Photo taken on July 15, 2016 shows the Huashan Mountain by the Zuojiang River in Ningming County, south China's Guangxi Zhuang Autonomous Region. Guangxi's Zuojiang Huashan rock-art cultural landscape was added Friday to the World Heritage List at the 40th session of World Heritage Committee held in Istanbul. The rock paintings which consist of more than 1,900 drawings depicting drums and related elements are symbolic records directly associated with the bronze drum culture of the Luoyue people once widespread in the region over 2,000 years ago.
