Profile: Feathers of the Heart

Hu Zongqiang, 40, is an airplane mechanic at an Air China maintenance base in Tianjin. But his work goes far beyond that of a regular maintenance technician.

Since October 2012, Hu's voluntary work team has been raising money for newborns with biliary atresia, a life-threatening liver disease, whose families are too poor to pay for medical treatment.

To date, Hu's team, called Xinyu, or Feathers of the Heart, has raised approximately 3 million yuan ($484,000), which has helped to pay for 34 babies to have liver transplants.
