In the classic mystery novel, the great detectives said: "Every small result must have a specific cause, and that is the truth." In the process of real case investigation, experienced investigators said: "There are thousands of possible reasons for every tiny result, so don't take assumptions for granted. The truth needs to be stably supported by multi-angle evidence before it can finally be revealed. .” I prefer the latter view. Real case investigation is multi-professional and cross-departmental collaborative work. Facing the same case, it uses various methods such as on-site investigation, trace inspection, document inspection, audio-visual data identification, forensic medicine and physical and chemical analysis to find subtle clues from different angles. clues, so as to establish a stable and reliable evidence support, and finally come to the truth.Forensic medicine is the most special of these professions, because the object of their examination is the human body.

Whether it is testing the injuries of living bodies or the characteristics of corpses, it is destined that the psychological endurance of forensic doctors is far beyond that of ordinary people.Through professional and scientific methods, they observe, analyze and identify the bone, skin, muscle, fat, internal organs, blood and nervous system of the test object one by one, so as to infer the time of casualty, the tool of injury, the force and angle of the blow, and even The psychological state and special psychological characteristics of the suspect at the time of committing the crime.Whether it is a living wound or a corpse, ordinary people have a strong fear stimulus. This is a normal physiological and psychological reaction of creatures when they observe their own kind being hurt.But after long-term scientific and professional training, for forensic doctors, these have long been left behind inconspicuous little stones.They have only one thing in mind - the truth.

Teacher Qin Ming is an outstanding but ordinary member of many forensic doctors fighting on the front line.When his book (formerly known as "Ghost Hand and Buddha Heart") was serialized on the Internet, I often couldn't stop reading it, and couldn't help but urge to update it.These stories, born out of real cases, cleverly incorporate a lot of professional knowledge and investigative wisdom. The wonderful plots exude an irrepressible uprightness, as well as the optimism and humor of a group of forensic doctors.I learned a lot of useful things from the story, which provided excellent reference and guidance for my research work on the psychological micro-reactions of criminal suspects, and also laid a solid foundation for me to cooperate with more departments of different professions in the public security department. good foundation.

Quoting a passage from Mr. Qin Ming: "At the hottest time of the year, the temperature exceeds the normal temperature of the human body, which also provides good environmental conditions for the growth and reproduction of spoilage bacteria. When many civil servants hide in air-conditioned rooms for mental work At that time, the forensic doctors were still under the scorching sun, salvaging and examining corpses of different shapes in the mountains and rivers. It is no exaggeration to say that the corpses are decomposed every day. From green to the appearance of a corrupt vein network, to the blackening and swelling of the corpse, and even the appearance of a giant, which is the most headache for the forensic doctor. No matter what the corpse becomes, the forensic doctor cannot ignore it, nor can he fool the mission." We It can be seen that in every major and important case involving injury and death, there is a lot of hard work by the forensic colleagues.
