烟花再美只是瞬间乀爱情再美终究短暂乀
[yān huā zài mĕi zhĭ shì shùn jiān fú ài qíng zài mĕi zhōng jiū duăn zàn fú]
The phrase means that even the most beautiful fireworks last only a moment and similarly, love, no matter how beautiful it is, eventually becomes fleeting. It symbolizes an acceptance of transience or impermanence in life’s beauty and romance, showing a deep yet sorrowful realization towards such fleeting happiness.
