十天很短你们久留十年很长你们别走
[shí tiān hĕn duăn nĭ men jiŭ liú shí nián hĕn zhăng nĭ men bié zŏu]
Translates to “Ten days are short for staying, ten years long for bidding farewell”. Conveying mixed sentiments of wishing to extend good times longer yet realizing time inevitably passes, highlighting both the preciousness of shared memories as well as melancholy over endings and departure.
