I don't really know the situation in China, but surely with the amount of proxy servers and suchlike, there has to be ways to get to the rest of the internet?
I'm sure there's some stuff blocked to most people, but anyone clued up must get full access?
Or are their stupidly harsh penalties like jail for circumventing the blocks?
Also, surely most of China does end up knowing about its own history and its own political, social and economic stances, etc? To me, if I knew of Tiamenen Square and went to look it up, and found no mention of it online, just a message saying 'due to laws some results can not be shown', I'd just know my country was ashamed of its history.
Now of course, just about every country has done some terrible things, but putting fingers in ears and going 'lalala we can't hear you' is not really a productive way to deal with it.
Like I say, I'm commenting thru ignorance in the main, maybe most of China's population doesn't know about history and Tianemen Square is just known as a nice place to go for a picnic, it's just very strange from a western perspective is all.
