China's Censorship Firewall Defeated

Censorship continues to be a big concern for China
A group of computer experts from the University of Cambridge claims that they are now able to circumvent the censorship mechanism that China uses to block unwanted content from reaching its citizens. Certain words are banned and certain websites are also banned. A user sitting within the country's network will not be able to reach websites for which the government has deemed inappropriate. China itself has
defended its right to police the Internet for its citizens
The group of researchers say that China's firewall is based on a a series of Cisco routers and the products work by censoring keywords. When a user wishes to access a websites that's banned, the router returns reset packets to the foreign website, severing the connection -- the data transmission is stopped at the foreign end-point. Using this bit of information on how the Cisco routers work, the researchers were able to find their way around the firewall by creating a system that ignores the reset packets sent by the Chinese routers.
Along with their discovery, the researchers also found that it was possible to create a denial-of-service (DoS) attack from within the firewall using the router's own blocking mechanisms. By masquerading the source IP address of a banned website to one that's within China's network, the researchers are able to ban users from within the network from accessing a Chinese government website for example.
Richard Clayton, spokesperson for the laboratory at the university told reporters that the researchers had reported the findings to the Chinese Computer Emergency Response Team.

You have to learn how to look at a big picture here.
Hilarious, seeing how you completely miss the bigger picture.

No son, I've been living in every possible society and environments, from poverty to being very very well off financially, from communism, socialism to capitalism and so called democracy, from having bombs and bombers fly over my head not knowing whether bombs will hit my building or not and I am living in the States today looking at everything that's happening.
I'm pretty sure that you really have no idea what's going on in the world today and why things are done the way they are done.
I would like to hear what is it that you consider a big picture. I didn't miss anything, I'm just a bit more experienced in the way things work in today's world.
