年限

• Pinyin: nián xiàn
• Hanzi breakdown: 年 = pictograph of harvest/year; 限 = 阝(mound/hill) + 艮(to stop/limit) — a boundary or limit

Meaning

A fixed number of years; a specified time limit measured in years. Refers to a term of service, the service life of a product, or a statutory time requirement.

Common in legal, administrative, and technical contexts. Key collocations: 使用年限 (service lifespan), 工作年限 (years of service), 建筑年限 (building lifespan), 保质年限 (shelf life in years). Differs from 期限 (deadline/term), which can refer to any time unit — 年限 always implies a count of years.

Examples

1. 根据相关法规，该类建筑的设计使用年限不得低于五十年，施工单位必须严格达标。 Under the relevant regulations, this type of building must be designed for a service life of no less than fifty years, and the construction unit must meet the standard strictly.
2. 这款工业设备的正常使用年限为十年，超期使用存在安全隐患，建议定期更换。 This industrial equipment has a normal service life of ten years; using it beyond that creates safety risks, so regular replacement is recommended.
3. 招聘公告明确要求应聘者须具备五年以上的相关工作年限，否则不予受理简历。 The job posting clearly states that applicants must have at least five years of relevant work experience; otherwise their resumes will not be accepted.
