你离开后那些誓言还有用吗
[nĭ lí kāi hòu nèi xiē shì yán hái yŏu yòng ma]
Translates as 'Are those vows still useful after you left?' This implies that all promises and commitments become worthless once someone leaves. The user probably has some unresolved issues from the past about failed promises or betrayals that made him question the real value and reliability of such vows.
