"Paying it forward" is a worthwhile and fulfilling notion that we could use a lot more of in society. Sun Qiang is a visually impaired music producer, currently working in Chicago, the U.S. He arranges guitar music, records, edits and mixes soundtracks for film companies. In his spare time, he and about 40 musicians that are visually disabled voluntarily share audio instructions for others who cannot see, yet want to learn how to use a full-featured music software. Sun's incentive came from his first music mentor Lu Jinshan who didn't turn him down because he was sightless but opened up a magical world of music for him.
