A 19-year-old woman from Hubei who broke her back while trying to escape from a prostitution gang in Guangzhou will undergo surgery tomorrow morning after 50,000 yuan donated by South China Morning Post readers to fund the operation was paid into a hospital account yesterday. Chen Deping thanked Post readers from her Guangzhou hospital bed and said she would try to recover as soon as possible to show her appreciation. Readers had donated $353,625 by yesterday morning, more than is needed to fund the operation and Ms Chen's rehabilitation, contribute to her living expenses and pay for a follow-up operation next year. The Post is now looking for suitable charities to receive the excess money donated so that other people can be helped, and is open to suggestions.

She injured her back after jumping from the fifth floor of an apartment in Guangzhou on June 1 after being tricked into coming to the city, then raped and forced into sexual slavery by a criminal gang. Li Guitao, the surgeon who will perform the operation, said the surgical team had needed 'some time to do preparations'. Dr Li said doctors planned to insert six metal pins and three metal rods in Ms Chen's lumbar vertebrae to repair her damaged spine. The operation is expected to last about five hours, starting at 8am. Ms Chen should be able to stand and walk two weeks after the operation but a full recovery will take a year. The pins must be removed in a second operation next year, after which Ms Chen will be able to resume a normal life.
