On June 5, 1989, one day after the Chinese army’s deadly crushing of the 1989 Tiananmen Square protests in Beijing, a single, unarmed young man stood his ground before a column of tanks on the Avenue of Eternal Peace. Captured on film and video by Western journalists, this extraordinary confrontation became an icon of the struggle for freedom around the world.
