我只是一座没有城墙的岛
[wŏ zhĭ shì yī zuò méi yŏu chéng qiáng de dăo]
'I'm just an island without walls'—a poetic analogy describing oneself as an isolated entity that is open and vulnerable without protection against external influences. The metaphor of 'an island with no wall' signifies an identity separate from the crowd but defenseless and susceptible to changes brought by waves coming from all sides.
