祢是我此生最美的风景妳是我此世最靓的芳华
[mí shì wŏ cĭ shēng zuì mĕi de fēng jĭng năi shì wŏ cĭ shì zuì jìng de fāng huá]
'You are the most beautiful scenery of my life and the brightest youth of my lifetime' expresses deep admiration, suggesting the person has made a lasting and profound impression on the user. 'Nǐ' and 'Nǐ' in this sentence are both used for the second-person pronoun but differ slightly in context and classical use which could indicate affection, poetry style, or intimacy.
