眼睛成海却未蓝
[yăn jīng chéng hăi què wèi lán]
It means something similar to 'Eyes have seen much like an ocean but haven't turned blue', using the vastness of seas but not having its typical color. This could symbolize seeing or experiencing things widely or deeply, without being transformed or losing oneself in the expected way. It could reflect an emotional state or personal view on one's experiences.
