海是一座无城的墙鱼是一缕未亡的魂
[hăi shì yī zuò wú chéng de qiáng yú shì yī lǚ wèi wáng de hún]
Using metaphors, this nickname conveys the idea of freedom and confinement coexisting simultaneously: like a vast sea being a boundary without walls, and a fish representing an eternal spirit beyond death. It could reflect on themes of isolation, boundless possibilities, and transcendence over mortality.
