时光不散我们不老冰山不化我们不离
[shí guāng bù sàn wŏ men bù lăo bīng shān bù huà wŏ men bù lí]
Roughly translates as 'if time does not pass, we shall not grow old; if ice mountains do not melt, we will not part.' This expresses a desire for immortality and permanence in a relationship or friendship, wishing time would stop so nothing changes and separation never comes.
