薄凉少年葬空城
[bó liáng shăo nián zàng kōng chéng]
A poetic expression where 'a cold-hearted (or world-weary) youth entombs himself in an empty city'. This describes someone young yet emotionally aloof or indifferent, almost as if their surroundings lack life and meaning to them, hence 'an empty city'. It carries a sense of loneliness and detachment.
