趁热打铁用英语怎么说？

"Strike while the iron is hot" is the correct English expression for "趁热打铁" in Chinese. This phrase suggests taking advantage of an opportunity at the right time or seizing the moment. In a literal sense, when forging iron, it is easier to shape and mold the metal when it is hot. Similarly, in life, when an opportunity arises, it is best to act promptly and not let it cool down. Just as hot iron cools and hardens, opportunities may slip away if not acted upon. Therefore, it is essential to be attentive and agile enough to exploit favorable circumstances.
