This is a comprehensive study focused on the symbolic significance of traditional costume patterns in the Qiang community of Sichuan. Recognizing culture as the soul of an ethnic group, this study sheds light on how these traditional costume patterns visually represent the Qiang ethnic culture and portray their tenacity and character. Utilizing systematic research into these visually striking patterns, which form a graphical system, this study offers a truthful depiction of the rich cultural heritage of the Qiang people. The paper discloses how a deeper understanding of these traditional costume patterns can enhance the Qiang community’s understanding and appreciation of their indigenous culture and nurture a strong sense of ethnic identity. Engaging with these patterns is not merely an act of cultural preservation but also serves as a potent tool to consolidate unity within the community. By revealing the interplay between traditional costume design and cultural identity, this study contributes to the broader discourse on ethnic studies, cultural preservation, and anthropological design. This research provides an insightful perspective for cultural and social anthropologists, designers, and those interested in ethnic cultures and their visual representations.
