Cooperation, Western Proverb

It takes two to tango.

- Western Proverb

A common idiomatic expression which suggests something in which more than one person or other entity are paired in an inextricably-related and active manner, occasionally with negative connotations.

The phrase originated in a song, Takes Two to Tango, which was written and composed in 1952 by Al Hoffman and Dick Manning. The lyrics and melody were popularized by singer Pearl Bailey's 1952 recording.

탱고 추는 데는 둘이 필요하다.

- 서양속담

두 손뼉이 마주쳐야 소리가 난다.

China, Winston Churchill

The Chinese said of themselves several thousand years ago: "China is a sea that salts all the waters that flow into it". There's another Chinese saying about their country which is much more modern—it dates only from the fourth century. This is the saying: "The tail of China is large and will not be wagged". I like that one. The British democracy approves the principles of movable party heads and unwaggable national tails. It is due to the working of these important forces that I have the honour to be addressing you at this moment.

- Winston Churchill, address to a joint session of Congress, Washington, D.C. (January 17, 1952); reported in Winston S. Churchill: His Complete Speeches, 1897–1963, ed. Robert Rhodes James (1974), vol. 8, p. 8326.
