Strike while the iron is hot意思
"Strike while the iron is hot" is a proverb that means to take advantage of a good opportunity immediately, while the chance is still there. The idea behind the phrase is that if you wait too long, the iron will cool down and become harder to shape, just as a good opportunity can pass if you don't act on it quickly.
The proverb is often used as a piece of advice to encourage people to be proactive and seize the moment when a favorable situation presents itself. It is a reminder that opportunities, like a hot iron, can cool down and become less effective or even lost if not acted upon in a timely manner.
