对于回忆勿忆对于思念勿念
[duì yú huí yì wù yì duì yú sī niàn wù niàn]
Literally translated, it goes as 'Don't remember about the memories and don't miss about the nostalgia', suggesting not to dwell on the past or the things/people you've missed. Reflecting that user tends not to linger on those gone-by days or people/affections lost but focus more on present moment and life itself instead.
