Xu Dani (1st L) teaches Nanyin, an ancient Chinese folk music art form originated from southeast China's Fujian Province, for students in Xiamen, southeast China's Fujian Province, Dec. 23, 2014. Nanyin, known as the "living fossil" of ancient Chinese music, literally means music in the south and is a traditional opera in Fujian dialect. Nanyin was spread to Southeast Asia and also introduced to Europe and America by thousands of overseas Chinese, when the Maritime Silk Road flourished during ancient China's Song(960-1279) and Yuan(1271-1368) Dynasties. In 2006, Nanyin was enlisted as a National Non-material Cultural Heritage. Three years later, it was listed as a World Human Verbal and Intangible Cultural Heritage by UNESCO. (Xinhua/Lin Shanchuan)
