The woman said that the rooster crowed, the scholar said that the morning in Xiangcheng, the Changsha County Governor's Office, was as usual.

In the vicinity of Guansi District, what officials such as Xiangxian Ling and Cheng did after getting up was to ask the attendants to bring a commode and sit on it to close their eyes and recuperate.

And ordinary officials are not so particular, they go to the backyard where they grow vegetables and vegetables, unbuckle their belts, squat in front of the dung pit, yawning, while thinking about the work to be done today, and these feces will be fed directly to the black head at home.

The lowly Luzuo, common people, and businessmen have a narrow courtyard, and it is good to have a place to live, and there is no convenient place at all. They can only open the door of the mat, come to the sewage ditch in the corner of the lilu, pout their buttocks to excrete, and often meet with their neighbors, the two side by side, gossip while pulling, and even share a toilet chip - the nobles of Xianyang have begun to wipe with paper, but they have never even seen what the paper looks like.

And their wives and daughters, dressed in ragged skirts, did not dare to do so in broad daylight, so they had to settle the matter in the commode, take the door out, dump the filth by the ditch, and wash it in the river not far away.

Here, they will meet the servants of the officials' families, and there is a difference between the status of the nobles and Lu Zuo, but their excrement is washed away by the water together, regardless of whether they are high or low.

This is considered a period of high quality, more often, when people in Xiangxian County are in an emergency, they are just looking for a place to excrete on the street, although some women have toilets, but they also like to dump the filth in the bucket on the street.

The whole street is made up of human dung, plus cow and horse urine, which continues unabated, heavy pollution, and mosquitoes and flies buzzing. In the summer, the smell evaporates and becomes even more disgusting, and it is not until the heavy rain has passed that the filth of the street flows into the river.

The streets are cleaner, but the river is polluted, and a few miles downstream from the city, people are doing laundry, washing rice, and even drinking water directly from a scoop. At noon, a group of children stripped off their clothes and jumped into the river to swim, frolicking, but unbeknownst to them, countless tiny insects shook their bodies and burrowed into their skin......

In this way, the Schistosoma eggs complete the cycle, travel from the patient's body to the water, hatch, and then enter the snail to temporarily lodge, grow into cercariae, and float in the water column, waiting for a new target to accept the parasitism.

Xiangxian County has been living like this since the formation of the city in the Spring and Autumn Period, and their coexistence with schistosomiasis will continue for more than 2,000 years.

However, this situation changed at the beginning of the summer of the 35th year of Qin Shi Huang.

The first was the Qin army camp in the upper reaches of Xiangcheng, which was relocated to dozens of miles upstream. Under the persecution of the Marquis of Changnan, the Changsha County Government sent out conscripts to dig deep pits in the streets and alleys of the city, and built buildings on them.

After hearing that it was to repair the toilet, Lu Zuo suddenly laughed and felt unreasonable.

"How can this convenient place be better than my home? There are rain protection tiles and wind-sheltering walls. ”

Although the public toilet has been repaired, but no one uses it, people are lazy animals, can walk one step, never walk ten steps, Xiangcheng's Qianshou still goes his own way, there are even many officials in charge of the people who defecate on the street, and the Changsha county guard does not think it is a big deal......

At the beginning of April, after being frightened by the Marquis of Changnan again, the Changsha County Shou reluctantly issued a decree:

"Those who dump feces on the street and defecate in the open will be fined a shield! Those who wash the dung bucket at the water intake place will be fined one class! ”

With the promulgation of this law, it was posted all over the city, and the entire Xiangcheng was scolded, and the people of Southern Chu muttered that this group of Qin officials had a lot of things, not only heavy taxes and harsh administrations, but also extremely heavy forced labor, and now they even had to take care of their Lazar affairs!

The three local elders found the county guard and stated the inconvenience caused by this decree to the locals, as well as the troubles caused to the local officials by rectifying this trip - Changsha County does not have so many officials and soldiers, and they can see the feces and urine of three or four thousand households in the city!

Changsha County is also bitter in his heart, this is all forced by the Marquis of Changnan, and he also keeps saying that "Xianyang, Jiangling, and Anlu all have this law, and the two battalions of Wuchang and Chuting have also been implemented."

In the end, Heifu once again blocked the mouth of the county guard with the illness of the child, and heard that Changsha officials were scarce, so he enthusiastically sent a team of soldiers to Changsha City to help.

At the beginning of April, the people of Xiangxian County watched in amazement as 500 Qin soldiers wearing red armbands in their right hands drove into the city with great vigour......

……

"Those who defecate in the open will be fined a shield, and say what about you! Stop, don't run! ”

In Xiangcheng, a game of cat and mouse, fart and urine flowed began.

Most of the 500 soldiers were chronic schistosomiasis patients, who were desperate to die in the barracks, but after Chang Nanhou came to Changsha with Chen Wuji, he treated them, although he failed to pull out the root of the disease, but his health was much better, and he was grateful to Heifu.

