How it's used

Emphasizes the entirety of a person's life, often carrying a tone of exaggeration or frustration. It is frequently used to highlight a long duration of time that feels stagnant or unchanging. When used in questions, it often implies disbelief or a challenge regarding someone's long-term commitment to a situation.

Examples

He has never been on a trip in his whole life, it is so sad.
Do you plan on doing this job for your entire life?

Common phrases

one's whole life

Common mistake

Do not confuse this with 一世, which is more formal or literary. 成世 is strictly colloquial and carries a more personal, emotive weight, making it sound more natural in casual conversation than the standard 一世.
