Liangshan is the largest Yi ethnic group settlement area in China and the area that preserves the most traditional Yi culture. Compared with the "Four Famous Embroideries" of China, namely, Suzhou Embroidery, Guangdong Embroidery, Hunan Embroidery and Sichuan Embroidery, Yi Embroidery has strong colors and rough techniques, reflecting the totem worship and folk customs of the Yi people. It is a form of inheritance of Yi culture in the long history. With its diverse cultural and ecological landscape, it is unique among the embroidery arts of various ethnic groups. The fabrics of Yi embroidery are generally made of kapok and linen plain woven fabrics, as well as other blended plain woven fabrics. The embroidery threads are made of cotton thread, bulked yarn colored thread, mercerized embroidery thread and gold thread. The Yi embroidery technique imitates nature, and the techniques include embroidery, applique, coiling, threading, lock, patching and padding. The patterns are mainly sun patterns, floral patterns, flint patterns, sheep horn patterns and animal tooth patterns, and the colors are mainly green, red, yellow, black and white. Yi embroidery is mostly used on headscarves, flower hats, collars, shoulder pads, lapels, cuffs, belts, capes, and skirt edges of Yi costumes. It also appears on satchels, triangle bags, sewing kits, sachets and other daily necessities. At present, Yi embroidery has become one of the key industries for the development of Liangshan's ethnic culture. By the end of 2020, Liangshan had built a cultural industrial park and 10 industrial bases, and the annual output value of the Yi embroidery industry reached 139 million yuan, helping about 200,000 women in need to achieve flexible employment at home.
