When Wang Xiaoyi was three years old, his right hand was curled up due to polio, and the only thing he could hold the penholder with was his left hand. When he grew up, he chose to return to his hometown to take root in the mountain village and teach.
Since 1995, he has taught in 4 remote village primary schools and used "left-hand blackboard writing" to send more than 600 students out of the mountains. In addition to teaching, he also raised funds to build roads, build playgrounds, collect donations of books, and build libraries.
