I'm sorry, everyone, I wanted to start writing a book after a day or two off after returning from my hometown, but I overestimated my concentration. When I relax from the tense and orderly environment, when I face the web page again, I really can't get the energy to write, and I feel a sense of resistance every time. So it dragged on and on, and it took a week. I also understand that I can't be lazy.

Therefore, Bao Tong's postscript will be written as soon as possible, and the new book will be uploaded as soon as possible. Also, the new book is still urban. (To be continued.) )
