若不是眠于九重海怎会待海枯不相见
        
            [ruò bù shì mián yú jiŭ zhòng hăi zĕn huì dài hăi kū bù xiāng jiàn]
        
        
            It comes from ancient Chinese poetry and it refers to eternal love where two people vow not to meet unless under impossible circumstances like 'till the sea runs dry'
