我把海都哭蓝了你还不来
[wŏ bă hăi dōu kū lán le nĭ hái bù lái]
'I Have Cried so Much the Sea Has Turned Blue But You Haven’t Come Yet': It symbolizes profound sadness over being left waiting or pining after someone. The depth and vastness implied by turning the sea blue show overwhelming yet fruitless feelings and expectations.