After hearing that the feces and urine on the streets of Changsha were the cause of the perennial epidemic of water Gu, malaria and other evil diseases, they hated it and were very active in their work.

Five hundred people were dressed up by Heifu, wearing a red armband on his right hand, extremely eye-catching, a team of five people, patrolling the city in batches, caught one and fined one, and if there was no money to pay the fine, they were taken to the military camp in the upper reaches of Xiangshui to work, and it was paid off......

As a result, the behavior of open defecation in Xiangcheng and washing toilets in water sources has been reined in a lot.

But this group of soldiers wearing red armbands were scolded by the people of Changsha County as the "Red Arrow Army", and the name of Heifu "Public Toilet General" also flowed into the people, and his reputation really stinked.

The leaders of the later generations who are engaged in the creation of culture and creativity, who are not scolded by the county people?

"It's really stupid, I don't know that Chang Nanhou did this for their good."

Ziying shook his head, feeling worthless for Heifu, as the commander of the Southern Expedition, he just had to fight, but Heifu passed by Changsha County, but he was willing to do this for the sake of the local Qiantou, which was completely unnecessary.

"If Changsha has been an epidemic area for a long time, it will not be good for the army that travels from the south to the north."

Heifu smiled and gave a reasonable explanation: "Nanjun and Changsha are separated by a river, with a cloth of water, similar language, similar customs, and Changsha people are also my township party, how can I not save them when I die." ”

In later generations, he is really a man of the two lakes, he loves this land deeply, even if he doesn't save the group of adults who don't know what to do, at least, he has to save the children.

And Hefu has always thought.

"A civilized army, a mighty army, can bring not only death and thorns, but also civilization and progress......"

……

Having said that, the situation is still not optimistic, even if it is rectified, at night, there are still people pouring feces on the streets of Xiangcheng to vent their dissatisfaction with the government.

In the countryside outside the city, there are a few public toilets that are not cared for. Locals still apply fresh manure directly to paddy fields without composting, and then step around the fields barefoot. As for the government's advocacy of drinking well water, or storing river water for three days and then boiling it for drinking, no one has implemented it at all.

"Don't they know that compost and manure can make the land more productive?"

In mid-April, Li Cang returned to the barracks to report on the current situation, and even the children of the overseer army raised confused questions.

"I've asked some old farmers about it, and they don't care."

Li Cang explained: "The land south of the Yangtze River in Changsha is different from Guanzhong and Nanjun, the land is vast and sparsely populated, with rice, soup and fish, vegetables and fruits full of mountains, and clams and rivers, so the locals do not wait for Jia. Different from the intensive cultivation of the Central Plains, in Changsha, even if the fire is cultivated and the water is raked, the coarse planting and the harvest are rough, anyway, there are two crops a year, and there is no famine......

This is the reason why temperate civilizations have endured and flourished, and although the tropics have a large population, there are very few advanced civilizations. Without him, there are many resources, and you don't have to work hard day and night to be able to eat and wear, who is willing to work hard and figure out how to increase the grain production in the field!

Laziness, this is the eternal nature of human beings, who can sit and never stand, and can lie down and never sit. Thanks to the dense population of the Central Plains, the impermanence of drought and floods, and the distinct seasons, the people's livelihood is difficult, and they must want to break their heads to survive, which has created the hard-working character of the nation, and the Chinese can laugh at the laziness of people in Southeast Asia and Africa after two thousand years.

This is the reason why compost, which is very popular in Nanjun and Guanzhong, is not imitated in Changsha. Therefore, similar to the city, in the countryside, schistosomiasis can also complete the life cycle unimpeded, because farmers plant paddy fields and go down to the river to fish, the infection rate is higher than that in the city, and edema disease with large abdomen and thin limbs can be seen everywhere.

"You still have to punish the law harshly and force the head of the Qiantou to pile up the manure of each family."

Ziying suggested this, and when he thought that the water he was soaking up in the Miluo River was actually the stinky water from the dung buckets of a farmer in the upper reaches, he was so angry that he felt that he must take care of this group of Southern Chu Qiantou.

But Heifu shook his head:

"It is still possible to send soldiers to inspect and rectify in the city, after all, the population is concentrated and it is convenient to manage, but it is impossible to live in the townships where the household registration is scattered."

In this invisible war, Heifu has considered that the eradication of schistosomiasis in the future depends on the elimination of snails, which requires the mobilization of the whole people, but at present, he has neither the means of later generations, nor enough manpower, so it is no fun to exterminate snails, and rash implementation will increase infection.

Therefore, the only way to prevent the infection is to cut off the channels of infection, and people in the foci of the epidemic will pollute the water source by washing the toilet, defecating in the open, applying fresh manure and grazing cattle by the river, and control people's buttocks, and mix the manure with urine and compost it for harmless treatment, which can greatly reduce the infection rate. Drinking boiled water can not eliminate the disease, but it can increase the life expectancy of the local people by one or two years.

