The Great Firewall of China

Unknownthing, Fire wall of china.

You might have heard of “Great Wall of China” but there also exists “The Great Firewall of China”, not a physical barrier or wall preventing people from leaving, but it’s a virtual one, preventing information harmful to the Communist Party from entering the country.

The internet is not a globally unified entity. It’s seemingly international scope & scale only exists for certain parts of the world. There is another version of the internet that is largely separate from the global version:- The Chinese Internet or Intranet.

The Chinese internet seems like a closed virtual network deliberately separated from the world by the Communist great firewall that prevents any foreign website or information it deems unacceptable. The Chinese internet thus resembles more of a private internet or national intranet.

What China calls the “Golden Shield” is a giant mechanism of surveillance and censorship that blocks thousands of websites deemed harmful to the Communist Parties narrative and control, including YouTube, Facebook, Instagram and even Twitter.

What is Censorship

Censorship is the suppression of freedom of speech, public communication or some other information which may be consider harmful, politically incorrect, sensitive or inconvenient as determined by State of Control or Government.

Most recently Chinese govt was opened a investigation on Jack Ma and their company "Alibaba", because Jack Ma criticized Chinese govt bank policies ,that how they gives loan to start up and new business mans with high interest rate. 

Chinese govt strictly moniter their citizens ,That why you can't see any Chinese user on Facebook , twitter , Youtube or any other platforms you use, because these platforms not available in china. china don't share or disclose their any political news to others country. Also their news channels don't even says anything against their government.
