Jun 5: Finding the meaning and memory of Tiananmen 20 years on

The Tiananmen candlelight vigil in Hong Kong, held faithfully every year for the past 20 years, is the only place on Chinese soil where people publicly mourn and commemorate the June 4, 1989 crackdown on pro-democracy students. It is also the only place where people can debate and ponder the legacy of Tiananmen and ensure the events of that year are never forgotten. Produced and edited by Edward Cheng
