Demining: This article is based on the author and his friends, so the camera is on the author's side, but the emotional line is pure love, emmm, because the emotional line is the product of my YY. In addition, this article will take a long time to write. I started this article first because I promised that this is my first article. I may finish several books before finishing this one. Also, my writing skills are very poor. I write because I want to produce food for myself.
