Aesthetic appreciation is a very diverse thing.
Some people like radishes, some like cabbage; some prefer Impressionism, some like Abstract art, Realism, or Postmodernism.
The above sums up Qin Huai's entire understanding of aesthetics before he read the book given to him by Master Zhou.
After reading one of the books, Qin Huai's perspective changed. He realized he didn't really understand what beauty was and could no longer define aesthetic appreciation. Now, he felt like he knew nothing at all.
In a sense, Master Zhou had utterly disoriented him. Although he hadn't forgotten everything from before, he was completely confused, and confusion is a form of forgetting.
Qin Huai even started to understand Shi Dadan; he now had a sort of allergy to books, wanting to sleep whenever he saw words.
