As soon as Xu Hao returned to Beijing, he heard that there was a large-scale cholera outbreak in Annan last year, killing no less than 100,000 people.

He also has a son who is the lord of Annan. Fortunately, he did not receive bad news. The mother and son should be safe. As for how many people in Annan died, what is the most important thing for you?

As early as the beginning of his illness, the Prince Mu Mansion in Yunnan had ordered the border blockade, and some officials stationed in Nan'an also hurriedly returned.

The Fujian Guangdong Navy Admiral's Office also issued a warning that merchants were not allowed to go deep into Annan. Anyone who came back from attacking Annan must stay on the border between Hainan and Yunnan for one year to prevent the spread of the plague into the inland.

In ancient times, there were extremely important plagues and quite perfect laws, so Xu Hao didn't need to worry about it.

Zhu Gaochi also attached great importance to this. He ordered Liu Chun, a famous doctor who was very famous, to find a way to find a treatment prescription. The imperial doctors of the Imperial Hospital proposed to get a few cholera patients from Annan, but Liu Chun was worried that cholera would break out in Jinling, so he asked the imperial doctors to create a cholera model.

Xu Hao did not expect that there was such an advanced scientific research method. Unfortunately, cholera is a strongly contagious disease that cannot be eradicated, and humans are the only susceptible to cholera bacteria.

In the Imperial Hospital, Xu Hao said: "The way to prevent cholera is very simple, but it is not simple, that is, pay attention to hygiene. Sanitation is divided into personal hygiene and public hygiene, and I don't need to say much about this. In particular, we should pay attention to the cleanliness of water sources, which is the biggest way to the outbreak of cholera. As the saying goes, diseases come from the mouth, eating raw sea food and unwashed vegetables will also be infected. Do not drink cold water directly. Therefore, this involves public health. It is necessary to work together at all levels of the government, inside and outside the government, and local governments at all levels."

The imperial doctors nodded frequently and agreed. The facts have long proved that even if Mr. Xu farts, he can still understand the past and present!

No matter what, Xu Hao proposed the concept of public health, and then it will be gradually improved by officials.

But Jin Da went to Sichuan with the prefect. Unexpectedly, in Shanxi, a villager Liu Zijin gathered a group to stir up trouble, occupied the post station, and defeated the Datong defenders, and the group disappeared.

The imperial court appointed the general of the army Zhang Fu as the general officer, Cai Fu and Mu Xi as the deputy general, and led the Shenji camp to fight for the expedition and suppression. Two months later, 135 people including Liu Zijin were escorted to the capital. Zhu Gaochi issued an order to behead the leader and show the public the rest, and sent the Han Wangzhou to assassinate the army.

He lost the news about Jin Da for a moment. Wan Ying was still practicing medicine in the clinic. Most of the people who seek medical treatment only heard about his reputation, but did not know the person. Everyone who came here was Mr. Jin and Kim Kung-gun shouted.

Those who knew Jin Da saw that Wan Ying used similar medicines as before, and since they could cure the disease, they regarded Wan Ying as Jin Da.

After all, several neighbors knew that Jin Da was gone, but Wu San warned him a few times. Later, Wan Ying simply moved to the area of ​​the Water Dragon Palace in Xiaodongmen.

Some officials who were informed were very suspicious and stood at the door and talked: "Didn't Mr. Jin go to Sichuan with his former prefect? ​​Why are they still in Zhenjiang?"

Someone heard this and went into the house to ask Wan Ying. Wan Ying was worried that she would show her flaws and said, "That's right. Originally, the lord had to let me go with me. I didn't want to go to Sichuan, so I recommended a friend named Wan and let him go. So everyone misunderstood that I was leaving."

Because there is no interest in it, naturally no one will ask the bottom line while idle, and everyone will soon believe it.

Wan Ying quickly made some money, but unfortunately got cholera. It turned out that he treated a merchant who had returned from Annan. The other party invited him to dinner. Although the person was isolated for one year, the seafood that entertained him carried bacteria.

As the saying goes, Doctor Lu doesn’t treat himself. Although Wan Ying prescribed a lot of medicine for himself, in ancient times, when the mortality rate was as high as more than 40%, his physical condition was weak and he did not dare to drink water. He died of dehydration and high fever due to his fatigue and high fever.

After he died, the Imperial Hospital, with Xu Hao's tips and help, was introduced to treat cholera in the world. The roughly means drinking more water with sucrose and lemon, and replenishing water and salt at any time. Although there is no science from later generations, such as replenishing electrolytes, the mortality rate can be controlled within less than 10%.

Of course, that means that if conditions permit, most people who have cholera will develop immunity, and re-infection is rare. If public health is done well, there will be enough medical staff to rescue them, and they can eliminate contaminated water sources in a timely manner, and be careful not to let the patient's feces contaminate the water. Cholera can be completely controlled and the mortality rate will be greatly reduced, which has long been less than one percent in later generations.

After Wan Ying died, unfortunately Wu San also injured people because of a fight and ran away overnight. Several hired servants were not close to him, so they divided the money and handed a report to Zhenjiang County.

No one knows where Wanying is from. When he came, Jinda didn't want to reveal his family background. The two had an agreement not to say their hometown.

The magistrate sighed and said that a good man would not live long. He bought him a coffin and buried him in a place with good feng shui outside the city. A line of words was engraved on the tombstone: "The Tomb of the Famous Doctor Mr. Jin", which was kept for his relatives to recognize each other.

