tHEiR BLUE(她们的蓝)is a thesis project dedicated to exploring, promoting, and honouring Miao Batik, one of the Intangible Cultural Heritages (as defined by the United Nations Educational, Scientific, and Cultural Organization in 2003) of China, and its inheritors—the Miao women. The Miao are one of the 55 recognized ethnic minorities in China.

For more than two millennia of Miao Batik's existence, Miao women used beeswax to paint on cloth and dye it using indigo plants, thereby depicting and preserving the cultural and historical journey of the Miao people. Through this art form, they capture their reflections on life and convey hopeful wishes for future generations.

This research project employs a multidisciplinary approach, including research-creation, storytelling, and interviews with inheritors of Miao Batik to explore the protective processes of Chinese traditional culture/intangible cultural heritage and the inadequate protection of women's social rights in Chinese (Miao) society. The project's creative output includes an artist’s book, videos, illustration designs, and Miao Batik artworks. Moreover, due to the unique aspects of Chinese/Miao culture and language expression, this thesis is written in both Chinese and English, with translations of references first processed through translation software and then refined by me.
