Tightrope walker Zhang Liang walks on a thin rope at an abandoned construction site in Beijing, Jan 26, 2013. Tightrope walking, often using a 2.5mm-wide, 3mm-thick nylon rope, is a challenging outdoor activity not for the faint-hearted. Zhang Liang performs a series of stunts on the rope and has successfully walked 150-meters along the rope distance. He is now planning to walk the line at a 200-meter height.
