Under the background of the rural revitalization strategy, college students have become an important new force for rural talent revitalization. Taking left-behind children in rural areas of Xi’an and its surrounding areas as samples, this paper focuses on “aesthetic education + psychological care” volunteer services, and systematically sorts out the practical value, key bottlenecks, and optimization paths of college students’ participation in rural civilization practice. The research finds that college students’ short-term teaching support has achieved remarkable results in “inspiring aspirations and supporting intelligence”, but there are problems of “three insufficiencies” (insufficient publicity, insufficient channels, insufficient capabilities) and “two deficiencies” (lack of management and lack of incentives). The paper proposes a dual-track volunteer project model of “Riyu Program (Caring Reading)” and “Technology Dream-Building”, and constructs a long-term mechanism of four-party collaboration among “colleges and universities - government - public welfare organizations - rural schools”, providing a paradigmatic reference for replicable and promotable college students’ assistance in rural revitalization.
