In advance, this article was not written by me, but it was really written by my good friend. Because he had not written an article, would not publish it, and could not climb over the wall to the courtyard, so he specially authorized me to publish it in the courtyard. I don’t know if this is in line with the rules of siheyuan. If not, I hope Xiangda and other management can correct it. This article is not a novel, but according to the oral statement of the party concerned, it is recorded by the bright moon dampness, without any added false elements. Dashi hopes to give different feelings to the majority of hospital friends.
