This study takes the Qiang embroidery, an intangible cultural heritage of the Qiang nationality, as the starting point to explore the innovative application of project-based teaching in art courses in colleges and universities. Through methods such as literature research, case analysis, a three-level project system based on the educational concept of project-based teaching was constructed, and the teaching model reform integrating "four classrooms" was implemented. The study found that project-based teaching significantly improved students' ability to control the design process, market awareness and technical proficiency. Under the school-enterprise cooperation model, the conversion rate of students' works and the satisfaction of enterprises have both increased. The study provides an educational path for the living inheritance of intangible cultural heritage, and at the same time has reference significance for the teaching innovation of traditional crafts in other countries.
