(纪录片天安門 六四事件 Tiananmen Square protests)

The power struggles between students
The power struggles between politicians
The definition of democracy in China
The underlying factors that culmiated into the night of June 4th, 1989.

And more importantly, for our generation of people who care about our countries politics and wish, rather than to blindly shout out slogans like

DEMOCRACY!
or
JUSTICE!

Do look at what one is saying before clothing yourself with such problematic terms.
