怀抱既然不能逗留何不在离开的时候
[huái bào jì rán bù néng dòu liú hé bù zài lí kāi de shí hòu]
This phrase means something like: 'Since embrace cannot last forever, why not when it's time to part?' Suggests acceptance of eventual separation, implying a bittersweet sentiment towards goodbyes in a romantic context or friendship, embracing what time together while understanding nothing stays indefinitely.
