Craftswoman Tao Yonghong (R) teaches students making hair embroidery in Nanchang, capital of east China's Jiangxi Province, April 13, 2018. The hair embroidery, which has more than 500 years of history, is listed as a provincial intangible cultural heritage. As its name suggests, hair embroidery uses human hair as threads. As Chinese people generally have black hair, it is also called "Moxiu" (black embroidery). (Xinhua/Song Zhenping)
