Of course searching in english is not going to prove anything.<p>Here is a Baidu search in chinese for "Tiananmen Square protests":
<a href="http://www.baidu.com/s?wd=%C1%F9%CB%C4%CA%C2%BC%FE" rel="nofollow">http://www.baidu.com/s?wd=%C1%F9%CB%C4%CA%C2%BC%FE</a>
It says "31 hits" (but it's actually 23)<p>And here is a Baidu search for "Tiananmen Square":
<a href="http://www.baidu.com/s?wd=%CC%EC%B0%B2%E9T%8FV%88%F6" rel="nofollow">http://www.baidu.com/s?wd=%CC%EC%B0%B2%E9T%8FV%88%F6</a>
 - 7.7 million hits.<p>You can translate keywords easily by using the wikipedia interlanguage links, which is what I did.<p>I bet that every single one of those 23 hits was tweaked and tuned to make the event sound like an irrelevant, small event in chinese history.
