Nineteen-year-old Tang Wenyan lies on a Guangzhou hospital bed, out of breath after being helped to the toilet. She is 1.6 metres tall and weighs only 25kg.
She is paralysed and can barely use her hands. Twelve other women who used to work for the Anjia Shoe Factory in Dongguan are in the same hospital.
All are suffering the effects of benzene poisoning.
The Anjia women's story made national headlines last week after the company tracked down the ill migrant workers and sent them to Guangdong Occupational Disease Treatment Centre in Guangzhou.
The women are from Guizhou, Henan, Sichuan and Hubei provinces.
The case has raised awareness of the mainland's poor record on occupational health and the lack of government supervision of workplaces.
