China vowed on Wednesday to deal severely with anyone found responsible for shoddy state building work, as parents demanded to know why last week's earthquake destroyed so many schools, killing thousands of children. Nine days after the massive tremor hit mountainous Sichuan province in southwestern China, rescuers were still finding survivors. A woman was pulled alive from a tunnel at a hydropower plant in the town of Hongbai, state media reported. The number of dead and missing rose to more than 74,000, with a further 247,000 hurt.
