According to a report by the AFP, Madam Zhang Weimin was planning a peaceful demonstration of hundreds of likeminded retirees in Shanghai, in November last year, when the Chinese authorities decided to put a stop to her campaign.
Zhang is the leader of a group of Shanghai residents -- now retired -- who was sent to the far western region of Xinjiang in the 1960s to work as part of a policy of dispatching so-called "educated youth" to rural areas.
Many have now returned from the eastern commercial city of Xinjiang, but they complain their pension and health benefits are much lower than other Shanghai retirees.
In April this year, Zhang was arrested by plain-clothes policemen for being an alleged ringleader, as she stood trail yesterday in a Shanghai court for "organising a crowd to cause a disturbance", a crime that carries a three to seven-year sentence.
A fellow protester, Lu Liying, 65, recounts her story with the Telegraph.
