First draw a criminal suspect according to the description in other people's language.
In ancient times, there was actually a portrait painter. It was the people above the yamen at that time. They drew the suspect according to other people's statements. At that time, the skills of portraits were certainly not as exquisite as they are now. And JC-T, the role he plays in TV series, is actually a portraitist, but the portraitist's skills are superb. Even if he has never met anyone, he can draw a criminal suspect according to the description of others, which is really a painting with a pen as a gun.
Second, it was very simple at first, and then it was considered comprehensively.
For portrait artists, what they see most should be objects, whether human bones or other things, they can explore the clues they need. I used to think that portraits can only be restored by computer, but later I found that sketches can also draw the original appearance and suspects. In this play, the portraitist also showed his ability to lead the audience deeper into the plot. You know, painting is a very hard work, and you need to position yourself. For those professional portrait artists, there are many things they need to consider, and some things have become instinct in their bodies. As long as you say it, I can describe it to him.
In the process of solving crimes, JC-T plays an increasingly important role. At first, he was confident, but later he found that some people would take advantage of various loopholes in their lives to take advantage of them. So he began to slowly change his mind and provide more help and support for the police.
