In pics: forest rangers in NW China's Gansu

Ranger Feng Dejun (R) and Zhang Detuan patrol in the Qilian Mountains in Jinchang County, northwest China's Gansu Province, Jan. 15, 2020. Located deep in the Qilian Mountains in Jinchang County, there is a natural resource protection station with nine rangers, who patrol over 20 times every month with the longest round-trip distance up to 50 kilometers. And in the winter, a critical period for forest fire prevention, they often have to patrol on foot as it is too dangerous to ride motorcycles on some parts of snow-covered mountain roads.
