久溺深海冷不冷久居孤岛痛不痛
        
            [jiŭ nì shēn hăi lĕng bù lĕng jiŭ jū gū dăo tòng bù tòng]
        
        
            Literally, 'whether it's cold staying submerged in deep sea for long, and whether it's painful living alone on a lonely island'. This suggests a person feeling neglected, isolated and emotionally unfulfilled.
