In 2016, Du Xintong was a broadcasting major at Shaanxi University of Science and Technology when she met a girl who was recovering from cleft lip and palate surgery at a children’s hospital in Xian, northwest China.
The young girl was quiet and unwilling to talk because she was unable to speak clearly. To communicate with her, Du wrote questions instead, and the pair conversed about the girl’s name, age and favourite things.
When the time came for Du to leave, the little girl tentatively used her voice. “Will you come tomorrow, sister?” she asked.

“This voice touched me. This was the first time I heard the voice [of a child] with speech impairment,” Du says.

Unable to get the girl’s predicament off her mind, Du began researching more about cleft palates and started recruiting student volunteers and collaborating with hospitals to help other children.
