As the sun rises at Tiananmen Square, protesters build a 10-meter (33-foot) Goddess of Democracy statue out of foam and paper-mache over a metal armature. In the early morning of June 4, soldiers backed by tanks and armored cars toppled the statue, which had stood directly facing the Mao portrait at the Forbidden City.

Later that night, the 38th Army would open fire on unarmed civilians overtaking the occupied Tiananmen Square.

Thousands of protesters surround a bus with a display of captured weapons just days prior to the crackdown.

On the late evening of June 3, protestors set fire to an armored personnel carrier on the Chang'an Avenue near Tiananmen Square.

On June 4, a truck manned by People's Liberation Army troops patrol down the Chang'an Avenue in front of the Beijing Hotel the day after the bloody crackdown on student-led pro-democracy supporters.
