The May Fourth Movement was a series of events where China's youth took center stage. To commemorate its 100th year, CGTN's Go-Getters series is featuring young people trying to make a difference around the country. Today, our reporter Tao Yuan brings us the story of a young music therapist in Southwest China, who is changing the lives of children with mental health issues.

The children at this art studio all live with developmental disabilities. Self-expression might not be their strong suit. But when they sing, they show pure joy. Wu Yulin has been a music therapist for a decade now.

WU YULIN, CO-FOUNDER YUELING MUSIC THERAPY SERVICE CENTER "I clearly remember a boy with autism. The world was like a one-way street to him. There was no opposite direction. One time, we did a New Year's session and we sang about our wishes for the new year. The boy was extremely nervous and kept rocking back and forth. We kept encouraging him. Then, all of a sudden, he said, 'Colored pencils! I want colored pencils.' I was so touched. He had never said anything about what he wanted. Right then and there, through music, he could express himself."

Wu Yulin encourages these children to sing to each other about what they like and who their friends are. And when handed a piece of musical instrument, they never hesitate to create their own rhythm.

WU YULIN, CO-FOUNDER YUELING MUSIC THERAPY SERVICE CENTER "I believe what music offers is some kind of spiritual support and encouragement. It gives life more dignity."

Not just for those with mental health issues. Wu Yulin's team also visits community centers to encourage young kids to open up through music.

WU YULIN, CO-FOUNDER YUELING MUSIC THERAPY SERVICE CENTER "Nobody hates music. That's why it works. That's why we use it to discuss difficult issues with children, such as sex, public security, and even death."

Having touched thousands of lives, Wu Yulin says she's the lucky one.

WU YULIN, CO-FOUNDER YUELING MUSIC THERAPY SERVICE CENTER "People think we are helping others. I think it's quite the contrary. Often, I think these people have helped me grow from being a teenage intern to becoming a better and more independent person. They are the ones helping me and inspiring me to realize the joy of our existence, the joy of life."
