曾经的美好只是泡沫
[céng jīng de mĕi hăo zhĭ shì pào mò]
This username implies that what was once cherished and considered beautiful in the past has turned out to be fleeting, transient, or even insubstantial – like a soap bubble, dazzling for a moment before it bursts and disappears. It suggests feelings of regret or disillusionment about past experiences or memories.
