The Derung Highway was opened in Yunnan province in November 2014, linking the country's smallest ethnic group to the outside world. The Dulongjiang township, homeland of 70 percent of the Derung ethnic group in China, sits on the southwestern border of the country. Before the highway was opened, access to the township was blocked by snow from October to late April. [Photo by Zhou Mingjia/Asianewsphoto]
