他是我不能拥抱的太阳她是我不能温暖的月亮
[tā shì wŏ bù néng yōng bào de tài yáng tā shì wŏ bù néng wēn nuăn de yuè liàng]
This conveys feelings of admiration or longing from afar for two different people (a 'sun' and a 'moon'). The sun represents someone who can't be embraced (perhaps someone unattainable) and the moon is someone that cannot be warmed, indicating emotional distance.
