上课的铃声比忐忑还更忐忑
[shàng kè de líng shēng bĭ tăn tè hái gèng tăn tè]
'The School Bell Is Even More Anxious Than Trepidation' is a creative expression showing nervousness. It compares the uneasiness during classes (especially waiting before class) to anxiety - saying the former even surpasses the latter. This can express stress before important classes or events happening at school.
