却道黄昏时
[què dào huáng hūn shí]
A poetic phrase suggesting that something can only be talked about or realized at dusk (metaphorically speaking), implying that it's too late or it's already the sunset phase of something. 'Dusk' has rich symbolic meaning; it represents the transition from day to night, possibly signifying twilight of life, love coming to an end, or certain bittersweet situations at this point in time.
