“How do you move and click a computer mouse？” “ How do you press the buttons on a cell phone？” I watch a large group of schoolchildren at Jian An Elementary School asking painter Hsieh Kun-shan one question after another. Hsieh loves the attention， telling jokes and making funny noises. “Do you use chalk？” one student asks. “Of course not，” he replies with a wide smile. “I'm not that foolish！” The children burst into laughter. Earlier， Hsieh displayed a slide show of his artwork. But Hsieh isn’t here just to talk about art.
Hsieh has mastered the technique of painting by holding the paintbrush in his mouth. When he was sixteen， Hsieh had a terrible electrical1 accident. Both of his arms and the lower part of his right leg were amputated. He also lost sight in his right eye. But Hsieh didn't dwell on these devastating2 losses. In his autobiography，3 he wrote， “I had no idea what I could achieve， but at least I made a resolution4 to start something.” He decided to pursue5 art， and took the first difficult steps toward changing his life.