But he overlooked one thing, one of the most important things!

Heifu had seen a movie in his previous life.

It says that there is only one disease in this world: the disease of poverty!

But there is another disease, according to Heff, which is not only more terrible than the disease of poverty, but also more stubborn than schistosomiasis, which haunts the world and is passed down from generation to generation.

Heifu muttered to himself, "The name of this disease is 'ignorance'!" ”

……

Ignorance is the feces and lingering mosquitoes and flies on the streets of Xiangxian County, but passers-by are accustomed to turning a blind eye.

Ignorance is knowing that he is suffering from illness and holding up his swollen belly, but he is indifferent to the child drinking dirty water.

Ignorance is that when Heifu sent people to help clean up the city and save their lives, he also bit Lu Dongbin and didn't know the hearts of good people.

Hefu can find a cure for malaria, a cure for schistosomiasis, but a cure for ignorance, is there a cure?

In the camp, Chen Wuyi proposed to make the prescription for the treatment of water Gu and malaria public so that the people of Changsha would know, and Heifu nodded in agreement, but shook his head again and said something inexplicable to him.

"Studying medicine can't save the Chinese."

Ziying viciously suggested that he should write to the court, increase the punishment, and follow the law of Yin Shang: those who abandon the ashes of the Tao will cut off their hands. Use the method of blackening words on the ass to crack down on those who refuse to change their ways.

Hefu praised his whimsy, but added: "Just by the government to come forward and punish the law strictly, can it be done once and for all?" ”

The harsh punishment is a fierce medicine, defecating and defecating everywhere, washing the commode in the water source and cutting off the hands, and swimming in the river and cutting off the feet, which will indeed scare off many people.

But this cannot win their gratitude, and the people only have resentment in their hearts, and I cut off your hands and feet for your good, who can understand? And once the government loses its power, they will happily overthrow the evil law, and what was done in the past will still be the same in the future.

Neither herbs nor punishment can cure the disease of ignorance.

So, is there a more effective medicine that can cure for a long time?

Some!

While everyone in the camp was talking, Heifu stood up and walked silently to the desk.

As early as thousands of years ago, the Chinese ancestors had already invented it.

It's called text.

However, the original writing was monopolized by aristocratic wizards with a population of 1/10,000, and it was not easily displayed with knives carved on precious tortoise shells and bronze objects.

It was not until later that bamboo slips appeared, and the group of scholars also came into being, and in the continuous exchange, their ideas began to explode, and then there were hundreds of schools of thought, but knowledge was only spread among the elite of one percent of the population.

More than ten years ago, the officials of the Qin State simplified the text, it became a smooth stroke, Meng Tian also made a better pen, the time required to write an article is several times faster than in the past, the Qin Dynasty's law order book system can be established, after all, the law is at stake, under the tireless preaching of the Qin officials, at least one tenth of the people, a rough understanding of the law.

And because of the arrival of Heifu, paper also began to become popular, and four years ago, he made up the last piece of the puzzle: block printing.

Words, pen and ink, paper, printing, and medicinal materials are all in place, and then, all it takes is a doctor who can think deeply to mix these materials to make a medicine that warms and nourishes the blood, it may not take effect immediately, but perseverance, you can nourish a healthy body......

Studying medicine can't save the people of ignorance, but knowledge can!

No one is born knowing, and no one is born intelligent.

Our ancestors were ignorant and ignorant, like the head of Qianshou in Xiangxian County, who lived a life that had not changed for thousands of years: riddled with diseases, precarious, and an average life expectancy of only more than 30.

But in my generation, even in the countryside, we were told from an early age to wash our hands before eating, to get sick from the mouth, and not to drink raw water.

Of course, these things didn't come out of thin air, so how did they know about it? When did these hygiene habits come into being?

It was an era of material poverty, but full of idealism, there was a group of doctors, not even doctors, who, under the call of the party, went deep into remote villages, with *** quotations on their left hand and "Barefoot Doctor's Handbook" on their right.

They flipped through the easy-to-understand words of the book, told the peasants some of the common sense of hygiene that modern people take for granted, reversed bad habits that had lasted for thousands of years, and also in the south, almost eradicated schistosomiasis, which had ravaged for dozens of centuries, and sent away the plague gods......

In the Qin Dynasty, this matter may take several generations or even hundreds of years.

This matter may not be able to see any results in the near future, and Yu Heifu will not benefit from half of it.

But someone has to write this prescription.

"Then I'll start with me, starting today!"

Heifu spread out the paper, picked up the pen, and tapped on the case, so that the people in the account stopped the dispute.

"No blame brother."

Heifu smiled: "I want to ask you to help me write this book!" ”
