穿着校服进酒吧背着书包闯天下
[chuān zhe xiào fú jìn jiŭ ba bèi zhe shū bāo chuăng tiān xià]
'In school uniform visiting pubs; With backpack embarking into world with confidence.' Contrasts youthful innocence (wearing uniforms) with mature behaviors (going into bars), symbolizing the adventurous spirit and boldness youth might exhibit when challenging boundaries and venturing out into broader life experiences.
