致我们终将逝去的青春致我们终将腐朽的青春
[zhì wŏ men zhōng jiāng shì qù de qīng chūn zhì wŏ men zhōng jiāng fŭ xiŭ de qīng chūn]
In Dedication to Our Youth That Is Bound To Fade Away and Eventually Decay - This is poetic recognition that all periods of youth come with an expiry, acknowledging how time ages even what was once fresh and vital.
