我姓白却摆不出你的心我姓陈却衬不出我的爱
[wŏ xìng bái què băi bù chū nĭ de xīn wŏ xìng chén què chèn bù chū wŏ de ài]
This nickname plays on surnames ('Bai' 白 can mean 'white' and also sounds like 'arrangement,' 'Chen' 陈 sounds like 'adorn'). It conveys frustration: someone surnamed Bai cannot show another’s heart, while someone surnamed Chen finds it hard to express their love.
