曾经的美好只是现在的回忆
[céng jīng de mĕi hăo zhĭ shì xiàn zài de huí yì]
Translated to 'Once beautiful memories are only memories now,' this name expresses deep feelings of nostalgia and sadness about good times that have passed. It conveys the sentiment that while things used to be perfect or blissful, they can never return as they were before.
