我姓郑却挣不到爱你的资本
[wŏ xìng zhèng què zhēng bù dào ài nĭ de zī bĕn]
'My surname is Zheng but I can't make the money to love you properly.' Here, it uses a pun on surname 'Zheng' to mean 'make' or 'earn'. It shows financial struggle as a barrier to expressing love fully, reflecting frustration and limitation in material terms.
