This is my first article. This is also my "eldest son". I had never thought about writing a novel before, but I suddenly wanted to write down what I usually think about. I never thought how many people would read it, so I didn't care how many people would read my article. I am just very grateful to the little angels who have read my article, whether it is the little angel who has been collecting it in the corner of the book list, or the little angel who is silently pursuing it, Qingmei is here to thank you for coming and reading it. Thank you for not complaining about my immature writing style, tacky ideas and unloving attitude. Now due to academic reasons, I really have to stop reading. I won't say anything nice, lyrical or pretentious, I just want to tell you that this article is not over yet. My green plum will come back.
