Take it easy dad, coal mining can be tough

A boy wipes dirt off his father's face in a bath at Xinyu Coal Mining Company in Jiexiu city, North China's Shanxi province, June 16, 2011. Mine bosses invited children of their staff members to the company for a get-together with their fathers ahead of Father's Day, in a bid to reinforce a mining safety education campaign among the miners.
