The title of this story is of course related to the content, but it is also for fun—these four characters lined up on the cover of the book will definitely have a strange visual effect, which is quite interesting. It suddenly occurred to me: Actually, it is very "wasteful". It can be separated into the titles of two books, one is called "Retreat" and the other is called "Switch", wouldn't it be wonderful! In this story, there are some new discoveries. For example, the development of human brain function is the evolution process of human beings. Such a mess. The last time I sent an open letter to children in mainland China who uploaded all my works online, the children doubted whether it was true or not, and it should be clear by now.Recently, I learned about the piracy of my works in mainland China from their Internet, and I can tell you that all published in the name of publishing houses in mainland China are pirated copies. For this kind of blatant, widespread, and long-term infringement of intellectual property rights I am not surprised that it happened in mainland China, because obviously the level of brain function development is still shallow, and it has not yet reached the level of knowing to respect the intellectual property rights of others, and there is a considerable distance from people in other parts of the world.

With such a distance, how can we integrate into a civilized society?
