Various award certificates are seen in an elementary student's home in Bozhou, East China's Anhui province, Feb 20, 2012. The hilarious certificates recognize bad behavior and qualities, such as being naughty, sloppy, sweet-talking, or cheeky. Some parents have urged education authorities to ban the sale of these certificates near schools due to the possible harm generated to a learning atmosphere, although the certificates are popular among students. [Photo/Asianewsphoto]
