This is an article to change the mood. The incest Quartet is so exhausting that I have been working hard, even painful, in the process of writing. I can’t write when I am still. Sometimes I can’t write a word when I look at the computer screen all night. So I will write this kind of relaxed article when I’m not in good condition, and it has become an article unconsciously. It’s just that it’s scattered, and there’s no main plot to speak of. It’s more like prose or essay. You can enjoy it. To tell you the truth, I don’t know how this kind of writing is. If you think it’s not too bad, please support it. Of course, I want to set up a world outlook. Maybe I can write a series of essays in this context. For example, “nurse’s Day”, “teacher’s Day” and so on. Because of the incest tetralogy, I want to explore some profound themes. It must be a long work, and there must be a change of mood.
