College student Zhang Haoqian brought electricity to 16 families in rural areas of the Inner Mongolia autonomous region by solving some thorny technical problems.

Born in the rural area of Urad Rear Banner, Bayannur, the 22-year-old student from North China Electric Power University understood the difficulty of living in the dark and began trying to bring electricity to herdsmen since he entered college in 2010.

"I first helped them to install a wind power facility to produce electricity and storing it in a battery. However, I underestimated the severe weather, and the battery lost power quickly," Zhang recalled.
