The Eight Generals of the Thousand Gates: 108 Strategies

In this world, legitimate methods and fields of knowledge emerge one after another, while scams evolve with the times, taking on endless new forms. From ancient times to the present, scams have spread like the waters of the Yangtze and Yellow Rivers, flowing without end and never disappearing. Their harm is both profound and widespread: they can leave individuals penniless and shatter society's trust.

Yet everything in the world has its opposite. Just as a spear must have a shield, if scams exist, ways to expose them must exist as well. There is now a wise man whom everyone respectfully calls Mr. Zheng. Using extraordinary intelligence and an encyclopedic range of knowledge, he has collected and compiled scams from past and present into a book titled "The 108 Schemes of the Eight Roles of the Thousand Gates". This is truly a great blessing for the world. If these techniques are not used for good, they will surely become a grave menace. Mr. Zheng understands this deeply, so he exposes each scheme one by one, helping readers not only recognize what a scam looks like, but also understand why it works, so they can avoid being fooled.
