我姓郑却不能争取到爱你
[wŏ xìng zhèng què bù néng zhēng qŭ dào ài nĭ]
'My surname is Zheng but I can't get love from you'. The meaning here carries regret and helplessness - though the user has the will to fight, circumstances might have constrained them such that they feel unable to achieve love despite wanting it intensely.
