A one-man education army in mountains

Song Changcheng leaves his home at 7 in the morning to go to Shanshupo and Fujiazhai villages in Sinan county, Guizhou province, to "collect" his nine "kids" aged between 3 and 5 because he believes they should be accompanied by an adult while walking through the mountains to school.

Carrying the youngest, Jiao Shaoting, on his back, Song leads the other eight children on a path meandering through the mountains in the morning mist. After school, Song takes them back home before sunset.

With their parents working as migrant workers in cities, most of the children live with their grandparents. And they call Song grandpa.
