Here's a Chinese idiom which always tripped me up. I could never remember or use it...

But as soon as I learned the visual meaning, it totally stuck and now I use it all the time!

Here's the idiom:

"Firm and decisive, resolute" (斩钉截铁 zhǎn dīng jié tiě)

Break it down literally:

• "chop through nails" (斩钉)

• "slice through iron" (截铁).

The image is a blade so sharp and a strike so committed there's no hesitation, no resistance, and no going back.

In other words totally resolute and determined.

Background: the idiom first appears in Jingde Transmission of the Lamp (景德传灯录), a Song Dynasty collection of Zen Buddhist texts, where it described the decisiveness of a monk's practice....

"As decisive and chopping through nails and slicing through iron"

Now in modern Chinese...

It's used to describe the way someone speaks or acts. Or when a person gives you an answer with zero ambiguity.

Use it for: decisive verdicts, unambiguous instructions, people who don't do "maybe."

Example:

She didn't hesitate for a second — her answer was final. 她斩钉截铁地说不行，没有任何商量的余地。

Now you've got that image in your head, why not give it a go today!
