图书馆钉子户

• Pinyin: tú shū guǎn dīng zǐ hù
• Hanzi breakdown: 图书馆 is library; 钉子户 is a fixed holdout, here used metaphorically.

Meaning

Someone who practically lives in the library because they study there so often.

图书馆钉子户 borrows 钉子户, a holdout resident, to joke that a student has become fixed in the library. It is usually self-mocking or admiring, not a legal or property term in this context.

2. 她固定坐三楼角落，像图书馆钉子户。 She always sits in the corner on the third floor, like a proper 图书馆钉子户.
