The middle-aged woman seemed happy to chat with Gu Chen, perhaps because she didn't have many friends here, so when she saw a handsome young man like Gu Chen, she was happy to chat with him.
"Xiao Wan." At this time, another middle-aged woman came back from the yard carrying a vegetable basket, followed by a six or seven-year-old boy.
He also saw her chatting with Gu Chen, so the middle-aged woman carrying a vegetable basket couldn't help but ask: "Is this your relative? Or a friend?"
"Haha, how can they be my relatives?" The woman named Xiao Wan smiled, looked at Gu Chen and joked: "I wish I had such handsome relatives. These are tourists who come to stay here. I just bought
The fruits that came were scattered, so he helped me pick them up, and we just chatted for a while."
"I'm telling you." The middle-aged woman carrying the vegetable basket also looked at Gu Chen up and down and then said with a smile: "Why have I never seen you here before? You are a tourist, but we don't have tourists here.
If it’s too much, the rent will go up.”
"Haha, look what you said." Gu Chen responded with a smile.
At this time, the six or seven-year-old boy simply helped his mother take down the vegetable basket, walked to Room No. 10 next to Gu Chenfeng's garage, opened the door and walked in.
"You live next door to me?" Gu Chen said.
The middle-aged woman who was carrying the vegetable basket also smiled and said: "Yes, Wan Xin and I are fellow villagers. We both work here. I live in Room 10, she lives in Room 9, and there are a few others here.
The windmill house is also from our hometown."
"Oh." Gu Chen just asked casually, but he didn't expect this elder sister to be so enthusiastic and wanted to chat with Gu Chen for a long time.
Seeing that Gu Chen's response was not very enthusiastic, the woman wiped her hands and took the initiative to greet Gu Chen: "My name is Su Jing, what's the name of this handsome guy?"
"Gu Chen." Gu Chen extended his hand to deal with it.
"Then welcome little brother Gu Chen to come to Dahe Town for a trip. I will be selling tickets at the cinema in the town. Come and have fun when you have time."
"good."
After the two briefly joked with each other, the woman named Su Jing also left, leaving only Wan Xin, the single mother from before, still standing there.
Seeing Gu Chen's embarrassment, Wan Xin smiled and said, "This is my fellow villager. He is a very enthusiastic person. He lives next door to my house and we have a good relationship with him. I usually want to come over and chat with him when I see a handsome guy."
"Haha." In addition to being embarrassed, Gu Chen was a person who rarely spoke. He also saw that the other party was too enthusiastic, so he didn't know what to say.
In fact, this has much to do with Gu Chen's work habits.
When handling cases, Gu Chen can talk endlessly about criminals based on clues, cooperate closely with colleagues, and talk a lot in a day.
But when the work is over, Gu Chen will instantly become a quiet person. If it is not necessary, he will not even say a word.
Only Lu Weiwei often talks to herself, otherwise her attribute of being a talkative brother will become more and more serious.
Looking at the vegetables in his hand, Wan Xin said: "Look at my brain, I even forget the time when I see a handsome guy. I have to go back to cook. Do you want Gu Chen to come over for dinner?"
"No need." Gu Chen refused with a smile: "My family went to buy it."
"Oh." Hearing that Gu Chen came here with his family, Wan Xin smiled and said, "Then I won't disturb you. I'll leave first. Bye."
"Bye-Bye."
After saying goodbye to Wan Xin, Gu Chen took a walk on the lawn in the yard. When he saw his father Gu Baichuan driving back with his mother Xiao Xiaofang, he took the key and opened the door.
In the evening, the family watched TV with great interest and ate delicious food in the windmill room, feeling that this is how a vacation should be.
Xiao Xiaofang looked at Gu Chen lying on his side on the sofa and couldn't help but ask: "Son, is it too late to go to work tomorrow morning?"
"There's enough time." Gu Chen didn't move and replied directly: "All the clothes for work are stored in the branch. I will drive directly to the branch tomorrow morning, and you can take a taxi home."
"Yeah, okay." Xiao Xiaofang said.
