The bookshelf Zheng Heming pointed to contained information not on a few children with cavities in their deciduous teeth as he said, but on hundreds of them. The photos were collected from the time when the child's teeth were changing when the child was five or six years old to when the child was about ten years old.
Basically, I take one photo every half a year. In the past five years, I have accumulated a lot of photos.
"These photos were collected for me by my friends from all over the country. Nowadays, when people talk about health, there are not many children with caries. Over the years, I have only collected this little material with the help of my friends."
This is just like making aging software. In addition to writing programs, the most important thing is to collect more people's faces. Only with a larger base will the software's algorithm be more perfect.
Xu Zheng turned around and said, "Teacher Zheng, although these materials are small, they are available in most areas of the country. Even if they are not representative, they can give me a direction. It is very good."
To be honest, Xu Zheng envied Zheng Heming very much. He couldn't do this just because his friends from all over the country continued to provide him with materials for free for five years. He was not a social worker. Apart from his classmates, he had no friends in college. , I have very few friends from other departments.
Now that he is working, he rarely communicates with his classmates, and in WeChat groups, he rarely shows his face to speak, especially after he was transferred to the city's criminal police detachment.
Of course, this was because he did not take the postgraduate entrance examination after graduation, and was different from the direction chosen by most of his classmates. Among the 42 people in his class, he was the only one who chose to work as a policeman at the police station.
Seeing Xu Zheng deep in thought, Zheng Heming smiled, pointed to other bookshelves to introduce him and continued: "In addition to these, there are also other factors on other bookshelves, such as regional factors, serious illness, disfigurement, snoring and other conditions. .
It’s just like dental caries, the material collection is relatively small. "
"This is still less. It is already more than I imagined. I only realized this problem today, but you started researching this topic five or six years ago." Xu Zheng said sincerely with admiration on his face.
Zheng Heming waved his hand, "What's the use of doing research early? There are still no good results after so many years. However, if you join me in this project this time, I think it is very promising."
Xu Zheng didn't want to wear a high hat, and didn't want to dampen the old man's enthusiasm, so he could only use dragging words, "Teacher Zheng, I don't have much time right now. I'm getting married in two days. When I come back from my wedding vacation, let's How about that?”
"Haha, look at me, I have forgotten that you are getting married soon. Don't be in a hurry, don't be in a hurry. It won't be too late to wait until you go to work after your wedding leave." Zheng Heming forced a smile. No matter how anxious he is to get married, he can't rush it.
Qi Guangyuan, who was standing next to him, looked at the teacher and clapped his hands and laughed, "You don't know, right? Xu Zheng will be transferred to the provincial fugitive recovery office next month. From now on, his office will also be in the provincial department. It will be very convenient for you to find him if you have anything. .”
"Provincial Office of Pursuit of Escapers?" A strange look appeared on Zheng Heming's face, "I often cooperate with them in this department. So, Xiao Xu, I have an unkind request. I hope you can consider it."
Xu Zheng looked at Zheng Heming's face becoming serious, and felt a little nervous. This old man would not let him do the work of criminal investigation technology. Although technical investigation engineers and even senior engineers have very high honors and treatment in the police force, there is no criminal investigation line. The work on it is interesting.
Besides, he already has advanced simulation portrait technology. Even if he works with Zheng Heming, it will be very difficult to upgrade his simulation portrait technology to the master level. He does not lack knowledge and talent now, but only lacks experience. Whether he can do the work of simulation portrait or not, He will eventually become a master.
"Xiao Xu, this is what I think. In my current portrait processing studio, I usually provide technical support for portrait processing to the Provincial Department's Fugitive Pursuit Office, Anti-Human Trafficking Office, Criminal Investigation Corps and other departments.
Aren't you going to go to the provincial fugitive investigation office now?
Can you also take on my job at the same time? I will propose to my superiors that the administrative and salary benefits will be the same as those of engineers. What do you think? "
It is very common in the system to hold a formal job concurrently. Many leaders have a series of professional titles. It is perfectly fine for Xu Zheng to work in the Fugitive Pursuit Office and concurrently work in Zheng Heming's studio.
In this case, he stopped being pretentious and said, "Yes, Teacher Zheng, but there is one thing. You also know that the work of the Fugitive Pursuit Office sometimes requires business trips. I can't say the working hours."
Zheng Heming smiled and said, "These are all trivial matters. We work at home or in the office, or on a business trip. As long as we have a pen and paper, we can work anywhere, right?"
"That's true. It's up to Teacher Zheng to worry about the part-time job. If you need me to cooperate, just inform me directly."
After the two discussed the details of the work, they were ready to start today's official task. Zheng Heming collected materials from no less than a thousand children, of whom the majority were boys and only one-fifth were girls. This was because most of the abducted children were boys. reason.
Xu Zheng first chose materials related to dental caries. There were more than 130 photos of children growing up in this category, among which there were only more than 20 girls. He thought for a while and decided to study the situation of girls first.
