In today's rapidly advancing globalisation, the protection and inheritance of regional culture is particularly important. Art design, as an important form of cultural expression, is responsible for transmitting and reviving regional culture. Han embroidery in the Jingchu region is one of the intangible cultural heritages in China, which is a display of skills and a carrier of emotions and philosophies of Jingchu culture. With this in mind, this study explores the specific case of Jingchu Han embroidery and analyses how regional culture expresses and transmits emotions in art design. By analysing the historical background of Han embroidery, its technical characteristics, and its application in modern art design, this paper reveals how regional cultural elements can achieve emotional penetration and stylistic influence in art design. The study also focuses on how the emotional aspects of Jingchu Han embroidery can be borrowed and innovated in modern design practice to enhance artworks' cultural depth and emotional resonance. Jing Chu is one of the important birthplaces of China's history and culture, with a rich cultural heritage and unique regional characteristics. Han embroidery is an important part of Jingchu culture. It is not only a kind of traditional handicraft but also a medium for the people in the Jingchu area to express their emotions and transmit their culture. In modern art design, elements of Han embroidery are widely used, showing its unique artistic charm and cultural value. However, academic and practical circles are still exploring how to express better and convey regional culture's emotions in art design.
