Ancient prose: If your level of ancient prose is acceptable, it is of great benefit to read more ancient prose. Read more ancient prose, and you won't be afraid. You will feel that this is a kind of enjoyment. Needless to say, the four books and five classics are especially recommended. However, there are many similar stories. Pick a few famous ones and have a look. Han Yu's ancient prose is a classic among the eight masters. It's good to read Mr. Changli's anthology.
Foreign literature: I don't know if you have read the book "Golden Rose", which is very profound and warm.
Never interested. However, a guy in our dormitory read the notes of grave robbery and thought it was the best novel he had ever read. This guy doesn't usually praise books easily. I think there should be something to read. Interested parties may wish to have a look.
