学渣的世界你们不懂
[xué zhā de shì jiè nĭ men bù dŏng]
'You Don't Understand the World of Academic Failures.' A lighthearted expression showing self-mockery, humorously pointing out struggles in academic pursuits, and implying that the struggles and perspectives of poor learners (sometimes referred affectionately as '学术废柴' (xué shù fèi chái) meaning 'academic waster')) can't really be understood by others.
