Shao Jun gives a class to pupils at Dongshan Primary School in Sanbing Township of Chaohu City, east China's Anhui Province, Sept. 8, 2009. Shao, 42 years old, lost his right arm during an accident at the age of 19. He started teaching at Dongshan Primary School in 1998 and spent 11 years there. As high-grade pupils were gradually transferred to downtown schools, there is one class in the school with only eight pupils. [Xinhua]
