            [rén cháo zài xiōng yŏng nĭ què hái gū dān]
        
        
            'Crowds surge but you are still alone' depicts feeling isolated even when surrounded by many people. This reflects a sense of emotional loneliness, where the person may feel disconnected from those around them despite being physically close to many individuals.
