囹圉
líng yǔ
variant of 囹圄[ling2 yu3]
enclosure (囗) + enclosure (囗) = prison, a place of confinement
Both characters share the enclosure radical 囗, visually evoking walls closing in on all sides. 令 and 幸 contribute sound rather than meaning here; the doubled 囗 carries the full weight of captivity.

tā yīn fàn zuì bèi guān jìn le líng yǔ。

那个人在囹圉中度过了很多年。
nà ge rén zài líng yǔ zhōng dù guò le hěn duō nián。
That person spent many years inside prison.
