Tiananmen Square anniversary: China's voices of dissent

Twenty-three years after the massacre at Tiananmen Square, Chinese authorities continue to suppress the memory of it - and those who call for democratic reform.
The country is preparing for its once-a-decade shuffle of its top leaders, with the last leaders from the Tiananmen era due to retire. But there is little hope for political change.
