The Chinese word for crisis is made of 'danger' and 'opportunity'.

No. The claim that the Chinese word for crisis is made of "danger" and "opportunity" is a myth. The word is 危机, wēijī. The first character, 危, does mean danger. The second, 机, in this word means an incipient moment or a crucial point. It does not mean opportunity. Opportunity is a different word, 机会, jīhuì, which only shares the syllable. Victor H. Mair states the false sum in a line of his own: "danger + opportunity ≠ crisis." The characters are real. The equation is not.

The English story has a paper trail, and the trail does not begin in a classical dictionary. It has been traced to a missionary journal in 1938. John F. Kennedy popularised it in campaign speeches in 1959 and 1960. A crucial point can be dangerous without hiding a chance inside the word. If you teach 危机, teach danger and the incipient moment, and teach 机会 separately when you mean opportunity. Leave the sermon out of the definition. The myth is modern English, not a piece of Chinese wisdom.
