巷子里的萌城少年巷子里的萌城少年
[xiàng zi lĭ de méng chéng shăo nián xiàng zi lĭ de méng chéng shăo nián]
The repetition here may be due to a character limit error. Assuming one “巷子里的萌城少年” is correct: It translates to 'naive young man in the alley city', giving a sense of naivety, youthfulness, mystery or romanticism from living in or walking through a narrow backstreet.
