Root Role Change

It's not that only computer systems can circumvent the wall, life is the same. Different changes have created different lives, some are good and some are bad. So which path is yours and how you choose is hard to say. Now I want to introduce you to everyone and give you a new friend. Although the label here is urban, in fact, at present, I don't think there is a better label to summarize what I write, because in fact, it is a fictional book that travels back and forth through thoughts. I hope everyone likes it.
