The First Family of Tang Dynasty
Chapter 2234: This kid, this is trying to stab God...
The population growth model, also known as the population transition model, reflects the law that the birth rate, death rate and natural growth rate of the population in different countries and regions change with the changes of social and economic conditions.
According to the characteristics of natural population changes, the general process of population growth can be divided into four stages.
It reflects the process of changing the population growth model from the "primitive type" with high birth rate, high death rate and low natural growth rate to the "modern type" with low birth rate, low death rate and low natural growth rate.
The four data sheets in front of Cheng Chubi marked the population growth of the four regions of Chang'an, Jinyang, Luoyang and Luzhou that he knew.
Just like this Datang Chang'an City, in recent years, Datang has paid attention to the development of medical careers, and with the rapid growth of medical workers.
As a result, the mortality rate in Chang'an City has shown a decreasing trend, and with the prosperity and development of the society, coupled with the people's living and working in peace and contentment, and the improvement of production and living standards.
In recent years, the population growth of Chang'an has surpassed that of the ten years at the beginning of Zhenguan.
Cheng Chubi tried his best to introduce and analyze the natural factors, economic foundation, superstructure and decisive factors of population growth in a language that people of this era could understand.
Li Shimin stared blankly at the data sheet, and then looked at Cheng Saburo, who was talking eloquently in front of him, poking his fingers on the data sheet.
My heart was full of shock. I originally thought that this kid was slack and dereliction of duty during this time, and only knew how to play cards.
But he never thought that he would come up with these things secretly.
Although Li Shimin only heard this knowledge for the first time, it did not prevent the wise man of the Tang Dynasty from following Cheng Chubi's statement.
After understanding these data charts, you can really visualize and intuitively make people aware of the current demographic trends in Datang.
Following Cheng Chubi's remarks and gestures there, Li Shimin's eyes repeatedly browsed on the four very intuitive and vivid data sheets.
Sure enough, the problem was quickly detected. Compared with the other three graphs, the population growth curve appeared to be slowly rising.
Luoyang's population growth curve is very strange, especially in the population growth curve, the death rate, birth rate, and the natural growth rate of the cuboid are not much different from the other three cities.
However, his population growth data curve has remained at a low level all the year round, and only in recent years has there been a sudden mutation.
Just when Cheng Chubi started talking and was about to go straight to the point of the problem, he saw Li Shimin's big slap raised, and he couldn't help being stunned.
#####
Li Shimin glanced at all the important officials who looked solemn at the moment, craned their necks to look at the data table here, and said solemnly.
"Fang Qing's family, Tang Qing's family, the two of you stay here. All the Qing families, today's affairs, we will discuss tomorrow..."
With this order, those ministers could only stand up, bowed respectfully towards Li Shimin, and exited the Wencheng Hall.
It's just that when they left, those pairs of meaningful eyes swept across Saburo repeatedly.
Just a few steps out of the Wencheng Hall, the courtiers with the background of the aristocratic family couldn't help but speed up a few points.
The eldest grandson Wuji and Chu Suiliang deliberately fell behind.
"Mr. Zhao, I suspect that this matter is not so simple..." Chu Suiliang stroked his long beard and looked worried. But for the sake of obstructing him for serious things, he didn't bother to bother with him.
The two came to the next room where they were arranging drawings and compiling the origin and properties of medicines.
I met Mr. Hu, who was suspended from the Imperial Physician's Office and came to teach at Cheng's University.
"I've seen Mr. Hu, this is the Prince Zhan Shi Yu Zhan Shi, who came with me today.
Gu </span> Just wanted to ask how the compilation of the "Guanzhong Pharmacopoeia" is going? "
"You two, don't worry, this old man, Teacher Zhang, and the disciples have already revised and edited the content to the same extent."
"The rest is to wait for the design of the medicinal materials. If it is expected, it will take about ten days to complete the book."
Hearing the good news, Cheng and Yu couldn't help smiling, and after chatting with Mr. Hu for a few more words, the two stopped disturbing and resigned.
"In ten days, I can't imagine that it can be so fast. In this way, we can completely submit this "Guanzhong Pharmacopoeia" within this year."
Hearing the words of Yu Zhan, who was so excited that he rubbed his hands frequently, Cheng Chubi nodded in agreement.
It will take about ten days to complete the draft of the Pharmacopoeia within the Tang Dynasty. When that time comes, I will pass it to the top after passing through His Royal Highness.
His Majesty will definitely be delighted by Long Yan. At that time, His Royal Highness will be able to take the heavy responsibility of compiling the Datang Pharmacopoeia under this pretext.
Although he Michelin King Wei presided over the compilation of "Guodizhi", but that thing is mainly an official reference book.
Books like this "Datang Pharmacopoeia" are completely good treasures that have merit in the present and benefit in the future.
Think about it, if there are thousands of doctors in the Tang Dynasty, if everyone can have one copy, it will not only improve the doctors' medication and knowledge of medicine.
At the same time, it can also include more medicines for curing diseases, so that more people in the Tang Dynasty can relieve their pain.
#####
When the two of them came not far from the principal's room, they heard the sound of playing cards from inside.
Yu Zhining's face darkened slightly, and finally stopped. He turned and left on the grounds that he was going back to the East Palace to report the good news to His Royal Highness the Prince.
Cheng Chubi eagerly sent Yu Zhanshi to the door of the university, and UU Reading www.uukanshu.com saw not far away, several bullock carts were heading here.
"Master, master, the iron stove you ordered is here!" The leader was Uncle Ji, the chief administrator of Cheng's University.
"Iron stove?" Yu Zhining, who was about to ask someone to bring his mount over, was stunned for a moment, and turned his head to look over there.
I saw four or five iron objects with very strange shapes on the two bullock carts in front.
The two bullock carts in the back were filled with peat, which once burned, smelled very unpleasant.
Even blacksmiths don't like to use it, mainly because it has a lot of impurities, too much smoke, and a strong smell.
That is, poor people have to use this cheap and cheap peat as fuel.
Cheng Chubi laughed, nodded with satisfaction and replied.
"That's right, it's an iron stove for burning peat. If the students at the school hadn't already started heating the fire, I would have almost forgotten about this big killer."
"General Cheng, are you... for those students?"
Yu Zhining's tone couldn't help but feel a little more displeased.
"Isn't that appropriate? Even if those students can't pay much for a year's tuition, you don't need to do this, General Cheng."
