[Change & possibility](https://chinese-idioms.yudis.dev/idioms/topics/change)

## When to use it

Use to reflect on profound transformations in the world or a place.

It is more literary than ordinary talk about a small recent change.

## Understanding the expression

The sea and cultivated land differ so greatly that one replacing the other presents change on an immense scale. The idiom often looks back across years or generations. It can describe landscapes, communities, or human circumstances transformed beyond recognition. Its literary tone makes it suitable for reflection. A minor redesign or a day's changing weather normally lacks the scale the image suggests.
