An aerial photo taken on July 17, 2016 shows the Shuangmu (Shuanghe to Muliyuan) Road in Xintang Township of Enshi City, central China's Hubei Province. The 20-kilometer-long Shuangmu Road has a 4.4-kilometer Chegenpo segment, which is built on the cliff of Chegenpo and looks like hanging on a wall from afar. Drones have been in common use in photojournalism in 2016. (Photo:Xinhua/Yang Shunpi)
