With an increasing number of people seeking thrills in the great outdoors, injuries and even deaths are climbing. Jiang Xueqing looks at how teams step up to help.

While climbing the Tiger Leaping Gorge in Lijiang, Yunnan province, on Jan 21, a 26-year-old United States man tumbled and broke his neck and skull.

He was rushed to the Lijiang People's Hospital, but it was too small to perform the difficult surgery he needed and his friend called the Beijing alarm center for International SOS for help.
