我又不是星星怎么闪动我又不是太阳怎么发光
[wŏ yòu bù shì xīng xīng zĕn me shăn dòng wŏ yòu bù shì tài yáng zĕn me fā guāng]
'I'm not a star; how can I twinkle? I'm not the sun; how can I shine?' This conveys a sense of inferiority or lack of self-worth, suggesting someone who doesn't feel they have any bright qualities to offer.