Gu Baichuan also said: "As a police officer, everything is good, but there are too few vacations, especially for you criminal investigation team."
"We don't know when the next time our family will travel."
"There will be plenty of opportunities in the future." Gu Chen still looked like a stone Buddha.
At this time, there seemed to be some noise in the yard outside. A group of children were playing on the lawn under the moonlight.
There was even a naughty guy lying on the living room window of No. 11 Windmill House, peeking at Gu Chen's family watching TV.
Unable to bear the noise of the children outside, Gu Baichuan directly closed the curtains, then walked back to the room and said, "I'm too tired from playing today. I'm going to go to bed first, and you guys should go to bed early."
"Know."
"Watch TV and then go to sleep."
Gu Chen and Xiao Xiaofang responded in unison.
…
…
A week after returning to the Furong branch, the work did not seem too cumbersome.
Since all kinds of thieves are rampant at the end of the year and stop after the new year, the work is not considered busy, and there is even some leisure time.
Therefore, the bureau has also adjusted some rest hours, and many evening shifts have been cancelled.
After the Lantern Festival, most people are holding summary meetings and planning work for the new year.
Gu Chen was a little overwhelmed by the reports these days, but colleagues from other places brought a lot of specialties from his hometown, which was the only thing that made everyone happy.
In the office lobby on the first floor, a little girl applied for an ID card for the first time and received it. After looking at the document in her hand, she also said coquettishly to her mother: "Mom, I will also have an ID card from now on."
"Yes, my daughter has grown up, but don't throw this thing away. Be careful to replace it if it's gone. Also, just leave it at home, but don't let bad people use your ID card to do bad things..."
A loving mother can nag her daughter about her teachings for a long time, and the girls are a little impatient. They keep nodding and saying yes, but in fact they are already absent-minded.
I also saw Gu Chen, Lu Weiwei and Officer Wang. The three of them just came down from upstairs. They met several people who came to handle business and were busy explaining their problems to everyone.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! So the girl quickly took her ID card, got rid of her mother's shackles, came to Gu Chen and said: "Comrade police, they all say that our country has a large population.
Then won’t our ID number be enough?”
Gu Chen looked back at her and said with a smile: "Are you here to apply for an ID card?"
"Yes." The girl held it in her hand and showed off: "I just got it today."
Gu Chen nodded slightly and directly took the girl's ID card.
Although the girl's question was a bit childish, Gu Chen still showed his ID card in front of her seriously, pointed to the citizen ID number below and said: "This string of numbers cannot be repeated, and it is also the code for your identity."
When the girl saw Gu Chen responding to her, she immediately smiled and said, "Then how were these numbers determined?"
Gu Chen smiled directly and said: "Actually, these identity numbers were set when you were born and registered your household registration. There are 18 digits in total, divided into 4 sections."
"Digits 1 to 6 are address codes. According to my country's administrative division codes, they are grouped in pairs, corresponding to the province, city, and county-level administrative district where your birth was registered."
The girl nodded blankly after hearing this, but her eyes were not looking at the ID card, but staring at Gu Chen's eyes.
Gu Chen pointed to the ID card number, and then said: "The 7th to 14th digits are the date of birth code, and the 15th to 17th digits are the sequential code. They are used to number people born in the same place, the same year, the same month and the same day in order to prevent duplicate numbers.
"
"The 17th digit is an odd number to represent a male and an even number to represent a female. The last digit of the ID number is the verification code, which can be used to verify whether the ID number is authentic."
The girl was stunned: "Then can this ID number be fake?"
"Little sister." Lu Weiwei also saw her receiving the ID card for the first time and couldn't help but said: "With the current level of technology, everything can be fake. Our country's ID card is anti-counterfeiting. You can tell if it is genuine or fake."
"That's right." Gu Chen also nodded and continued: "Then how is the verification code detected? Our country uses the MOD11-2 verification system."
"First of all, each digit of the ID number has a fixed weight coefficient, which is equal to the remainder of 2 raised to the power of 18-i divided by 11, where i is the number of digits in each number."
