我说好久不见你说久别重逢
[wŏ shuō hăo jiŭ bù jiàn nĭ shuō jiŭ bié zhòng féng]
The phrase translates to 'I say we haven't seen each other in a long time; you say it’s a reunion after a long absence'. It illustrates the differing perspectives on the passage of time between two people. One feels it's been too long, while the other is focusing on their joyful reconnection.
