深巷旧年少女依旧独守孤城凉城往事少年依然孤身独处
[shēn xiàng jiù nián shăo nǚ yī jiù dú shŏu gū chéng liáng chéng wăng shì shăo nián yī rán gū shēn dú chŭ]
Translated as: In narrow lanes from the past years, that same girl stands alone in her empty city, while boys in the old towns remain unmarried too. It implies reminiscing over old days, loneliness and staying unattached.
