小明不死数学难亡小红不灭语文难老
[xiăo míng bù sĭ shù xué nán wáng xiăo hóng bù miè yŭ wén nán lăo]
If Xiao Ming (a typical boy's name) doesn't study hard, he'll struggle with math; if Xiao Hong (a typical girl's name) neglects language studies, she'll suffer from difficulties in language arts. A humorous and somewhat exaggerated statement referring to academic challenges faced by students.
