High-school student Yang Liu, wearing a helmet given by a rescuer, has her legs are trapped under concrete in the rubble of a collapsed school in the township of Hanwang in Mianzhu city in Sichuan province May 14, 2008. Yang has been fed, given water and a white helmet as workers remove ruins brick by brick from around her and a crane pulled away slabs of concrete -- the remains of the school that parents said had around 800 students before Monday's quake hit.
