BILL HEMMER, CNN ANCHOR: But first, have a look at "CNN 20" and today the issue: the fight for a voice in China.</s>MIKE CHINOY, CNN CORRESPONDENT: The man in front of the tank made a huge difference in terms of international perceptions of China. Even today, more than a decades later, I think that image, that moment remains for many people a defining moment in terms of how they look at China. What possessed this man to march out in front of a column of more than a dozen tanks and move from side to side to prevent these huge armored vehicles from crushing him: rage, bitterness, opposition to the government, who knows? Because we don't know, even today, who that man was. After five minutes of standing in front of the tank, several friends of his darted out into the street and hauled him away and then the tank column moved forward. And we may never know who he was or what was going through his mind. I have covered the country in the years since the Tiananmen crackdown. A great deal has changed. It is a much more open, much more liberal, much more free wheeling society in many ways than it was in 1989, except in a narrow political sense. So the image of the man in front of the tank carried a very powerful message about one side of Chinese reality.
