[Effort & growth](https://chinese-idioms.yudis.dev/idioms/topics/effort)

## When to use it

Praise ready eloquence or a gift for verbal composition.

Fluency alone does not guarantee accuracy or clear reasoning.

## The image & its use

Some speakers can form a graceful explanation or a short poem without first writing a draft. This expression praises that readily available verbal skill. The words seem to take an organized, polished shape as they are spoken. It can suit a storyteller, a practiced presenter, or someone with a strong command of language. Preparation and extensive reading often support such ease. When the subject involves factual claims, the speaker still needs to distinguish eloquent delivery from information that has been checked.
