MBtv: Museum in Hong Kong showcases dark Tiananmen memories

It was June 4, 1989 when Chinese tanks and soldiers crushed student-led pro-democracy demonstrations in Beijing. Hundreds were killed and by some estimates more than 1,000. As the 30th anniversary of the Tiananmen Square crackdown approaches, a museum has reopened its doors in Hong Kong, aiming to remind people of the bloody incident.
