Yan Shiyue was not polite either. He directly told Ding Xiaoyan to prepare limestone and white coal in front of them, and then took the two of them to the study and called the fourth prince: "Fourth brother, write what I say."
The Fourth Prince was very proactive. He immediately rolled up his sleeves, ground ink, and picked up the pen.
Yan Shiyue tried hard to recall and integrate the knowledge in his mind before saying: "In flood-prone areas, the most important thing is to prevent various diseases, so you must pay attention to disinfection."
Disinfection requires bleaching powder, the main component of which is calcium hypochlorite. To prepare calcium hypochlorite, limestone and white coal need to be intermittently added from the top of the lime kiln in a ratio of 1: (0.11-0.13) to the lime kiln for calcination, and the temperature needs to be controlled at 800-1200°C. The generated lime is intermittently discharged from the bottom of the kiln, and water is added to digest it to obtain slaked lime containing a small amount of free water, which is aged for more than eight days and sent to the air separation system for slag removal through an auger.
The powdered slaked lime is separated into gas and solid phases by a cyclone separator. Fine slaked lime containing 3% to 6% free water is added from the fourth floor of the chlorination tower through the auger under the slaked lime bin, chlorine (liquid chlorine liquefied tail gas) is introduced from the first floor of the chlorination tower, and the bleaching powder product is discharged from the first floor of the chlorination tower①.
This process is very complicated for this era, and a lot of equipment needs to be researched and produced. Even if it is urgent, it will take at least ten days or half a month to complete.
Therefore, currently, you can use simple boiling disinfection.
Then, remember that diseases come from the mouth, for example, do not eat drowned animals, do not eat soaked food, do not drink unboiled water... etc. This can be directly made into a jingle and taught to the people to sing.
In addition, the disinfection of feces, corpses, etc., and the extermination of mosquitoes, flies, and rats after the disaster are also top priorities.
She said a lot and in a confusing manner. After the Fourth Prince finished taking note, he exchanged glances with the Crown Prince. Both of them felt complicated.
...
...
Indeed, Princess Fuyan has never met anyone's expectations, nor has she ever disappointed anyone.
Disaster relief, who should be called from among the civil and military officials? The first priority is water control, such as strengthening dams and diverting rivers. The second priority is, of course, epidemics. Bring the imperial physicians to treat the disease and appease the people...
But what she meant was "prevention", prevention and treatment of epidemics.
The prince hesitated for a moment.
The fourth prince took another piece of paper to sort it out. It was the first time he witnessed a miracle with his own eyes, and his expression was vaguely excited: "Anything else?"
Yan Shiyue thought about it carefully.
The first thing she thinks of is always modern disaster relief methods.
But is there nothing good about the ancients’ disaster relief efforts?
Yes, of course.
Fan Zhongyan, a famous official in the Northern Song Dynasty, took several measures to provide disaster relief that were extremely bold and ingenious.
For example, he was the first to propose "work-for-relief".
She has always strongly agreed with this idea and has discussed it with the Fourth Prince.
Moreover, he encouraged the local area to hold more competitions, and he himself took the lead in participating and encouraged them. At the same time, he summoned the abbots of various temples and told them that during the years of famine, the labor price was the lowest, and the temples could take this opportunity to renovate the temples.
The hosts all agreed with this and seized this rare opportunity to recruit refugees to work, paying them very little wages and providing three meals a day, and the refugees flocked to them.
Government officials, merchants, and wealthy families also saw the opportunity and began to build large-scale projects. The victims had food to eat and things to do, and the situation naturally became stable.
Also, when times like this come, there is not enough food for disaster relief, and there are always those unscrupulous businessmen who drive up prices, hoard goods, and try to profit from the national disaster.
He asked people to spread the word in the surrounding counties and prefectures, saying that the current price of rice in Wuzhong was 180 wen per dou, and those who wanted to get rich should hurry up!
When foreign merchants saw the profit to be made, they were tempted and immediately organized to transport large amounts of grain over.
After countless grains were delivered, market leverage began to take effect as prices competed against each other. The high grain prices immediately fell, which not only solved the food shortage in the disaster-stricken areas, but also dealt a heavy blow to those unscrupulous businessmen who attempted to profit from the national disaster.
What she said was still a little confusing, but the Crown Prince and the Fourth Prince were already shocked to the point of being speechless.
You know, a talented person may not necessarily become an official.
In this day and age, there are very few people who understand economics.
Fan Zhongyan's economic thinking was impeached by countless people at the time, who accused him of being unsympathetic to famine, indulging in fun and entertainment during disasters, building large-scale projects, and wasting people's money and labor.
Including the Crown Prince and the Fourth Prince, they were a little confused at first.
But when she sorted out her thoughts and told the consequences, the Crown Prince and the Fourth Prince were not stupid and naturally understood.
Now that I understood, all that was left was admiration.
Then Yan Shiyue was brought into the palace by the two men. Emperor Ming Yan was shocked after listening to what they said in detail.
Let’s not talk about this “disinfectant powder” for now, the subsequent measures are very wise.
The key to raising funds for events and large-scale construction is to "employ people" and to raise private financial resources to benefit the local area. This not only provides disaster relief but also comforts the people, with immediate results. For the local people, everyone is happy, and for the court and the government, it is a win-win situation.
If before the imperial court was the one who bore the burden of disaster relief for the people, now it has become a promoter and guide, making full use of the local "surplus wealth" to appease the local people.
This opened the door to a new world for him.
Moreover, Yan Shiyue, who proposed these things, indeed made him look at him with new eyes.
Emperor Ming Yan glanced at the little girl who was looking down.
She had just been shouting that she had not had lunch, so she asked Gu Jiuxing to bring her a bowl of noodles. She was sitting by the window eating it like a little squirrel.
Although she had many eccentric talents before, they were all "technical". It was not until this time that he realized that what was in her brain was indeed worth exploring.
It was at this time that he became determined to let Yan Shiyue enter the court. When he looked at her, he had almost figured out what official position he would let her hold and what she would do in the future.
Emperor Mingyan smiled slightly and said, "Crown Prince, go ahead. Silang, you organize people to make this disinfectant powder. Yue'er, you help your fourth brother."
Yan Shiyue didn't notice anything was wrong at all and responded while biting her cheeks.
Then the prince left first. After she finished her noodles, she left the palace with the fourth prince and immediately organized people to prepare disinfectant powder.
The Fourth Prince always did things personally, and she also took the lead in important matters. The two of them organized the staff very quickly, and then rushed to make cyclone separators and other equipment.
The two of them, along with a group of craftsmen, worked non-stop for several days, and after several failures, they finally started production. They didn't feel relieved until the aging stage.
Although the flood was a serious matter, it was far away after all, and life in Chang'an City went on as usual.
During dinner, Yan Shitu asked Yan Chengyuan: "Dad, where are Yue'er and the Fourth Prince now?"
Before Yan Chengyuan could answer, Meng Min said, "Yue'er came back around noon today and said she would come over for dinner in the evening. Why hasn't she come yet?" While asking someone to urge her, Meng Min asked him, "Why did you think of asking Yue'er? What did you want to see her for?"
