试卷是一张微凉的情书
[shì juăn shì yī zhāng wēi liáng de qíng shū]
'The Test Paper Is A Cool Love Letter' gives a romantic interpretation to a test sheet. This suggests exams can feel personally challenging much like expressing one’s affections; however, here they carry less intensity and thus described as cool. It reflects treating challenges with grace as a way of learning.
