Today's date won't show up.
You can search "June 4th" or "Jun 4th" and results will not come up. You can try with Chinese characters, or in their Pinyin transliteration, or in English or even French and the result will not appear on your screen.
Even "today" won't work. Nor "tomorrow."
June 4, the anniversary of the 1989 Tiananmen Square massacre is again keeping censors busy in China.
As in past years, there is a long list of words that people in China are blocked from searching on Weibo (the Chinese version of Twitter) around the time of the anniversary of the bloody incident.
According to a compilation from the Citizen Lab, at the University of Toronto's Munk School of Global Affairs, this year's banned search keywords include various combinations of the numbers 6, 4, 8 and 9.
Search terms such as "Tiananmen," "square," "tank" and "Changan Avenue," which leads to the central square, and names of leaders of the 1989 protests were obviously blocked.
But Citizen Lab researchers found that even Roman numerals for 6 and 4 ("VIIV"), or the mixing of numbers and letters such as "8q b 4" (89 6 4) or other ways to describe June 4, such "May 35" or "April 65th."
Another anti-censorship website reported that at times the authorities tried a more fine-tuned, filtered approach, allowing only some search results to come through.
By the date of the anniversary, the Chinese characters for "yesterday," "today," and "tomorrow" were also blocked, according to China Digital Times, a watchdog website based in California.
The censorship also applied to anything that could be construed as a way to commemorate the massacre of pro-democracy protesters in Beijing's central square.
Queries about black clothes were blocked, as were candle emoticons.
Still, some managed to sneak through a reference to the crackdown.
Buzzfeed reported that, three days ago, a Chinese web portal, NetEase.com featured a photo gallery of children toys. In the middle of the slideshow was a Lego recreation of the iconic photo of "Tank Man," the protester who tried to stop a column of tanks heading into the square.
