贝多芬谈不出姐的悲伤
        
            [bèi duō fēn tán bù chū jiĕ de bēi shāng]
        
        
            Even Beethoven Couldn’t Compose Sister’s Sadness. An allusion to Ludwig van Beethoven, suggesting that no matter how skilled or great at expressing emotion (through music), even a genius like Beethoven couldn’t fully understand or express the deep sadness the owner feels.
