Itwon a gold prize at the Panama Fair a century ago. Xuan paper was first made in Xuanzhou (Anhui Province today) during the Tang Dynasty (618-907). The paper gets its name from Xuancheng where the raw materials for making paper were bought and sold. There are two kinds of Xuan paper—raw Xuan and processed Xuan in different lengths. The first is good for calligraphy and flower and bird paintings and the latter is best for figure drawing.展开更多
