Photo taken on April 13, 2018 shows details of a piece of hair embroidery in Nanchang, capital of east China's Jiangxi Province. 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)
