As soon as Long Xiang's words fell, Tang Yu got up and cheered loudly:

"It's hard to say what will happen in the future, but I believe in Yunqi's inference, how to manage it if there are too many people? I can barely hold on here, but Master Cao is too busy all day. ”

"The questions of the two of you are actually discussed together."

Long Xiang bowed his head slightly, and then said with a weak eye: "If the three hundred soldiers can be properly distributed, it is actually barely enough, as for the many displaced people and the messy residence, the management must be based on ways and means." ”

Cao Xing hurriedly stood up and reminded with his fists: "Sima, it doesn't matter where the trouble is, the key is that with the continuous influx of displaced people, many of them are mixed with thieves and meticulous work, if you don't take strict precautions, the consequences will be unimaginable."

The last general is in charge of external guard, but there are only a dozen horses available, so he is worried that he will not be able to go all out in case of trouble, and he is afraid that he will spoil your big thing. ”

"Yes, yes, Master Cao is right, I sent people to supervise them to make bricks, and I sent people to patrol around the city, just for fear of mixing in with bad guys." Tang Yu hurriedly agreed.

Long Xiang motioned for the two to sit down, smiling and comforting: "Using stupid methods is time-consuming and laborious, and the effect is not pleasing to me, let me think about how to live..."

After Tang Yu and Cao Xuan sat down, Long Xiang stood up instead.

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

Then bend down and pick up the branches, and write the Arabic numerals on the ground, 1234567890.

"You all come over and take a look, especially Master Cao, you have to keep these few figures in mind."

Long Xiang specifically pointed to Cao Xing and reminded.

Cao Xing was at a loss when he heard this, and he was even more puzzled after reading the strange symbols on the ground.

"Sima, these are..."

"They represent ten digits, and in the future, you will use these symbols instead of the original numbers when you count your household registration information," Long explained. ”

Cao Xingxin said that you are inexplicably engaged in new symbols, and these can solve the personnel problem? So he tactfully reminded: "This symbol..."

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

Cao Xing's head was like a chicken pecking rice, and he replied: "I naturally remember that the last general was born in the third year of Jianning, on the 15th day of August. ”

"Very well, come and see."

Long Xiang beckoned to Cao Xing, and at the same time wrote 081511001 nine numbers on the ground, and then explained them one by one.

"Everyone has a birthday, and the first four symbols represent your birthday, and the symbol 0815 is August 15;

The fifth odd digit is male and the double number is female, and any number is selected to distinguish gender;

The sixth digit represents occupation and status, and I temporarily use 1 for soldiers, and 234 for farmers, merchants, craftsmen, etc.;

The last three digits are the record number, if Uncle Yu was born on the same day and month as you, his identity is also a soldier, but because he is registered behind you, his number should be 081511002. ”

"My birthday is not the fifteenth day of August, but the third day of the sixth month." Tang Yu hurriedly corrected it.

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

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

Cao Xing frowned, scratched his ears and cheeks, he suddenly felt that his brain was not enough, and he was becoming more and more uncomfortable as the master book.

Feng Zhong listened to it and asked curiously: "Yunqi, what are you doing with these symbols?" ”

Long Xiang Zhengse replied: "This is a unique identity symbol for the people of Hefei, as long as it is registered in strict accordance with the requirements, I believe that everyone's symbol is different." ”

"What's the use of each person's symbols, even if they're different?" Tang Yu's face was full of doubts.

Long Xiang explained with a smile: "Uncle Yu is in charge of the city defense, and it will be very troublesome to check the people entering and leaving the city every day?"

If we number the people separately and write or embroider the characters on their clothes, we need to check the birthday of the people and then we can be released.

If you encounter a particularly suspicious person, you can also query the manuscript of the statistics, and ask how to easily confuse the details? ”

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

"This matter is related to the safety of Hefei, the meaning of the symbol cannot be known to ordinary people, you need to pick out people in the army who are flexible and steady, and I will personally teach them how to use it."

The method that Long Xiang came up with was with the help of ID card number rules, but it was improved according to the actual situation, and he planned to optimize it while using it in the future to make it a real ID card of the three countries.

Arabic numerals did not appear at this time, and Long Xiang replaced traditional Chinese characters with Arabic numerals, which was equivalent to encrypting the number.

As long as the guards of the city master the law of symbols, they can use the symbols on their birthdays and clothes to do this, and the fine work and lawbreakers cannot decipher it, so they can only wait to be caught.

Tang Yu still didn't understand, he tilted his head and questioned: "Can you use this symbol to grasp the details?" ”

Long Xiang nodded solemnly, "After that, the north gate of Hefei can only enter and exit, that is, the new arrivals do not check the number, and send them to dry brick kilns, city wall repairs, transportation of goods and other work, and those who perform well within three months will be issued Hefei resident identification number, and you can enter and exit the south gate to work with a number.

"I probably understand, that is, the number is a good person?"

"That's pretty much it."

"It sounds very good, let the fine work for three months, it is estimated that the flaws will be exposed."

Feng Zhong nodded in affirmativeness and continued to ask: "Numbering sounds easy, but what you mean is still to be compiled into a book?" Master Cao is probably too busy, he is now in charge of the sentry outside the city..."

Cao Xuan glanced at Feng Zhong gratefully, and said in his heart that finally someone helped me speak, these paperwork is really big, and I feel more tired than going to the battlefield.

Long Xiang patted Cao Xing's shoulder and comforted: "The difficulties are only temporary, our Hefei is a county, and to manage a county well, it is not enough to rely on the four of us."

You pay more attention to the statistics to see if there are any young and smart people, and train a few more assistants to help.

In addition, there are displaced people entering the city every day, and there are likely to be literate among them, and this kind of down-and-out scholar must be collected for his own use, and he must keep his eyes open to find out. ”

"Oh..."

Cao Xuan replied with little confidence.

Long Xiang said a lot, and suddenly felt a little more relaxed.

Seeing that a few people were still reminiscing, Long Xiang waved his hand outward: "You guys go and pick people, someone will learn to use these symbols earlier, and everyone will be more relaxed." ”

"Oh good."

Tang Yu clenched his fists and was about to leave, Feng Zhong looked at the 'house plan' on the ground, and reminded Long Xiang and said, "Yunqi, let Master Cao draw this picture, right?" Don't look back and forget. ”

Long Xiang pointed to his forehead and said with a smile: "There are not many old paper and ink books turned out in Hefei, now I use a little less, I have to save as much as possible, and this is just a sketch, I will carefully optimize it when I come down, Uncle Zhong, you don't have to worry, they are all in my mind." ”

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

Seeing this, Tang Yu joked to Feng Zhong: "In addition to this Hou Mansion in Hefei, there are four larger houses in the city, if you want to live in a big house, just find someone to clean up one, why worry about a new house?" ”