"Multiply the first 17 digits of the number by the corresponding coefficient and then add them together to get the value S. For example, the value S of the ID number is 221. Divide this S by 11 to get the remainder 1."
"After subtracting the remainder from 12, and then dividing it by 11, the remainder 0 obtained is the value of the check code. The check code obtained in this way ranges from 0 to 10."
“10 will be represented by an
bit, the calculated check code cannot match, and the computer will automatically report an error."
"But please note that if two digits are replaced, it is possible to obtain the correct check code without being able to identify the wrong number."
"So, in order to verify whether you are who you are, digital verification of the identity number alone is far from enough. The ID card itself also needs to be anti-counterfeiting."
Listening to Gu Chen's various explanations, the girl was immediately confused: "When I said comrade police, I blinked and couldn't keep up with the math class, as if I could understand you after you said so much."
"Haha." Officer Wang also smiled and couldn't help but said: "It doesn't matter if you don't understand. Anyway, if you want to prove whether you are you or not, an ID card can do it."
Seeing the girl's half-comprehensive look, Officer Wang added: "Also, since you are a person with an ID card, don't do bad things in the future. As long as you have done bad things and been entered into the system by our police, you will no longer do anything."
There, as soon as we enter your ID number, we can know what you have done."
"Ah?" The girl was also so frightened by Officer Wang that her face turned dark: "Isn't that very unfree?"
"Freedom is relative." Gu Chen said: "When you need freedom, you also need to take responsibility. The ID card can protect you and supervise you, as long as you are a law-abiding citizen."
"Moreover, ID cards now have many functions, and many things need to be done with them, so you must keep them well and don't lose them, let alone sell them to criminals for profit."
"Ah?" When the girl heard this, she was stunned again: "This... this ID card can still be bought and sold? Is there anyone who collects it?"
"Of course." Gu Chen nodded and said seriously: "Some criminals will buy ID cards from migrant workers who are short of money at a price of hundreds or thousands of yuan each, and then use these ID cards.
, to do some illegal activities.”
"So when one day you become a corporate legal person for no reason, or you owe a lot of debt for no reason, don't think it's unreal. It's probably because someone has used your ID card."
"It's too scary." The girl's face froze.
I just wanted to strike up a conversation with Gu Chen, but ended up being educated and explained by three police officers in turn.
It feels like the ID card in your hand now is not an ID card, but a gold bar, worth thousands of gold.
At this moment, Officer Wang's cell phone suddenly rang.
He took the phone and after communicating on the side, he immediately patted Gu Chen and Lu Weiwei on the shoulders: "There is a police situation in Dahe Town, we have to leave immediately."
"Understood." After Gu Chen returned the ID card to the girl, he immediately followed Officer Wang and Lu Weiwei and rushed directly to the parking lot of the compound.
Not long after, a police car with a license plate number ending in AE86 rushed out of the carport like a dragon and drove directly onto the busy street.
On the way, Officer Wang kept communicating on the phone and contacted the relevant police officers at the Dahe Town Police Station to make arrangements.
While Gu Chen was driving, he kept looking at Officer Wang in the rearview mirror. He felt that Officer Wang's expression was extremely serious, as if something important had happened.
The moment Officer Wang hung up the phone, Gu Chen quickly asked him: "Brother Wang, what's going on?"
"There was a murder over there in Dahe Town." Officer Wang paused for a few seconds, then held his forehead and said, "It seems this time is a bit serious."
"Homicide?" Lu Weiwei immediately turned around nervously.
"Stop asking." Officer Wang waved his hand, lay back on his seat, and couldn't help but let out a breath and said, "I'll tell you the details at the scene. I can't tell you clearly now."
Gu Chen nodded, turned on the roof alarm, then put on the gas and accelerated.
As soon as we arrived at the boundary of Dahe Town, there was already a police car waiting at the intersection.
Seeing someone from Furong Branch, a young trainee police officer immediately stepped forward, and Gu Chen also took advantage of the situation and parked the police car on the side of the road.
