A young woman poses for a photo on a railway that passes through a former metallurgic plant in Xi'an, in Northwest China's Shaanxi province, Aug 13, 2014. Friction from running trains against the greenery on the sides of the tracks has carved a tidy green tunnel in between the dense woods along the rail. That's led to an exceptional scene that attracts people who want to take pictures. [Photo/CFP] |
