Chapter 278
Li Shimin led a group of people and hurried to the study.
Su Jin was stunned, she hadn't thanked him yet!
Princess Changle smiled, "Jin'er, let's go, father and others must have something important to discuss!"
Jin'er nodded and followed Princess Changle away.
...
"What is the use of the ID number, and where does this number come from?
Tell me in detail!"
After arriving in the study, Li Shimin couldn't wait and pointed to a string of numbers on the household registration book and asked.
Li Yuan, Li Chengqian and Su Chen sat on one side of the desk.
Li Shimin, Changsun Wuji, Fang Xuanling and Du Ruhui sat in a row.
"Your Majesty, the ID number, as it is obvious, is the ID number.
You can see it by looking at your own ID card.
The numbers on it are the same, and the number of each ID card is unique."
Li Shimin picked up Li Tai's ID card casually, and in his opinion, the string of numbers seemed to be nothing special.
"What does this lowercase number mean?"
"It means a lot. For example, there may be two people with the same name and surname in a village who were born in the same year and month.
But the ID number is unique and can distinguish one more accurately.
As for how that number came about, it has to do with the administrative division. Please look behind you."
Su Chen spent nearly two days to draw this big map.
It marked more than 1,550 county names in the Tang Dynasty, and each administrative district was marked with a corresponding number.
Li Shimin and the three civil officials immediately stood up and looked behind them.
I saw a large piece of paper hanging on the wall, which was exactly the size of four newspapers laid flat.
Li Yuan and Li Chengqian also followed up to check.
"This... This is a map of the Tang Dynasty, so detailed!"
"Hahaha, good, good!"
Li Shimin did not ask who made it. He didn't believe anyone else could do it except Su Chen.
Su Chen then remembered that he had forgotten to give a title.
They always say this is a map, which is not something I am used to hearing.
Li Shimin and others looked at the map quietly for more than ten minutes.
"Your Majesty, this is Western Turkic, this is Tubo... How can Tubo be so vast?"
"There are more than 40 small countries in the Western Regions?"
Li Shimin nodded silently, and his heart was suddenly filled with ambition.
'Everything shown on the map will belong to me! '
He turned to look at Su Chen, and did not speak, just looked at it quietly.
Su Chen felt a little uneasy when he was looked at, and stood up quickly.
"Your Majesty, if you have something to say, just say it! I am unsure when you look at me like this!" Su Chen "cried".
"Haha!" Li Shimin was amused.
"Well, can I take this map back to the palace?
I want to frame it and hang it in the imperial study, and watch every inch of the land of the Tang Dynasty every day."
Li Shimin said in a relaxed tone.
"Of course, I made it so big so that it would be easy for people to copy it for embroidery, so that it can be preserved for a long time.
This kind of paper is not durable and easily damaged."
"Okay, you are really careful. Now tell me, how do you explain the mark 10 in the imperial city and 11 in Chang'an County."
Li Shimin turned sideways and pointed to the area where Chang'an belonged.
"Whose ID card are you holding?" Su Chen asked this question without thinking there was anything wrong with it.
We are all human beings.
"Qingque." Li Shimin replied immediately.
"Then your majesty, look, are the first two digits of Li Tai's ID card 11, which represents Jingzhao Prefecture.
Are the last two digits 01? As shown in the picture, 01 represents the capital Chang'an. 10 represents the imperial palace, and if it is a citizen of Chang'an County, it is 11.
This is the meaning of the first six digits of the ID card.
Do you understand what I said?"
Li Shimin took the ID card and looked at the map to check carefully.
After thinking for a while, he asked:
"If we take Xue Rengui as an example, the first six digits of his ID number are: 131212?"
Li Shimin converted Xue Rengui's place, Longmen County, Jiangzhou, Shanxi, into six digits for verification.
How could Su Chen remember the administrative area code he had made up temporarily? He went forward to look it up.
"Yes, that's right!" he replied after confirming that it was correct.
Li Shimin nodded and handed the ID card to Su Chen.
"I will not ask any more questions. You will explain these numbers to me one by one."
Su Chen looked at his watch, "Your Majesty, please wait a moment. I will ask Wang Xi to find a blackboard. It will be easier to explain it that way."
Li Tai was not in the study, so Su Chen did the hard work by himself.
After a while, two servants brought the wooden blackboard into the study.
Picked up the chalk and wrote his ID number on the blackboard.
At this time, six "students" were sitting in front of Su Chen.
They were waiting for Su Chen to give a lecture very seriously.
"Classmates, as you can see, this is my ID number.
I registered my household registration in ChangAn County, I don't even know what the place I lived in before was called.
I have already explained the meaning of the first six digits. Do you understand?"
Everyone nodded.
"Well, then I will continue to explain the last two digits. Next time you have to answer "I understand" and I will continue. "
"Everyone knows that I am 16 years old this year, but the Tang Dynasty was founded only 11 years ago.
Therefore, Li Tai and I use the sexagenary cycle to indicate the year of birth before the first year of Wude.
The sexagenary cycle is a sixty-year cycle, with Jiazi as the first, so the year I was born should be: Renshen year corresponds to 09.
From this, the first eight digits of my ID number are: 11011109
Everyone, do you understand this? "
Everyone said in unison: "I understand."
Su Chen nodded and continued to explain...
"The next four digits represent the year of the Tang Dynasty. If the people were born after the Wude year, they would not need the sexagenary cycle.
For example, the year of Li Zhi's ID card number is represented by 0006. "
"Why is the Tang Dynasty not a two-digit year?" Li Shimin asked the same question as Li Tai.
"Haha, your majesty, think about it.
The largest two-digit number is 99. Will the Tang Dynasty end after a hundred years?
So it is best to use four digits here. Isn't it often said that the Tang Dynasty will last for ten thousand years?"
After turning the corner, Li Shimin stood up immediately.
He shouted loudly with heroic spirit:
"Well said! Use six digits. I want the Tang Dynasty to be passed down for 100,000 years!"
Su Chen's mouth twitched.
"Six digits are just right. Isn't there a two-digit year in front of it for the sexagenary cycle? At most eighty years, people born before the Wude year are almost dead."
Li Shimin's eyes lit up, as if it was really the case.
"Dead? What do you mean?"
"Oh, dead means no longer in this world. "Su Chen answered casually.
…
It was probably less than ten minutes.
Su Chen explained the origin of the ID card number.
"Your Majesty, if you want to use the household registration book and ID card, you must understand that you must have a household registration book before you can have an ID card.
In other words, when a person is born, he must go to the government to register his household registration and determine the ID card number.
At the age of six, he can apply for an ID card, which is valid for ten years.
After ten years, the card must be replaced.
Li Shimin nodded and suddenly asked: "Why do you need to replace the card?"
"Because people's appearance will change with age, so the ID card must be replaced."
"Especially teenagers!"
