翻新 (fān xīn) is a verb meaning 'to renovate' or 'to revamp' — typically referring to restoring, updating, or modernizing a physical space or object, such as a building, room, or piece of furniture. The character 翻 (fān) carries the sense of 'turning over,' 'reversing,' or 'reworking,' while 新 (xīn) means 'new.' Together, they convey the idea of making something old become new again through structural or aesthetic renewal — not just cleaning, but substantial improvement or reconstruction.

This word is commonly used in construction, real estate, interior design, and urban development contexts. It implies intentional, often professional, intervention — for example, upgrading outdated plumbing, replacing flooring, or redesigning layouts. Unlike casual terms like 打扫 (dǎsǎo, 'to clean'), 翻新 suggests significant effort and investment. It can also be used metaphorically for refreshing concepts, brands, or systems — though literal physical renovation remains its dominant usage.
