Chu Jinxia (L) teaches her daughter Chu Liwen in a studio in Chu Iron Picture factory in Wuhu, East China's Anhui province, Sept. 18, 2014. Chu Jinxia, an inheritor of iron picture craftwork, learned the art from her father Chu Yanqing, a great master of iron picture. Having a history of about 350 years, the iron picture was listed as the first batch of national intangible cultural heritages in 2006. The iron picture craftwork, which uses iron as material to make pictures, has been transfered from generation to generation in Wuhu, East China's Anhui province and now has been introduced to college students and professors, which leads a new road for the craftwork to develop itself.[Photo/Xinhua]
