帅哥再帅终究无奈美女再美终究枯萎
[shuài gē zài shuài zhōng jiū wú nài mĕi nǚ zài mĕi zhōng jiū kū wĕi]
This phrase conveys disillusionment regarding appearances by stating that no matter how attractive someone may appear, ultimately everyone will experience disappointment or decay ('Handsome men can't remain charming forever, beauties eventually fade.')
