of public participation,the transformation of traditional life scenarios,and the growing misalignment between cultural supply and demand.Reconstructing public cultural space and revitalizing traditional culture in traditional villages requires not only the state's continued strengthening of public cultural service capacity but also concerted collaboration among participating groups within traditional village public culture.Only by continuously stimulating the endogenous momentum of traditional village public cultural development can we perpetuate the public spiritual value of traditional culture amid the rise of national culture,discover new functions of public cultural space in traditional villages through integrating tradition and modernity,and embrace new forms of virtual public cultural space in traditional villages in the wave of information media.

Key words: traditional villages, cultural, public cultural space, granny tea (Apo tea) tradition, cultural change, cultural community
