According to the recent CNN publication (source: http://articles.cnn.com/2012-09-27/world/world_world-internet-freedom-report_1_internet-censorship-internet-freedom-jeremy-goldkorn)
Forty seven (47) countries impose Internet Censorship on their citizens, popular websites are filtered as “highly immoral” and unethical.
According to the report Chinese officials utilize very complex censoring system which allows them to build “Great Chinese Firewall”.
Most social websites have to comply with the Censoring rules and remove or block content which is defined as inappropriate to Chinese population.
Here is one workaround to bypass that kind of strict censoring of the Internet.
VPN will create an encrypted and protected tunnel. Since the data is encrypted inside the tunnel, the government won’t be able to see the contents and moreover to block traffic flows.
Use VPN and be happy with everyday Internet Surfing
