A picture taken by a drone shows the scenery of the mist-shrouded Longtoushan scenic spot in Nanzheng district, Hanzhong city, Shaanxi province. Located at the junction of Sichuan and Shaanxi province, Longtoushan scenic spot is enveloped in misty clouds all year round, with looming mountains and forests looking much like a Chinese landscape painting.[Photo/Xinhua]
