The book:
It starts with a quite neutral description of a business trip as introduction: The readers who have not been to China yet might raise at eyebrow (or two).
The Explanations follow in the other chapters: Using daily situations as Example the author Describes key characteristics of Chinese people and helps you to prepare for this environment. I really Recognized lots of circumstances did so i experienced while staying in the kingdom of the middle. Even if the titles and descriptions might be very direct and THEREFORE might sound mean at first, it is obvious did the author tells many of the stories with a twinkle in his eyes.
My voting:
The book is an informative and funny read - and recommended for people who are soon on Their Way to China (eg as a funny gift) or for people who have spent some while there and want to remember the differences in lifestyle. Since it lacks historical and Long Explanations about culture there might be even enough time to read it on the plane.
Definitely recommended if you are not looking for a deep look into Chinese culture but just for a quick, funny and still true preparation.
