A resident from Shuangmidi village crosses the Nujiang River via a zip-line in Liuku county of Nujiang Lisu autonomous prefecture, Southwest China's Yunnan province, Feb 2, 2013. More than 98 percent of Nujiang Lisu autonomous prefecture is occupied by mountains and valleys. The zip-lines have been quite popular transportation method along the Nujiang River since the ancient time.
