This article is actually a collection; I have read it a lot; I am always eager to try it, but unfortunately I am not long-term, so I cannot write so many miscellaneous long articles, and I have a lot of thoughts in my mind. . . Well, if I want to say anything, just come and watch, I'm very happy; if you don't like it, don't complain, there is a cross on the upper right, please leave quietly. . . I don't know what it will be like. . . .
