Yongren is a mountainous county mainly of ethnic Yi people. There was a tradition for Yi girls doing embroidery as a hobby in the past. As the market demand for Yi embroidery has grown strongly in recent years, they can do embroidery as a profession to support their families. In 2017, about 280,000 pieces of Yi embroidery were made and the output value of this industry has reached to 33 million yuan (5.2 million U.S. dollars) in Yongren. (Xinhua/Cai Yang)
