你的微笑映在我回忆终点
[nĭ de wēi xiào yìng zài wŏ huí yì zhōng diăn]
This could translate to 'Your smile is reflected at the end of my memory', meaning this person's mind ends at the moments with another's happy expression. This often appears to express longing for good memories, perhaps hinting towards past relationships, friendship, or even general nostalgia.
