While my parents were waiting for the door to open, Luo Luo’s attention was still on her “magic snapping fingers”!

Why didn't there be any sound? Why didn't you become magic like your father?

I saw the little girl's two short and thin little fingers gestured the shape of the "7" after snapping her fingers. She looked at her fingers and was still very focused, but her little mouth was slightly pouting. Her cute little look was very cute!

Now, when the little girl heard the creaking sound of the iron gate, she woke up. She raised her head in a daze, but found that there was a national face in front of her, but she was very thin and her sideburns were looking at her!

The bright eyes were full of momentum, and Luo Luo was so scared that he retracted his little hand. He hugged his father's neck nervously, leaving only a pair of black and white big eyes, crystal clear and clear eyes, and the energetic old man, looked at each other timidly.

"The occupational disease has happened again!" Old Master Dai Guoxun saw the scared look in front of him, and couldn't help but blame himself secretly, and quickly withdrew his sharp eyes.

The old man was surprised that Xia Yu came over just now. Not only did he bring his boyfriend, but he also brought a child. His brain, which was used to reasoning, quickly calculated that something was wrong in time...

Dai Guoxun still had a deep impression of Xia Yu, the student!

It’s not because he has the talent to recognize people without any memory, but because the ratio of men and women in the police academy is as disparate as that of engineering colleges, and Xia Yu is one of the few top students, and she is as good as men. Moreover, she made many achievements not long after she entered society. The old man naturally remembered this proud student, and he agreed to Xia Yu and her boyfriend’s request to visit him.

But after Mr. Dai opened the door, he saw not the two people he expected!

There is a little cute one among Xia Yu and Yang Yan!

The little girl is still very likable. Under the lights in the corridor, the old man saw her pink face, her skin was smooth and tender, and her unforgettable watery big eyes!

Mr. Dai has no children and devotes his life to the criminal investigation industry. However, when people enter old age, they will inevitably think of the regret of missing in their lives. Seeing such a cute baby, Mr. Dai will inevitably feel happy.

But occupational diseases still prevail!

The old man looked at Yang Yan and Xia Yu standing close together, like a family, and he couldn't help but burst into a series of reasoning in his mind.

The baby is about two years old, or over one year old, including the ten months of pregnancy... In other words, Xia Yu walked with people outside the school before he graduated, and then got pregnant?

But why does Xia Yu look so slim? He doesn't look like a woman who has given birth to children.

However, the old man is not very sure about this judgment. After all, everyone's physical condition is different. There are also young people who don't like to eat and drink and still have a slim figure after giving birth to children.

The old man's quick-moving brain also thought about another question, why did Xia Yu just call this man his boyfriend? He had already given birth to a child, but he was not married yet?

Young people are really too open now...

The old man finally attributed this problem to the change in the concepts of some young people in society. It was not uncommon for Yangcheng, or Guangdong Province in recent years, and some even caused disputes and murder cases.

Of course, no matter what the young people think, Dai Guoxun did not impose his traditional ideas on others' ideas. Moreover, he vaguely showed a very co-starring feeling when Xia Yu and Yang Yan were not allowed to talk too much.

So, after retracting the look that scared the cute little girl, the old man shook his head slightly, temporarily putting these uncontrollable reasoning thoughts aside, and inviting Yang Yan and Xia Yu in.

"Teacher Dai, Xia Yu said that your family has regulations and I am embarrassed to bring things over." Xia Yu is not good at saying some polite words. After she introduced herself and the old man, Yang Yan exchanged a few greetings with Mr. Dai.

"What's the shame?" Old Master Dai arranged for Yang Yan and Xia Yu to sit down on the wooden sofa in the living room. Yang Yan said while holding Luo Luo. His eyes secretly looked at the surrounding environment.

The house where Mr. Dai lives is an old house allocated a long time ago. It has a relatively long balcony with two bedrooms and one living room. It is not small or big, but at least it is larger than the house where Yang Yan and Xia Yu live now.

But the old man’s house is really too simple!

There is almost no furniture in the living room, a simple wooden sofa, one long and one short, plus a matching wooden coffee table. In addition, there is only an old bookcase near the wall, and there is nothing else, not even a TV!

The bookcase was filled with books and a small black and white photo frame. Yang Yan glanced briefly and did not see clearly the person in the photo frame. But what can be confirmed was that it was a black and white photo, and the photo was a young woman.

It can be seen that this bookcase should be filled with the old man’s spiritual food and his spiritual support...

Although Yang Yan had a little premonition before coming up, he still did not expect that Teacher Dai was still such a thrifty person!

Thinking that he was still struggling on the front line of criminal investigation when he retired, Yang Yan couldn't help but feel a little respectful.

"Teacher Dai, I'll do it!" Xia Yu's voice brought Yang Yan's thoughts back to reality. He saw that Mr. Dai Guoxun was busy pouring water for them.

"You sit down, sit down quickly, come to the teacher, you are the guests!" Dai Guoxun waved his hand with a smile.

Although his temples are gray and thin, his body is still relatively strong. In his every move, there is also the majesty and neatness accumulated by an old criminal policeman over the years.

Whether it is Teacher Dai, Yang Yan or Xia Yu, they are actually not people who like to talk nonsense. They just sat down and exchanged greetings for a few words, and they quickly got to the point.

"Before, Xiaoxia told me, Xiao Yang, what are you doing now to prevent trafficking?" Dai Guoxun sat on the sofa, his waist straight!

Yang Yan felt embarrassed to see this. He quietly straightened his collapsed waist, but what happened to him? After a while, he felt the soreness again and could not hold on, so he could only move his butt secretly and then introduced to Dai Guoxun the "intelligent people-recognition" system he wanted to do.

After listening to Yang Yan's endless introduction patiently, Mr. Dai nodded slightly and said, "Xiao Yang, you have a good idea, but the function of this camera to recognize faces is not a new technology, right? I remember that this project was installed a few years ago, and it was only used for entry and exit monitoring, and it has not yet been popularized in the police field."

Yang Yan is not working behind closed doors. He knows the current development and application of facial recognition technology. After hearing the old man’s problem, he cheered up and told the old man about the special features of his “intelligent human recognition” system and how he wants to apply it in the field of anti-trafficking and seeking relatives.

"At present, the face recognition system is still very simple, it is just a simple coordinate data comparison, and the requirements for cameras and machines are relatively high, so scanning equipment needs to be preinstalled in advance..."

The poor family says
