凉城往事少年依然孤身独处
[liáng chéng wăng shì shăo nián yī rán gū shēn dú chŭ]
This translates to 'The Young Boy from Liang City is Still Alone', referring to someone recalling old memories in solitude. It suggests that even after a long time and much has changed (like Liang city, which could mean where they're originally from), the loneliness remains with this person, highlighting an enduring state of solitude.
