[Perspective](https://chinese-idioms.yudis.dev/idioms/topics/perspective)

## When to use it

Emphasize a well-supported condition or confidence in stability.

An emphatic comparison does not remove the need for ordinary checks.

## The image & its use

A large mountain offers a familiar image of steadiness. This expression compares a secure arrangement or position with that stability. It may reassure someone after a careful preparation or describe a structure that is well supported. The phrase is emphatic rather than a technical assessment. A practical explanation should identify the support, checks, or conditions that justify confidence. Even a stable arrangement can need maintenance when circumstances change, so the compliment should not become a reason to ignore new information.
