Psychological manipulators have existed since ancient times, but these dangerous people are still little known: the general public who accompany psychological manipulators every day know little about them; Institutions filled with all kinds of psychological manipulators know little about them, even the judiciary. Doctors and therapists in treatment facilities know little about them, even though victims of psychological manipulation have crowded their workshops. The victims of mental manipulators know very little about them, and usually wake up too late when the trap comes their way.

However, the image of the mental manipulators is a standard for insidiousness, and the description of the victim is always the same. The author witnessed everything happened inside the family and decided to offer the information accumulated after 20 years' practice to everyone. To better understand the separation from mind manipulators, the author provides necessary clues to enable the victim to escape from the labyrinth of mind and law without being destroyed by the hypocritical mind manipulators. Let the legal and social institutions know what is behind the psychological manipulators. To give a wake-up call to society to be wary of being manipulated and indoctrinated by a few hateful and destructive people. The author also gives specific examples and cases in the book.
