**Register:** Literary · comparative

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

## When to use it

Usually use negatively to contrast a person's present growth with former limitations.

Common in 不再是; it does not simply mean any accomplished person.

## Understanding the expression

The phrase names a figure remembered as having improved through learning. In modern use, it commonly appears when saying that someone is no longer the uninformed or inexperienced person they once were. The contrast is essential: study and practice have changed the person's abilities. It can be affectionate or teasing, but using it directly to belittle a beginner may sound condescending. Emphasize growth rather than treating the old label as permanent.
