Teacher Hua Jungang takes an outdoor English class in his home at the Dongyu village, Qingxu county of Taiyuan, North China's Shanxi province, April 30, 2012. The 39-year-old had both legs amputated due to a previously unknown disease when he was just graduating from college in 1994. The amputee started to hold English training courses in his home as a way of realizing his dream of becoming a teacher in 1997. More than 1,700 students have taken his courses throughout the past 15 years. While Hua's career was on a roll, he was dealt another blow in 2009 when he was diagnosed with kidney failure. Having sold all his property for the high-cost of dialysis twice a week, he still manages to continue his courses. [Photo/CFP]
