Shen Yu: I hope you are safe every year
Lu Qichuan: I hope you will be happy every year
Short story, last year, this article is a short article written for myself to satisfy the author's own little regret. Everything in the article that I feel is unreasonable is reasonable, there are some weird points, and there are bugs. I wrote the article to make myself happy. If you don't like to read it, you can choose not to read it.
Intention: an article written for myself
