无论日后怎么走彼此依旧多年以后你还是我的旧友
[wú lùn rì hòu zĕn me zŏu bĭ cĭ yī jiù duō nián yĭ hòu nĭ hái shì wŏ de jiù yŏu]
Translated loosely as 'Regardless of how our paths diverge in the future, you will still be my old friend for years to come.' It conveys the wishful thinking and value attached by the person to lifelong friendship even if there's geographical or emotional distance over time.
