The citation is very comprehensive. Although the discussion on smuggling is not new, it is worthy of my reading time. Although the angle is not very economical and not very historical, the storytelling needs to be improved, and it feels a bit miscellaneous. But in view of the fact that there are few reference materials on smuggling, this book is already very good. After reading it, I feel that smuggling acts as a lubricant for social life, but from different professional perspectives, there are different opinions on how much lubricant is put on and whether it is harmful. I feel that this book provides an insight into smuggling, but it is also limited to this.
