China spent 37 years making sure its own people never see this footage. Days after the June 4 massacre, a British ITN crew secretly filmed Beijing under occupation. Military convoys on the streets. Barricades. Soldiers in the middle of daily life. China was confiscating film from foreign journalists at the time, and much of what ITN shot never aired. The restored tapes are now online and spreading again. Inside China, the images stay scrubbed from the internet. Many young people there have never seen the Tank Man photo. A generation is growing up in China without ever seeing it.
