In China, ice climbing is growing in popularity, especially among the young. Zhang Zefeng reports.

Armed with ice axes and crampons, climbers scale a 25-meter-high frozen waterfall. Their bodies are supported only by their equipment. And below them lies a frozen lake stretching across the base of a mountain.

You may think that this is a scene from an adventure movie like Touching the Void or Meru, but this is what a group of thrill-seekers experienced at an ice climbing competition on the outskirts of Yunmengxia Valley, Miyun county, in Beijing, over Feb 11-12.
