The first classic work of forensic medicine in China was written by Song Ci. Song Ci, a loyal criminal prosecutor who is good at finding a breakthrough in a case from clues, was vividly portrayed in the Song Dynasty. He treated every corpse that could find out the murderer seriously and solved many difficult cases. He also wrote a book "A Record of Wrongful Cases", which is regarded as the originator of forensic medicine. He said this in "Revenge for Revenge", insisting on hearing a case many times and attaching importance to on-site inspection at the same time.

The book is divided into four volumes, which are discussed from physiology, pharmacology, diagnosis, treatment, prevention, first aid and inspection. Many contents are still in use today and have made great contributions to the cause of modern forensic medicine. For example, when a fracture occurs, splint is used to fix the fracture site, and skin is peeled alive to wrap the wound, which is elastic. These are all based on the on-site experience, and at the same time, the modern artificial respiration is introduced, which was initiated by Song Ci in the Southern Song Dynasty.

In toxicology, he thinks: "Those who leak fire and stink in the pit have been fumigated, but their bodies are soft and intact ..." This description of poison gas poisoning is very close to the modern death caused by carbon monoxide gas leakage.

There are some inspection methods in the Collection of Unfair Memories, which belong to the inspection category, but they are in line with modern science and amazing. For example, if you use an umbrella dipped in bright oil to examine the bones, it is an example: "After the autopsy, the bones were damaged, but the traces were gone. If you spill the corpse with bad (distiller's grains) and vinegar, you can see the place you want to see in the open air with new oil silk or bright oil umbrella, and look through the umbrella every day, and the traces will appear immediately. If it rains, take hot charcoal as shade. This good law is also. " Cover the bone with a red oil umbrella. If there are collision marks on the bone, there are red lines and slight shadows. At the fracture site, there is blood halo color at both ends of the extension; Looking at the sun with traces of bones, Hong Huo was clearly beaten before he died. If there is no shadow of blood on the bone, even if it is broken, it is also a trace after death.

These seemingly mysterious inspection methods are actually not mysterious in modern times, that is, they use optical principles. However, in ancient times, when productivity and technology were underdeveloped, the advanced experience of Song Ci was valuable.

Song ci was serious and cautious when he was a prosecutor. In the career of more than 20 years, Song Ci was honest and clean, lived a simple life, had no other hobbies all his life, and was more modest and prudent in his later years, cherishing talents. Although he is a junior, he will be promoted and recommended as soon as he has the ability. Because of his prudence and seriousness, many unjust cases have been cleared in his hands, saying that he is the originator of forensic medicine. There is nothing wrong with it. In the long history of China, Song Ci is a brilliant star, and he is destined to go down in history.
