The work aims to propose a development strategy of Shangdang Duijin cultural and creative products based on the symbiosis theory to realize the symmetrical reciprocal symbiotic development of Duijin and its cultural and creative products.Through the investigation and analysis of the development and design status of Duijin process and related cultural and creative products, the symbiotic status of Duijin process and cultural and creative products was evaluated. From the perspective of symbiosis, the symbiotic units of Duijin cultural and creative products and their existing and pending symbiotic interfaces were sorted out, and the development ideas of Shangdang Duijin cultural and creative products were explored. In the development and design of Shangdang Duijin cultural and creative products, there are problems such as insufficient symbiosis, lack of systematic symbiosis interface, and unsatisfactory symbiotic state, and its development potential is far from being realized. In the development of Duijin cultural and creative products, the attention should be attached to increasing symbiotic energy, strengthening symbiotic interfaces, optimizing symbiotic environments, and expanding symbiotic fields to try to develop new ideas and new ways of cultural and creative product development and design.
