Some memories cannot be forgotten, but they will be blurred; some knowledge can be remembered, but they will be confused.
Teachers often say, "A good memory is worse than a bad writing." This makes sense.
(All chapters are independent and are essays. In fact, I just want to read over what I have written before. There is a lot of childish and messy content. After thinking about it again and again, I decided not to write a word. It is not because the content is good, but because I want the feeling.)
