HONG KONG - JUNE 04:  Thousands of protestors hold candles during a candlelight vigil for the 19th anniversary of June 4 Tiananmen Square Massacre in Beijing and also for the victims of the Sichuan earthquake, at Victoria Park on June 4, 2008 in Hong Kong, China. Pro-democracy activists reiterate the pleas for those who ordered the massacre to be held accountable, for the release of dissidents still incarcerated and for the vindication of the pro-democracy movement of 1989. They also called for democracy to be realised by ending the one-party dictatorship in China.  (Photo by MN Chan/Getty Images)
