qiáng 墙

Without the use of special bypassing methods, Facebook, as well as YouTube and Twitter, are blocked by the Great Firewall of China.

A reference to the Great Firewall of China used in several subversive netizen-created terms.

In Mandarin, "wall" (qiáng 墙) sounds the same as the word "strong" (qiáng 强). The character for "strong" is a component in a number of Chinese words. To make reference to the Great Firewall of China, netizens often substitute the character for "strong" with the character for “wall.” Common examples can be seen in the words "wall nation" and "wall raped."
