As soon as Long Xiang finished speaking, Tang Wei stood up and cheered loudly:

"It's hard to say what's going to happen in the future, but I believe in Yun Qi's reasoning. How can you manage a large number of people? I can barely hold on here, but Chief Cao is extremely busy all day long."

"The problems you two have are actually discussed together."

Long Xiang nodded lightly, then said with empty eyes: "If the three hundred soldiers can be distributed properly, it is actually barely enough. As for the large number of refugees and their chaotic living, management must be done in a methodical manner."

Cao Xing stood up quickly, clasped his fists and reminded: "Sima, it doesn't matter if there are any troubles. The key is that as the refugees continue to pour in, many of them will mix in with thieves and bandits. If you don't take strict precautions, the consequences will be disastrous.

The general is responsible for external security, but there are only a dozen horses available. I am worried that the general will not be able to exert his full strength in case of trouble, and he is afraid that it will ruin your big event."

"Yes, yes, Director Cao is right. I sent people to supervise their brick making, and also sent people to patrol around the city, just to avoid bad guys getting in." Tang Hui quickly agreed.

Long Xiang motioned for the two of them to sit down and comforted them with a smile: "Using stupid methods is time-consuming and labor-intensive, and the results are not pleasing to the eye. Let me think about what is better..."

After Tang Wei and Cao Xing sat down, Long Xiang stood up instead.

After walking back and forth for a few steps, he suddenly saw the 'house plan' on the ground, and inspiration immediately came to his mind.

Then he bent forward to pick up the branches and wrote Arabic numerals on the ground - 1234567890.

"You all come here and take a look, especially Master Cao. You must keep these figures in mind."

Long Xiang specifically pointed at Cao Xing to remind him.

Cao Xing was confused when he heard it, and he was even more puzzled after seeing the strange symbols on the ground.

"Sima, these are all..."

Long Xiang explained: "They each represent ten digits. In the future, when you compile household registration information, you will use these symbols to replace the original numbers."

Cao Xingxin said, "What new symbol did you come up with out of nowhere? Can you use these to solve the personnel problem?" So he politely reminded: "This symbol..."

Long Xiang asked back: "Does Master Cao remember his birthday?"

Cao Xing's head was like a chicken pecking at rice, and he replied: "Of course I remember that Mo will be born in the third year of Jianning, on August 15th."

"Very good, come and see."

Long Xiang waved to Cao Xing, and at the same time wrote nine numbers 081511001 on the ground, and then gave explanations one by one.

"Everyone has a birthday. The first four symbols represent your birthday. The symbol 0815 is August 15th;

The odd number in the fifth digit is male, the even number is female, choose any number to distinguish the gender;

The sixth digit represents occupation and status. I temporarily use 1 to represent soldiers, and 234 can represent farmers, businessmen, craftsmen, etc.;

The last three digits are the record number. If Uncle Wei was born on the same month and day as you, he is also a soldier, but because he was registered after you, his number should be 081511002."

"My birthday is not August 15th, but June 3rd." Tang Hui quickly corrected.

Long Xiang nodded bitterly, "I'm giving an analogy to Chief Cao..."

"It's a bit difficult, it takes some time to understand..."

Cao Xing frowned and scratched his head and ears. He suddenly felt that his brain was not enough, and it became increasingly uncomfortable for him to be the chief clerk.

Feng Zhong seemed to understand after hearing this, and asked curiously: "Yunqi, what are you doing with these symbols?"

Long Xiang replied sternly: "This is the unique identity symbol I have assigned to the people of Hefei. As long as the registration is carried out strictly according to the requirements, I believe everyone's symbol will be different."

"Even if everyone has different symbols, what's the use?" Tang Hui looked confused.

Long Xiang explained with a smile: "Uncle Wei is responsible for city defense and checks people entering and leaving the city every day. Isn't it troublesome?

If we number the people individually and then write or embroider the characters on their clothes, they will need to check their birthdates before they can be released.

If you meet someone who is particularly suspicious, you can also check the statistical manuscripts. How can I be fooled so easily?"

"It seems a bit powerful, but I'm afraid I won't be able to learn..." Tang Wei shook his head gently.

"This matter is related to the security of Hefei. The meaning of the symbols cannot be known to ordinary people. You need to select flexible and stable people in the army, and I will personally teach them how to use it."

The method Long Xiang came up with was based on the ID card number rules, but he improved it according to the actual situation. He plans to optimize it while using it in the future to make it a true three-country ID card.

Arabic numerals had not yet appeared at this time, so Long Xiang used Arabic numerals instead of traditional Chinese characters, which was equivalent to encrypting the number.

As long as the city guards understand the rules of symbols, they can use the symbols on their birth dates and clothes to deal with this. If craftsmen and criminals cannot decipher it, they can only wait to be caught.

Tang Wei still didn't understand. He tilted his head and questioned: "Can you use this symbol to grasp the details?"

Long Xiang nodded solemnly, "From now on, the north gate of Hefei will only be closed. That is to say, the new arrivals will not be checked with their serial numbers. They will be sent to work in making bricks and kilns, repairing city walls, transporting goods, etc. Those who perform well within three months will

, and then issue a Hefei resident identity number. Once you have the number, you can enter and exit the South Gate to work. We will wait for the details to be implemented and improve them as they are implemented..."

"I probably understand, that is, if you match the number, you are a good person?"

"That's pretty much it."

"Sounds very good. Let Xizuo work for three months in vain, and it will probably show flaws."

Feng Zhong nodded in affirmation and continued to ask: "Determining numbers sounds easy, but do you want to compile it into a book? Chief Cao is probably too busy. He is now in charge of the outpost outside the city..."

Cao Xing glanced at Feng Zhong gratefully and said to himself that finally someone spoke for me. The paperwork was really overwhelming and it felt more tiring than going to the battlefield.

Long Xiang patted Cao Xing on the shoulder and comforted him: "The difficulty is only temporary. Our Hefei is a county. To manage a county well, the four of us alone are not enough."

Pay more attention when doing statistics to see if there are any young and smart people, and train a few more assistants to help.

In addition, there are refugees entering the city every day, and there are probably some literate among them. Such down-and-out scholars should be used for their own purposes, and they should keep their eyes open to discover."

"oh..."

Cao Xing answered without confidence.

Long Xiang talked for a long time and suddenly felt more relaxed.

Seeing that a few people were still reminiscing, Long Xiang waved his hand and said, "Go and select someone. The sooner someone learns how to use these symbols, the easier it will be for everyone."

"Oh okay."

Tang Yi clasped his fists and was about to leave. Feng Zhong looked at the 'house plan' on the ground and reminded Long Xiang: "Yunqi, let Mr. Cao draw this picture? Don't look back and forget it in the busy schedule."

Long Xiang pointed to his forehead and said with a smile: "There are not many old paper and ink books found in Hefei. Now I use as little as possible. I have to save as much as possible. Besides, this is just a sketch. I will optimize it carefully later.

, Uncle Zhong, don’t worry, they are all in my mind.”

"That's good." Feng Zhong nodded with satisfaction.