Jin Da's old servant followed Xu Hao back to Beijing to report that Jin Da wanted to surprise his wives and concubines, so the old servant didn't know that he had gone to Sichuan and returned to Zhenjiang, and learned that the young master was actually dead.

The old servant came to his senses and hurriedly asked the neighbor: "My young master and Mr. Wan are with him. The young master is dead. He should rush back to report the news. Where are the people now?"

The neighbor said, "The surname of Wan was recommended by your young master. I went to Sichuan with the former prefect. He walked in front and died behind him. He was thousands of miles apart. How could I know that my friend died of illness? Not to mention rushing back to report to you."

The old servant was old and a little confused. He believed it now and found the tombstone outside the city and cried bitterly.

Because he was the only one, it was not convenient to open the coffin and send it back to Jinling, so he had to hurry back to Beijing to report his demise.

Now the relatives and friends of the Jin family were confused. Unexpectedly, they really fulfilled the fate that Jin Da calculated when he was alive. He couldn't overcome the hurdle of twenty-nine years old. Everyone sighed, and Xu Hao, the only person who knew about it, took his whole family to Beidaihe for the summer vacation.

The Jin family's divination technique is famous all over the world, so everyone believes it deeply. Jin Da's wife and concubine were heartbroken and cried bitterly and put on mourning clothes to set up a mourning hall. They cried for three consecutive days. Everyone who came to pay their respects was sad when they heard about it.

On the fifth day, Luo and Mo were still crying, but only the maid Bi Lian of the room still had a sad look on her face, but she stopped crying.

Bi Lian advised: "A person cannot be resurrected when he dies, and crying is useless and will hurt his body. The two grandmas should take care of themselves and take care of their funerals for the young master, so that they will not make people cry."

Mrs. Luo said angrily: "You have a way out, so naturally you are not sad. But we have stopped here for the rest of our lives. Can we not cry? "

Mo also said: "I have been a widow at a young age and have no savings at home. What should I do in the future?"

Bilian said: "We have so many colleagues and old friends in our family. If you only say the Xu family, you can't ignore it. Grandma, don't worry."

"What do you know?" Mo said angrily, "When someone leaves, the tea is cold. Besides, there is a widow in our family. Who is the only one who is willing to help you? You have nothing to worry about and leave as long as you want, so you don't have to say something nice."

Bilian didn't want to have a kind heart, so she had a boring conversation and smiled bitterly and didn't dare to say anything.

The two girls cried for several days, and there was no need to persuade them. Naturally, they stopped crying, but they didn't think about food and food every day, and kept sighing.

What Bi Lian said was to ask the two grandmas to make a decision quickly. The first thing was to send people to Zhenjiang to take Jinda's coffin to Jinling or send it to his hometown for burial.

The second is to persuade grandma to make a living. Jin Zhong is honest and has not left much property. He can use the existing money or purchase farms or run shops. Only in this way can he keep the integrity of the Jin family well.

However, when Luo's words "There is a way out", Bi Lian's mouth was blocked, and it was difficult to speak again in the future.

The family was also confused. At first, they thought that the two wives were too sad and had no intention of discussing their funeral. Who would have thought that after another month, they would never mention the word "pretending to be a mourning person"!

After all, Bi Lian couldn't bear it anymore and asked, "The young master's bones are far away in a foreign land. I wonder when grandma will send someone to bring them back?"

Luo said angrily, "I am a big wife, and I don't want you to speak up for the family? As a husband, you must inform the local government and gentry with great fanfare and hire official boats to transport them. It will cost at least a thousand taels of silver. Now that the family has organized two funerals in a row, how can there be any money? According to my words, I have to send a few people to secretly go there and burn them on the spot and bring them to their hometown to bury them in their ancestral graves. Alas, why do we have to do a good job of being a good person? Save money and live a life."

Mo said, "I don't have to go if I want to say that. My husband has gained a reputation in Zhenjiang and everyone admires it. Why not stay there and wait until the child is grown up. At worst, we can go and worship together during the holidays."

Bi Lian was stunned. No matter how poor the Jin family was, it was not less than a few thousand taels of silver? Not to mention the gifts received by the husband's death, when the master died, the palace rewarded thousands of gold. Even if it was all done, you two have a lot of private money hidden on weekdays, so you can't spend some money?

Bilian felt uneasy and wanted to blame her for her righteousness, for fear of angering them, so she colluded to drive her out. Judging from the selfishness they have exposed at present, they may not make many mistakes in the future. If she leaves herself, she will not even have anyone to advise her.

She thought for a long time at night, and the next day she arrived at the room, and said seriously: "I discussed with the housekeeper yesterday, so I don't have to hire a single official boat for Fu Zhu. Even if the local government is alarmed, I don't have to hold a drink and socialize as a master. Some relatives and friends' families have boats, and they can only take a boat for a boat, which costs only a hundred taels of silver in total.

My little sister has about fifty taels of silver in her hand. I wonder if the two grandmas can make up half of it? If I can’t make up, I still have a few silk clothes that I can’t wear for three years. Why not sell it for me? It’s better to sell it for me. The young master dares to take it on my own, but I don’t have to rely on the aunt and second mother to make the decision.”

These words made Luo and Mo’s faces flushed. It turned out that most of the money was regarded as private money by them. They were originally going to hide it by their side so that they could take it to someone else’s house to supplement their husbands’ back. Everyone was about to leave, who would care about the decency of the Jin family?

Now that Bi Lian is speaking righteously, he naturally dare not refuse to say no. The two girls said in disappointment: "Since you think so thoughtfully, how can you not have a hundred and eighty taels? You don't have to spend money, keep it yourself." (To be continued...)
