壹笑傾城壹哭傾城
[yī xiào qīng chéng yī kū qīng chéng]
It translates to 'A Smile Can Enthrall the City; A Tear Can Also'. This is from ancient Chinese ballads, where a woman so beautiful that her expressions - both happy and sad - captivated an entire city. Thus, this nickname might express someone feeling or believing they possess charming beauty that moves others around them significantly
