Shot in one-minute increments, Ai's video obsessively documents daily life along Chang'an Boulevard, a thriving road that bisects the capital city along its east-west axis. ("Chang'an" literally means "long peace.") Ai and his team of videographers stopped at 50-meter intervals to record each fixed shot. The result is an impassive yet revelatory videologue that charts the blood flow of Beijing through its supermodern heart to its impoverished extremities.
