淹死在水里的鱼
[yān sĭ zài shuĭ lĭ de yú]
Translates literally as 'a fish drowned in water'. Fish typically live in water, but a drowned fish contradicts common understanding, indicating paradoxical circumstances or emotions where a normally supportive element has become adverse. It conveys feelings of being lost and suffocated within the usual safety and comfort.
