The author takes notes on the evolution of his literary ideas and thoughts, which is a kind of "thinking draft of talking to himself".

There are many ways to do it, such as reading abstracts, reading notes, writing letters, speaking, speaking and writing. Reading notes is for your own understanding; Talking, discussing and writing letters are to make a friend understand; Making speeches and publishing articles is for a group of people to understand. These are all "fun" and they all help you understand. Because the author believes that reading notes have this function, he often takes reading notes as the draft of his own thoughts. Such as the author's views on world concern, non-war concern, non-resistance and literary revolution.
