Gougou (alias), a four-year-old with terminal cancer, strokes the face of his mother on a bed, in Southwest China's Chongqing municipality on June 26, 2014. The boy, from Southwest China's Guizhou province, was brought by his parents to Chongqing in a preparation to donate his body after death. With his illness worsening, Gougou became anxious and fretful, and always kept mother by his side. [Photo/CFP]
