There was a report today revealing only 15% of Beijing university students can identify 'Tank Man', the protestor who stood in front of tanks during the Tiananmen Square massacre in 1989 and became an iconic image of the protests.
I was 13 when I watched BBC reporter Kate Adie reporting from the square, telling the world how the Chinese army opened fire on unarmed democracy protesters and the tanks rumbled over them.
It was one of the things which inspired me to become a journalist, because it made me think that if enough people have enough knowledge the world can change for the better.
A quarter of a century on, enough people in China still don't know enough about what happened. And the same people are still in charge of 1.3billion souls.
But the world has changed enough for people in China to access a website written by someone in London, if this post gets past its censors. And I'm proud to continue what Kate Adie started, and help to tell people what happened.
This is one of her reports from 1989.
