学霸学霸不学也罢学渣学渣不学是渣
[xué bà xué bà bù xué yĕ bà xué zhā xué zhā bù xué shì zhā]
A somewhat self-deprecating phrase which can be translated to 'top student doesn’t mind not studying sometimes; poor student really shouldn’t skip study.' It humorously describes academic performance and attitudes towards learning.
