Fifteen years ago, China witnessed huge protests and calls for change, before these were brutally crushed by tanks around Beijing's Tiananmen Square.
Chinese soldiers began clearing Tiananmen Square early on 4 June
The BBC's Chinese Service has interviewed some of those who witnessed the protests and subsequent bloodshed.
Ma Shao-fang was one of 21 students who was later pursued by the Chinese Government. He was imprisoned for three years and now lives in Shenzhen.
It is very difficult for me to forget two events that happened at the time - one during the night of 3 June and the early hours of 4 June, and the other on the day of 4 June.

And then later there was a bit of confusion during our retreat that suddenly turned into great chaos.
People were shouting "sit down, sit down". I was in the front row. The soldiers' bayonets were against my chest and the chests of Liang Zhao Er and Yang Zhao Hui.
