This study focuses on the functional transition and value regeneration of Chinese button symbols in cultural and creative jewelry. The Chinese button, as a traditional Chinese clothing knotting technique, carries profound cultural connotations. With the acceleration of industrialization, the practical function of the Chinese button has gradually been replaced, but its cultural symbol attribute has been reactivated in the cultural and creative field. Through systematic deconstruction and reconstruction, the Chinese button has transformed from a “collar knot” to a “chest ornament,” completing a value reconstruction from a practical function to a cultural identity expression. The study, through literature review, case analysis, and design practice, verifies the regenerative ability of the Chinese button in modern jewelry design and proposes a “cultural gene – design translation – emotional scene” tripartite transition mechanism. At the same time, the study points out the challenges faced by the Chinese button in terms of sustainability, including the disconnection of craftsmanship and cultural dilution, and puts forward corresponding solutions. In the future, it is necessary to further deepen technological empowerment and cross – cultural dialogue to promote the global value regeneration of traditional craftsmanship.
