June 4 is remembered as the day the Chinese government brutally shut down a peaceful demonstration in Tiananmen Square in Beijing that was calling for reforms in the ruling Communist Party and in the government.
One of the most famous scenes is the lone man with shopping bags standing up to a column of tanks.
While no official death toll has been released by the Chinese government, estimates are that hundreds died in the army attack on the demonstrators. An additional 10,000 or so were arrested.
Each year in Hong Kong there is a major commemoration ceremony — the only place in China that has such a thing, thanks to the protection of civil rights enshrined in the handover treaty of 1997.
Also each year the Chinese government tries to censor any reference to June 4 or the demonstration. And each year it fails, because the Netizens of China stay one step ahead of censors.
One of the earliest work arounds was a call to honor the dead of May 35. Or Remember the Square of 8. (For the math-phobic, 8×8=64 and 64=June 4)
The good people at China Digital Times have been keeping track of the code words and phrases the Chinese censors have banned on the Internet. One of the more humorous items is how the ban on “64” caused reporting on the Shanghai stock market fell 64.89 points. (Yes, that looks like 6/4/89) Rather than risk anyone thinking it was a Tiananmen remembrance, the government doctored the stock report for public consumption.
