他是星星我摸不到她是月亮我触不着
[tā shì xīng xīng wŏ mō bù dào tā shì yuè liàng wŏ chù bù zhe]
This translates to 'He is the star I cannot reach; she is the moon I cannot touch.' It expresses a deep sense of longing or unattainable desires where both personal connections and emotions feel distant and unobtainable.
