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.

He was locked in prison for committing a crime and lost his freedom.

shēn xiàn líng yǔ de rì zi ràng tā shēn kè fǎn sī zì jǐ de guò cuò。
The days spent confined in prison made him deeply reflect on his own wrongdoings.
