我姓刘却留不住要走的你姓张却没长出你爱的模样
[wŏ xìng liú què liú bù zhù yào zŏu de nĭ xìng zhāng què méi zhăng chū nĭ ài de mó yàng]
Means ‘I am surnamed Liu, and I can’t keep you who wants to leave; you are surnamed Zhang, but did not turn into what you love’. This signifies feeling helpless about losing someone you care about, especially due to lack of personal change or appeal.
