A social media crackdown is underway for this 25th anniversary of the pro-democracy uprising in Tiananmen Square. Foreign journalists have been harassed as they try to cover the anniversary in Beijing. We look, too, at what became of 'Tank Man'? A student, thought to be 19 year-old Wang Weilin, stood alone against the might of the Chinese army on the 5th of June, 1989 becoming a symbol of the desire for freedom and democracy.
