Liu Zesong, inheritor of the Yuping bamboo flute making craft, prepares for carving on a flute in Yuping Dong Autonomous County, southwest China's Guizhou Province, Nov. 29, 2018. As a traditional Chinese bamboo instrument, Yuping bamboo flute is famous for its clear tone and delicate carving. Made from local bamboo, the flute goes through dozens of procedures before finished and merges folk cultures of other ethnic groups. It was listed as one of the National Intangible Cultural Heritages in 2006. (Xinhua/Ma Ning)
