我姓陈却沉不下爱你的心
[wŏ xìng chén què chén bù xià ài nĭ de xīn]
Translating to 'My surname is Chen but I can't help loving you', this expresses both an objective identity (being surnamed Chen) and also a deep, helpless emotion, meaning that despite everything he/she continues to deeply feel the weightless love for another person.
