Isn't a Chinese gang a "triad" and not a gang of four?

Whilst triad is a generic reference used in the West to describe Chinese organised crime gangs, The Gang of Four (simplified Chinese: ËÄÈË°ï; traditional Chinese: ËÄÈËŽÍ; pinyin: S¨¬r¨¦n b¨¡ng) was a political faction composed of four Chinese Communist Party officials. They came to prominence during the Cultural Revolution (1966¨C76) and were later charged with a series of treasonous crimes. The gang's leading figure was Mao Zedong's last wife Jiang Qing. The other members were Zhang Chunqiao, Yao Wenyuan, and Wang Hongwen.

With access to the internet, there is no reason to ask silly questions like yours.

Did anyone notice the rhyming?

Wow... impossible, brilliant, different

I couldn't find the groups, but figuring out the links was very enjoyable.

Very tough but tantalisingly I found a couple of groups of three but not the fourth. Different as well as difficult.

Tenuous links and questionable clues.

Agree with all the positivesbelow, excellent - more please
