Halfway through writing, I cut out and read the comments, and many readers and friends said that this book is off topic (I originally set it to be an urban game article, and the proportion of cities is more).

So now I'm going to do a content survey (I won't do a questionnaire, so let's move to the top of the book review below), I'll give you a few options, you can choose them, I'll look at the results, and then I'll start adjusting the outline. (After all, it's best for everyone to watch it.) ）

Please join us, and thank you!
