蔚蓝的海是鱼的泪
[yù lán de hăi shì yú de lèi]
'Wei Lan De Hai Shi Yu De Lei' means 'The Deep Blue Sea is Full of Tears Shed by Fishes'. Here, fish’s tears metaphorically depict sorrow submerged in depth - an unseen, profound sadness which matches with melancholy blue seas. Perhaps they experienced hardships in silent and are choosing ocean depth to express those concealed emotions, indicating inner pain hidden under surface calmness.
