Hong Shude engraves on a preform of a celadon ware in Xiamen, southeast China's Fujian province, April 16, 2015. Hong, a professor at Xiamen Academy of Arts and Design of Fuzhou University, has dedicated himself to celadon since the 1990s. In 2008, he succeeded in firing a kind of celadon which combines modern design elements with the ancient craft of Tingxi Klin, an important representative of celadon in south China during the Song Dynasty (960-1279).[Photo/Xinhua]
