Blue Sky Rescue Team is China's largest non-governmental humanitarian organization, established in 2007.

The rescue team has set up 31 branches around China. More than 30,000 volunteers were registered nationwide, drawn from every walk of life.

The team's primary tasks are search-and-rescue, information screening, medical assistance and water supply, as well as epidemic prevention.

During the Wenchuan and Nepal earthquakes, they provided assistance and support, as an important component of rescue forces.

We interviewed Zhang Yong, leader and founder of the team, to let him tell us about the story of BSR behind the scenes.
