Pupils wave to photographers before getting on school buses in Wubao township, Southwest China's Chongqing municipality, May 29, 2012. The four school buses, whose operational costs are largely being covered by the Jiangbei district government of Chongqing, are making life easier for more than 170 local kids, including pupils and kindergarteners, who used to stumble in the dark on their way to school situated in remote mountainous areas. The price for monthly passes costs 50 or 80 yuan dependent on the length of the journey. [Photo/CFP]
