Wang Xingyong installs and maintains rooftop solar panels for clients ranging from villagers to factories, and said his business has doubled every year since 2016.

Wang said he slowly won people over, starting with his family and friends, putting forward the money for the equipment himself, and then moving on to other villages with the results.
