Since 2019, China has promoted “changing customs and transforming traditions” as a key strategy for cultural and social reform, aiming to enhance grassroots morality and civilization. Implemented through a “co-creation” governance model, the strategy engages party and government leadership, community mobilization, associations, and public participation, emphasizing collaborative governance. Examples from villages in Hubei illustrate how retired and young party members lead reforms by promoting simpler wedding and funeral customs, while communities establish platforms to facilitate public acceptance of new norms. Associations, such as Red and White Councils, effectively use digital and traditional tools for outreach. Public engagement is strengthened by innovative methods like the points system, stimulating intrinsic motivation for change. Policy mechanisms, including clear village regulations and local cultural integration, reinforce regulatory constraints and community acceptance. Ultimately, by mobilizing multi-entity participation, fostering shared governance, and leveraging traditional culture, this strategy effectively reshapes local customs toward greater social harmony and cultural progress.
