The Spiritual Sustenance of an Empty-nest Bookworm

I have lived on these books for more than 10 years of my 20-year life, and I have read many books. However, I personally feel that these works can be read once, and can be savored in leisure time. Many of them need to be read calmly. In this impetuous era, take some time to calm yourself down. PS: I have a question, what do you think is a classic? I think a classic is that 10 years later, even if I forget the name of the novel, I can still remember some of the plots in it, and I will have emotional fluctuations because of these plots.
