This study examines the cross-regional dissemination pathways of the hulusi (a traditional Chinese wind instrument) within the educational systems of Lianghe County, Yunnan Province, and cities in Guangdong Province. It explores how this intangible cultural heritage transitions from “source-based culture” to “educational resource,” thereby achieving the collaborative construction of local identity and national cultural consensus. Through a combination of literature analysis and field research, this study systematically presents Lianghe County's rural practice mechanism for building cultural confidence based on the “intangible cultural heritage + tourism + education” pathway, alongside Guangdong's institutionalized teaching and dissemination transformation of cross-regional Hulusi under the policy guidance of “incorporating intangible cultural heritage into classrooms.” By comparing the similarities and differences between the two regions in terms of hulusi resource integration mechanisms, educational adaptation pathways, and cultural identity formation, the author argues that the cross-regional dissemination of intangible cultural heritage is not merely a spatial migration but a complex process involving social reproduction and institutional coordination. The study concludes that establishing a “local-remote” collaborative mechanism that balances cultural consciousness and dissemination adaptability is a key pathway for promoting the sustainable development of intangible cultural heritage.