According to science, dental caries in deciduous teeth will cause the mesio-distal diameter of the teeth to become smaller or even fall off prematurely. This will force the rear teeth to squeeze forward, causing the newly erupted permanent teeth to have insufficient growth space and cannot erupt in their normal position. , further causing malocclusion.
If this happens for a long time, it will cause the child's bilateral facial development to be asymmetrical, affecting the bite and facial beauty.
Common dental crowding, protruding teeth, and buck teeth are also caused by this.
In addition, it will also affect the size of the face. Generally speaking, although most caries in deciduous teeth will affect the area below the nose, the face is a whole. Over time, the entire face will slowly change.
This is what we usually say, this child is crooked.
Xu Zheng lost track of time as soon as he was working. Every time he saw a picture of a little girl, he used a pencil to draw a picture of the little girl without cavities in her deciduous teeth for each year according to her age. Finally, compare it with her real appearance.
This approach of only considering caries in deciduous teeth is indeed not comprehensive, but it can only be done this way at the moment.
After studying more than 20 photos of little girls, he spent an afternoon looking at photos of little boys. After reading them, he did gain something, but not much.
Maybe there wasn't enough material, or maybe there were too many factors that affected the child's appearance. Later, he took out the photo of Jiang Lanxin's ex-husband and wanted to draw a sketch of their daughter Yan Mo when she was twelve years old, but he felt unable to start.
Confused, confused, and clueless, at this moment, Xu Zheng felt like his head was going to explode.
"How about we come here today? How about we wait until you get married and go to work to discuss the rest?" Of course Zheng Heming couldn't always accompany Xu Zheng here to read the information. He had already studied this information many times.
Xu Zheng rubbed his face vigorously with his hands, stood up, moved around, and looked at the studio, "Teacher Zheng, I want to strike while the iron is hot. I'm officially on wedding leave tomorrow. I want to take an overtime class with you tonight. How about that?" "
Seeing Zheng Heming's hesitation, Xu Zheng immediately said: "Don't worry, my young body can handle it. By the way, I will call Lao Qi back again and ask him to accompany me. Are you relieved now?"
"Haha, I'm not worried about the safety of the studio. It's just that if you stay up late like this, it will damage your body..." Zheng Heming looked like he was experienced and explained to Xu Zheng the disadvantages of staying up late for at least five minutes.
It made Xu Zheng want to pass on the six-character mantra breathing method given by the system to him. He thought, if he didn't have this foundation, who could stay up late for a week.
After getting off work in the afternoon, Xu Zheng and Qi Guangyuan went to the provincial canteen for dinner. The guest was Bi Shangxue from the Provincial Anti-Human Trafficking Office. When Xu Zheng called him, he happened to be there. No, the three of them went straight to the canteen.
It is said to be a small canteen, which is no worse than the cafeteria outside. It is worthy of being a provincial department. The food here is much better than that of the city bureau. Xu Zheng was really hungry. He ate two bowls of rice before getting down to business. He first put himself and Qi Guangyuan briefly told Bi Shangxue what he wanted to do.
Then he said: "I am going to work overtime tonight to research this topic, but currently I only have information on two abducted children. Your provincial anti-trafficking office must have a lot of children that have not been found yet. Can you tell these children when they were young? Send me a copy of your photos and basic information.
I am going to try to draw what they will look like when they grow up. If I succeed, it means that this topic is very necessary for research. "
Bi Shangxue was drinking old duck soup. When he heard Xu Zheng describe the topic just now, he felt that it was unreliable, because he knew about the topic Zheng Heming was studying as soon as he entered the Provincial Anti-Human Trafficking Office.
After all, the Provincial Anti-Human Trafficking Office wanted to take photos of children's growth, and these had to be handed over to Zheng Heming's studio. He also knew that Zheng Heming had been researching for five years with no results.
"Zheng'er, are you too anxious? Let's not talk about how many years Master Zheng has been studying this topic. Let's talk about Dean Lin from Lu Province. After retirement, he made a big ambition to draw 100 abducted children, but he He has been retired for many years now, and the police have only found a dozen children based on the simulated portraits he drew."
Regarding what Bi Shangxue said, Xu Zheng also knew that simulated portraits would be helpful for the police to find missing children, but they were not very helpful. Compared with DNA testing, they were still slightly inferior.
But now, since Xu Zheng has chosen to study this topic, the difficulties Bi Shangxue said cannot scare him away.
Seeing Xu Zheng's expression, Bi Shangxue sighed inwardly. This kid was still so stubborn, but he also thought about the case where Song Meimei's son was lost last year. If it weren't for Xu Zheng's stubbornness, how could he have found it?
"Okay, since you want to try it, I'll go back to the office after dinner, apply to Director Ye, and send it to you."
Xu Zheng patted Bi Shangxue on the shoulder, "Brother Bi, believe it or not, when you go back to sleep and come to work tomorrow morning, I will directly give you some credit for your work. Do you want it or not?"
