My friend in QQ told me that she couldn’t access facebook with her phone,’cause FB is still retricted in china. Then I try to find the solution with some effort and research here’s the result ..

Accoding to all facebook.com, The Chinese government simply doesn’t let requests to Facebook.com be processed. Its really that simple to block Facebook. However, this level of control requires a sophisticated, large scale effort to accomplish.

China’s control over its Internet infrastructure is so complete that Internet packets addressed to Facebook servers are routinely deleted. China’s government is open about the fact that it inspects Internet traffic that 1) comes in and out of the country and 2) that travels around in the country. China uses sophisticated technologies like Deep Packet Inspection (DPI), where Internet routers analyze, drop and even save Internet packets – instead of simply passing them along (as they normally do).

China’s government control over information is not just technological – its economic. China’s government exerts control over every significant business in the country. Companies in China must be majority owned by a Chinese citizen, and even then are heavily regulated by the government. All the major corporations in China, including telecommunications and media companies, are state owned entities or are majority owned by the state. This exerts a significant level of state influence on how people receive and send information.

How  could chinese user access Facebook and others blocked site ?

Using different proxy, you can try a variety free VPN to access blocked site, you can try using vtunnel. Simply access vtunnel.com or https://vtunnel.com it can help you get around blocks at schools or work as long as it not blocked. All you have to do just go to the website see the input at the top, try to change the desired website (http://www.facebook.com) and click begin browsing. If vtunnel is blocked go to freeproxies.org find the the list free proxies you can try. The s on the end of http makes it load a secure version of the website that is harder for the schools/ company to block and is usefull once they block vtunnel.

But it’s not guarantee that you can access facebook or other blocked site 100% , it also depends on the free VPN itself. If you really want to access all site without getting blocked use payed VPN like http://www.surfbouncer.com/unblock_china…

I didn’t try it in China yet so Hope it works 🙂
