Activists remember Li Wangyang one year after he was found hanged in hospital ward
March to central government's liaison office and a vigil demand justice for late Hunan dissident

Hong Kong activists yesterday demanded justice over the death of Tiananmen dissident Li Wangyang a year ago, and an end to the suppression of his family, who are being kept under close watch at their Hunan home.
Cable TV reporter Chris Lam Kin-seng, who interviewed Li weeks before he died, also called on Hongkongers to remember Li's firm belief in democracy for China.
Li was jailed for 21 years after organising protests in Hunan to support the student movement in Beijing in 1989, just before the Tiananmen crackdown.
Although he was left blind, deaf and barely able to walk from being tortured in prison, he remained defiant in fighting for his cause in the years before he died.
Li was found hanging in a Hunan hospital ward on June 6 last year.
A report by the provincial authorities a month later said he had hanged himself, but the account has been widely doubted.
