Cao Zhiqin, a shadow play puppeteer, manipulates leather puppets during a performance in Zhenhu Township of Xiji County, Guyuan, Northwest China's Ningxia Hui autonomous region, Jan 12, 2015. The Chinese shadow play is performed by manipulating flat leather puppets against a lit-up translucent screen. The art form was registered in the Representative List of the Intangible Cultural Heritage of Humanity by the UNESCO in 2011. Cao Zhiqin, who is 67, started learning shadow puppetry when he was a child. As head of a local puppetry troupe, Cao has worked hard to promote shadow puppetry, hoping that people can still enjoy the fun of this folk art. [Photo/Xinhua]
