Tang Hui sobs as she embarks on the bus journey home in Yongzhou of Central China's Hunan province. The photo is taken in Changsha, capital of the province on Aug 11, 2012. Local authorities released Tang from a labor camp on Friday, where she was ordered last week to serve an 18-month term for "disturbing social order and exerting a negative impact on society." Tang was challenging the sentences handed down to the men who abducted, raped and prostituted her 11-year-old daughter. Tang's case triggered a public outrage questioning the local justice system. Authorities also said they would investigate Tang's claim that police falsified evidence in her daughter's case. [Photo/Xinhua]
