The greatest salesman in the world. Does the name of this book look amazing? It seems that it has nothing to do with a person who has studied Chinese. In fact, my fate with it is also amazing. I still remember that during the winter vacation of the third year of college, several primary school students gathered in a small area. I was sitting on a stool at my classmate's house and accidentally picked up a book next to me to read. Well, that's it. I don't know why, but the name of such a book appeals to me. I flipped through it casually and was immediately attracted, so I almost finished flipping through the book on the afternoon of the class reunion. I don't know what the students are talking about. Later, I never thought that it was such a small book that I picked up inadvertently, and it was such a book that was completely out of touch with my major, which changed my future life track.
