Workers of a local Xuan paper manufacturer walk past rice straw and bark of Blue Sandalwood tree, both raw materials for making Xuan paper, being sunned at a mountain in this aerial photo taken in Jingxian County, east China's Anhui Province, May 12, 2020. Xuan paper is a type of handmade paper known for its smooth surface and its ability to absorb water and moisten ink. It is originally produced in ancient China and used for both Chinese calligraphy and paintings. The traditional process of making Xuan paper, which involves over 100 steps, has been a UNESCO world intangible cultural heritage since 2009 and is still kept alive in Jingxian County to this day.
