念不完我的哀愁落不尽我的思念
        
            [niàn bù wán wŏ de āi chóu luò bù jĭn wŏ de sī niàn]
        
        
            'Unending sorrow cannot be completely lamented, endless yearning cannot be entirely expressed' expresses deep sorrow and ceaseless longing for something or someone that remains unresolved.
