Xu Liangfan, 37, escorts students on a cliff path as they make their way to Banpo Primary School in Shengji county, Bijie city in Guizhou province March 12, 2013. Xu, who started working at the school last year, is the headmaster of the school and teaches mathematics and gym class. Located halfway up a mountain, the school has 68 students of which about 20 live in the nearby Gengguan village. Students from Gengguan have to edge their way along the narrow cliff path to go to class everyday, alongside Xu who would escort them. The path, which was carved from cliffs over 40 years ago, is the only route between Gengguan village and the school, according to local media.
