"Why didn't Cheng join the army today?" Wu Yanzhi asked.

"Tell King Donglai, Zhao joined the army and asked for leave today. His wife gave birth to a baby boy a few days ago, and he was all right, but he suddenly got seriously ill last night and died! His wife cried to death! Another Zhao member of the army reported.

"Oh, what's the disease? Why is it so dangerous? ”

"I don't know about this humble position, I have invited the best senior doctor in the city, but I still haven't been saved!" Zhao Sanjun reported.

Wu Yanzhi not only frowned, but suddenly remembered something: there was a shortage of doctors and medicines in this ancient world, and there were no antibiotics. Now that he is a assassin, he still has to do something practical for the people.

I was born more than a thousand years later, and although I can't produce antibiotics for the time being, it would be better if this hygiene knowledge was popularized first.

Just tell the people some simple hygiene knowledge, and sometimes it can also relieve the huge burden of the family.

Thinking of this, he said: "Zhao joins the army, you go and call Zhang Hucao, I will arrange one thing for him, this matter is very important, you can also do it!" ”

"Yes." He bowed his hand and went out.

The positions in the army in this state basically have no specific affairs, and they are the first officials of the newly released officials.

Of course, there are also some who have been promoted to this position by county lieutenants. Because this official position is, after all, higher than that of some county lieutenants.

This Zhao joined the army, and he was the son of Jinshi Keji, named Zhao Yu, 29 years old. This was considered young at that time among the Jinshi and the first. Wu Yanzhi likes him quite a lot.

(As mentioned earlier, Cao joining the army is different from joining the army, and his status is much higher than joining the army.) It is equivalent to Liucao joining the army as the director, and ordinary joining the army as the assistant to the director.

Of course, ordinary military participation is under the direct jurisdiction of the assassin history, not under the jurisdiction of the Cao army. Usually four people in an upper-class state are in the army. ）

……

Half a month later.

Xingzhou Prefecture Ya, two halls.

Wu Yanzhi looked at the report sent by Zhang Yun when Sihu joined the army, not only frowned.

This report is also an ordinary public sentiment report, and the neonatal mortality rate in it is very high, and there is a shortage of medical care and medicine in many places, and the mortality rate is also very high.

This report was asked by Wu Yanzhi to investigate. He was a little worried, it seems that in ancient times, people did not pay much attention to daily hygiene.

The disease is mainly prevented. At this time, although there are no antibiotics, some diseases are difficult to treat.

However, if the hygiene measures are done well, the chance of getting sick can be greatly reduced.

"Zhang Hucao, you go and call Jia Sima over!" Wu Yanzhi commanded.

"Yes."

After a while, Sima Jia Jue of Xingzhou was led in by Zhang Hucao.

After saluting, Wu Yanzhi arranged: "I asked Zhao Senjun to make up some slips, you can wait and take a look." ”

Zhang Hucao took a look: drink boiling water, wash hands frequently, and prevent pests and diseases from burrowing into the mouth; Mosquito repellent and rat catch......

There were about twenty sentences in total, and he read it and handed it to Jia Sima. But there are still a lot of questions in my mind. After reading it, Na Jia Sima also had questions in his heart.

For example, why do you drink boiled water, and why can you disinfect liquor and alcohol, etc.

"I know you have a lot of questions, so I'll tell you a little bit. Ge Xianren once said that the reason why people get sick is that diseases and insects enter the human body.

You may not know that there are so many worms in that water that you boil the water, and then you die! Especially roundworms, this method is very effective.

Also, if your hands are cut and scratched, you can wipe them with white wine, which is also very effective. Why? It's very simple, people will get drunk if they drink too much wine, and how small the worm is, it will naturally be anesthetized to death by this wine!

And mosquitoes and flies, you know, they fly from dirty things, and naturally there are a lot of pests and diseases, so ......"

He's also making up nonsense. For people at this time, they don't understand what microorganisms you tell them about viruses.

If you want to say that there are pests and diseases, they still believe it.

"All of this was said by the stranger who taught me how to make zinc and steel. Come to think of it, if he hadn't taught me this, how would I have understood? My master, who seemed to be a mortal at the beginning, may be a fairy now......" He talked eloquently, making the two of them unconvinced.

In the end, he said: "Just tell you what I told you, and you will convey it to the people in its original form!"

It is necessary to mobilize all state and county officials, village officials, and li officials to publicize and publicize the sanitation campaign. What is a sanitation campaign? It is the movement to defend our lives......

After my careful consideration, Jia Sima is responsible for this matter! As long as you make achievements, your Sima is the first credit, and Zhang Hucao is also indispensable! I'll give you a test! ”

"The lowly rank must do his best!" Jasma was unusually respectful.

"Especially when you drink a strip, you may not be used to it. This is especially important and must be implemented conscientiously! The county officials and village officials who are not effective in publicizing this work must be dealt with seriously! ”

"Yes!"

……

"Judge Jiang, how about you try this soap?" Wu Yanzhi handed the soap he had made to Jiang Shipeng.

This soap is actually very easy to manufacture.

Soda ash and lime are made into soda ash solution and lime milk by alkali respectively, and causticizing reaction is carried out at 99~101 °C, and the causticizing liquid is clarified and evaporated and concentrated to more than 40% to obtain liquid caustic soda. The concentrate is further boiled and solidified to obtain a solid caustic soda product.

Na 2CO 3+Ca(OH) 2= 2NaOH+CaCO 3↓

This caustic soda is then boiled with animal oil or vegetable oil to make soap.

Also, if you add spices and dyes to it, you can make a soap that has both color and fragrance; If you add some medicine (such as boric acid or carbolic acid) to it, it becomes a medicated soap.

Originally, according to Wu Yanzhi's idea, he didn't want to do this thing. However, after all, he himself is a person from a thousand years later, and it is extremely inconvenient to wash his hands without this thing on weekdays.

Coupled with the hygiene campaign he wanted to promote, it was natural that he had to do something to promote this soap and soap among the upper class society in Xingzhou.

Anyway, now that there is soda ash again, let's make some.

But to be honest, this thing is indeed a high-end material, and ordinary people can't afford it. Wu Yanzhi calculated, this thing is made, and the cost of a piece is five cents, and ordinary people are reluctant to do it.

The main reason is that the cost of soda ash is quite high, and this vegetable oil is actually very expensive, the cheapest tung oil is more than a dozen dollars a bucket, and other vegetable oils are more expensive. Because the price of rice at this time is very expensive, sometimes it costs seventy or eighty wen a bucket.

Even the lard was eaten by the common people. Ordinary vegetable oil should be used to light lamps or sell for money.

Jiang Shipeng looked at the soap: "It's okay now, it looks good!" ”

He has been involved in the development of this soap, and this thing is produced, one is to sell it in Xingzhou, and the other is to send some to Emperor Wu Zetian, as well as the prime ministers and princes of Shendu. Please Baidu "Throw Book Network" Thank you for your support!
