回忆是一种过期的唯美期待是一种假装的幸福
[huí yì shì yī zhŏng guò qī de wéi mĕi qī dài shì yī zhŏng jiă zhuāng de xìng fú]
The phrase conveys the idea that 'memories are expired beauty and expectations are feigned happiness.' This suggests that while memories were once beautiful, they fade with time and lose their value, and expectations can only lead to a pretended sense of happiness.
