A man holds up a candle during a candlelight vigil at Hong Kong's Victoria Park June 4, 2009 to mark the 20th anniversary of the crackdown on the pro-democracy movement in Beijing's Tiananmen Square in 1989. Cradling candles, laying wreaths and clad in black or white, Hong Kong residents transformed a downtown park into a speckled sea of flickering lights, in remembrance of the hundreds of pro-democracy demonstrators and students crushed by tanks and troops near the square two decades ago.
