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 south-western 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.
But aftershocks, heavy snow on mountain passes, rain and the threat of disease have complicated relief efforts.
Thousands of children died when their schools crumbled around them, prompting widespread claims that corruption fatally compromised the buildings' strength.
Hundreds of distraught relatives placed wreaths along the road leading to Fuxing primary school in Wufu, where at least 127 children were crushed to death. They hoisted a banner reading, "The children did not die of a natural disaster but of an unsafe building."
"An answer must be given to our children," said Li Xiaoping, whose 11-year-old son was among the dead. "There is a problem with the buildings ... all the buildings here did not collapse except for this one building."
Li Rongrong, who heads the state-owned Assets Supervision and Administration Commission and is in charge of overseeing China's huge state sector, told a Beijing news conference that generally construction companies under him were very good.
But he added: "If these buildings (which collapsed) were built by major state-owned firms, we will take severe measures."
In Yinhua town, where more than 200 pupils died, a woman who lost her 13-year-old daughter said the school building had had two levels in 1993, but illegally added two more later.
"When it collapsed it was just fragments, not blocks. That shows how badly built it was," Luo Zaihong said.
