月亮代表我的心里有问题
[yuè liàng dài biăo wŏ de xīn lĭ yŏu wèn tí]
In Chinese pop culture, 'The moon represents my heart' comes from a love song where the moon symbolizes one's pure and unswerving heart towards love. Adding 'having problems' is used sarcastically or humorously to express that oneself may be troubled or in emotional distress, perhaps hinting at being affected deeply by something or someone, often in romantic context.
