For more than four decades, Zhao Haijin has devoted herself to preserving and revitalizing the traditional Miao embroidery and batik craftsmanship of Hainan Province. Passed down for over 400 years and listed as a provincial intangible cultural heritage item in 2009, the art serves as a "wordless history book" for the Miao ethnic group, preserving their history, traditions and beliefs through intricate patterns rather than written language.

Inspired by nature, Zhao shapes of mountains, rivers, butterflies, flowers and other living forms into vibrant embroidered motifs that carry generations of cultural memory and hopes for the future. She has also embraced innovation by refining double-sided embroidery techniques, developing natural plant-based dyes and blending traditional designs with contemporary aesthetics. Her creations have been showcased at major events, including China International Fashion Week.

Beyond her own work, Zhao is committed to passing on the craft. She offers free training courses, has mentored more than 1,000 embroidery practitioners and regularly takes intangible cultural heritage programs into schools. In Miao villages, girls traditionally begin learning embroidery at around the age of 6, progressing from simple scarves to elaborate headpieces, clothing and batik. With every stitch, they weave nature, history and folklore into fabric, ensuring that this centuries-old cultural legacy continues to thrive in the modern era.