"Hello, I am Zhang He from the Dahe Town Police Station. You can just call me Xiao Zhang. The director asked me to pick you up."
"Furong Branch, Criminal Investigation Group Three, Lao Wang." Officer Wang introduced himself.
"Criminal Investigation Group Three, Lu Weiwei, this is Gu Chen." Lu Weiwei directly introduced herself to Gu Chen and introduced her to Gu Chen.
Zhang He nodded: "You came at the right time. This kind of thing happened in our Dahe Town, and the director was frightened. So, you follow my car, and I will take you to the scene."
"Okay." Gu Chen nodded.
Afterwards, Zhang He trotted all the way to the car and drove the police car to lead the way. Gu Chen followed him and turned to a fork in the road.
But Gu Chen knew this road. He passed by it on vacation with his parents a week ago.
Moreover, the route Zhang He took seemed to be becoming more and more familiar. When he saw a row of windmills in the distance, Gu Chen's face was startled, and he had an ominous premonition.
And just outside the yard of the windmill house, there seemed to be a large number of people watching.
After Zhang He parked the car, he hurriedly ran to communicate with a third-level police inspector, then pointed at the car where Gu Chen was, and the two greeted him almost at the same time.
Gu Chen parked the car, and the three of them put on their police equipment and got out of the car. A third-level police inspector with a little belly hurriedly stepped forward and greeted: "Old Wang, Lu Weiwei, Gu Chen, so it's you?"
"Lao Gao, what's going on?" Officer Wang put on his police hat and looked a little serious.
Director Gao shook his head and said, "You will know after you go to the scene and see it. Come with me."
Seeing that Director Gao didn't want to mention it in a crowded place, everyone understood it.
So under the leadership of several police officers, some of the onlookers were dispersed and a passage was opened.
Several people got through the cordon and came directly to the compound.
"Windmill Resort Hotel?" Gu Chen couldn't help but read the name.
"Yes." Director Gao also said as he walked: "This hotel used to be a good business, but then it stopped and there were few tourists, so we rented these characteristic windmill rooms to some outsiders at a very cheap price.
live."
"But just last night, something like this actually happened. Now the whole village, as well as Dahe Town, everyone is spreading the word about it. There is a lot of pressure from public opinion."
At the same time as Director Gao was introducing him, Gu Chen discovered among the crowd the old lady who had booked a room for Gu Chen, and immediately walked up to her.
"Old lady, we meet again."
Looking up at Gu Chen, the old lady seemed to have some impression, but she couldn't remember it for a while. She could only say awkwardly: "Young man, it seems we have met before, right?"
"Not only have I seen it, but I also know that you manage this Windmill Resort Hotel and you are responsible for booking rooms."
Hearing what Gu Chen said, the old lady seemed to have some impression. After thinking about it for a few seconds, she finally said: "I remembered that you came for vacation with your family that day, and I opened a room for you.
"
"Yes." Seeing that the old lady was not confused and was within the cordon, Gu Chen immediately guessed that the police needed the old lady's cooperation.
"Gu Chen, do you know Aunt Zhang?" Director Gao also knew Aunt Zhang from the Windmill Resort Hotel when Gu Chen first came to the avenue, and he was stunned for a moment.
Gu Chen nodded and said, "I lived here a week ago."
"Oh, that's it." Upon hearing this, Director Gao said calmly: "Then you must be very familiar with the situation here."
"Almost." Gu Chen didn't say too specifically, but while following Zhang He forward, he found that a cordon had been drawn at the door of Windmill House No. 9. He was stunned for an instant, and his legs stopped there.
.
"What...what's wrong? Junior Brother Gu?" Seeing Gu Chen's abnormal mood, Lu Weiwei couldn't help but look at her curiously.
"Wan Xin?" Gu Chen frowned. After thinking carefully, he looked up at the house number and said, "Yes, this is Wan Xin's house. She only rented here half a year ago."
"Wan Xin?" Everyone present was shocked when they heard that Gu Chen could even name the residents of No. 9 Windmill House. It felt as if Gu Chen was far away in Furong Branch and knew the scene better than all the police at the scene.
