Twenty-five years ago, the Chinese government ordered the military to clear Tiananmen Square of pro-democracy protesters, killing hundreds or thousands. Today, any discussion of the event is heavily censored in China, with people using coded language like "May 35th" to talk about the "June 4th" military crackdown. The Chinese government has successfully removed accounts of the massacre from history books and the Internet, leaving many young people unaware of what happened. Discussing the event can still result in punishment, as the government works to erase the protests from history and prevent opposition from gathering either publicly or online.
