There is a poem that says: "People in the world need gold to make friends. Without too much gold, friendship cannot be deep. Even if you make a temporary promise, it will eventually be a long journey." It turns out that the ancients have already understood the true meaning of social interaction. For thousands of years, people have never escaped from this unattractive but ubiquitous law. With the law, the so-called circle is formed. The circle is wonderful and ubiquitous, like a black hole in the universe. Nothing can escape its attraction. You will unconsciously feel that if you go in, not even the bones will be left. But then again, there will always be some weird and unusual people who do not follow common sense in ordinary life. He or she always jumps out of circles consciously or unconsciously, performing feats of free falling or spreading wings again and again. In this book, we will talk about this. "Circle", let's take a look at the life history of our protagonist Qianjun. His experiences in various circles after graduation are rich and colorful. If you are also in a certain circle in this book, I hope that after reading this book, you will have a long sigh and a hint of enlightenment, which is enough.
