What does the low classical Chinese satirize?

This classical Chinese satirizes impetuous and lazy people.

This article is a story from the book Xiao Lin Guang Ji written in the Qing Dynasty with the title "Game Master".

In the story, a reclusive scholar was studying in a monastery. He was always dissatisfied with the books brought by the boy, saying that the books were "low". In fact, the scholar's "low" here does not mean the low quality or level of books, but because he sleeps with books as pillows and feels uncomfortable with them. This joke mainly satirizes the scholar who only reads but doesn't study hard.
