As evening approached, the sky gradually darkened. Although it was spring, the cold night wind still had a hint of chill.

The noisy sounds in the industrial park gradually became quieter. The workers finished their work for the day and prepared to go home for dinner.

Chen Ergou kept working, but there was a silly smile on his honest face. The workers next to him couldn't help but make fun of him when they saw this.

"Oh my, oh my~ Ergou looks so happy, I guess he's going to meet your girl Lan'er again later?"

"Hey, don't spread rumors everywhere. Lan'er hasn't agreed to me yet. Don't ruin her reputation."

When mentioning his sweetheart, Chen Ergou's face turned red, but he still explained the truth frankly, not wanting Lan'er to suffer any rumors because of it.

He likes Lan'er, but he won't use any despicable means to force her. He hopes to gain the recognition of his sweetheart with his own ability.

Seeing that Chen Ergou looked unhappy, the worker stopped talking and changed the subject.

"Ergou, I want to remind you not to forget the hygiene seminar tonight."

"What conference? How come I don't know about it?"

"...Ergou, your heart is really tied to Miss Lan'er..."

Seeing the confusion on Chen Ergou's face, the worker twitched his lips, then thought of something and laughed happily again.

Hey, you know what, this guy's silly look when he's in love is exactly the same as when he was chasing his wife.

The bright moon hangs high in the dark night, and the light it casts is so bright that there is no need for candlelight.

In the central square of the park, workers were bustling around sitting on the benches they brought with them, each with a look of curiosity on their face. They looked up at the empty platform and talked among themselves.

"What kind of meeting is this? I'm so hungry that my stomach is growling, and the dinner my mom made at home is getting cold."

"I heard that the students from the Academy Medical School are here to hold a meeting with us!"

"Are you going to see us? With so many people here, the waiting list won't be until tomorrow..."

“…”

As everyone waited eagerly, several students in blue clothes finally walked slowly onto the stage.

Even when facing thousands of people, they remained calm and prepared in their hearts. This was their first health education seminar and they had to make it a great success.

After Qian Duo and others put the shelves, basins, soaps and other things in place, Bai Ying looked around at the workers below, his face solemn, and spoke in a loud voice.

"I am Bai Ying, a student at the Academy's Medical School. I'm here today to educate you about hygiene."

"What is hygiene? Keep clean, don't drink raw water, wash your hands frequently..."

"...bad hygiene habits often lead to unbearable abdominal pain, which is caused by bacteria and parasites..."

The speech was well-reasoned and powerful, which gradually attracted the people who had originally disdainful of it, and the awareness of hygiene began to sprout in their hearts.

The reasons for the previously inexplicable abdominal pain were now known. Some workers suddenly realized the truth and excitedly told others about their experiences.

"No wonder... I was wondering why my stomach aches so badly every time I drink raw water. Turns out there are bugs..."

"My two little brats just love to drink cold water and don't even wash their hands when they eat. I'm going to teach them a lesson when I get home!"

"My mother has always told me since I was a child that eating dirty food won't make me sick. But that's clearly a fallacy. This girl is right. Diseases come from the mouth..."

When it comes to physical health, no one dares to be careless. These days, not only is it difficult to see a doctor, but it is also difficult to cure diseases. The best solution is not to get sick and to prevent it in advance.

After explaining the hygiene precautions, Bai Ying picked up a piece of light yellow soap and began to demonstrate the "Seven-Step Hand Washing Method".

The workers below were studying seriously while thinking about going to the supply and marketing cooperative to buy a bar of soap tomorrow. It wouldn't cost much anyway, and money was not as important as life.

So, the next day, in the supply and marketing cooperative.

The saleswoman looked at the crowd of customers and fell into deep thought. Could it be that her efforts moved God?

As health education seminars were held one after another and workers spread the word, the people of Xianyang finally realized the importance of maintaining cleanliness and hygiene.

Soap quickly became popular in Xianyang City, and it was only a matter of time before it spread to counties across the country. As a result, the health and medical conditions in the Qin Dynasty improved imperceptibly.

The large number of orders forced the soap factory to work overtime. The business school students were very excited, and the anxiety they had felt for many days disappeared.

At the same time, Chu Yuening in Zhangtai Palace also received good news.

After reading the secret letter, she clapped her hands happily and came to Ying Zheng to share her joy with him.

"A Zheng, look, the soap is finally sold."

"Why does Yue Ning take this matter so seriously?"

Ying Zheng lowered his eyes and stared at his wife's slightly pregnant belly. He gently embraced her with his big hand and let her sit on his lap. Then he asked slowly.

The establishment of a new factory is not uncommon, but Yue Ning has never reacted so violently before. Could there be another purpose?

Glancing sideways at the thoughtful look on the man's brow, Chu Yuening couldn't help but admire his sharp intuition. She sat upright, and a sound like the gurgling of running water rang out.

"In fact, many diseases are caused by unhygienic habits. In the past, people were hungry and had no choice. But now that they have enough food and clothing, they need to pay more attention to hygiene."

"Most epidemics are caused by drinking unclean water or eating animals that carry bacteria."

"Some highly contagious diseases are even more terrifying than war, silently tormenting people to death..."

After saying this, Chu Yuening frowned slightly, and a hint of nostalgia and sorrow appeared in her calm and clear eyes.

Once upon a time, an epidemic took away many people, including the kind-hearted village elders, familiar classmates, and countless unsung heroes...

Even in modern times when medical care is advanced, it is impossible to eliminate epidemics in a short period of time, let alone in ancient times when medical care was backward?

Even if she has a golden finger, she cannot completely eliminate it, and can only take some preventive measures in advance.

"Yuening, don't worry too much. Daqin will get better and better."

"I will instruct the counties to arrange for health education."

Ying Zheng's eyes narrowed and his expression became serious. How could he not know how terrible the epidemic was?

Each epidemic would destroy one or even several cities, and tens of thousands of people died in desperate waiting.

Although it may seem a bit unfounded at the moment, it is always better to be prepared for any eventuality. Even if it can alleviate some of the illnesses of the people of Qin, it will be a good deed.

The man's steady and powerful voice carried a strong sense of security. Chu Yuening raised her eyes, and the calm face was reflected in her pupils as black as ink jade.

She suddenly smiled, held his handsome face, and responded gently.

"Okay, I believe A Zheng."

The fact that the epidemic was prevented in advance just because of a few words from her showed not only A Zheng's trust in her, but also A Zheng's kindness towards the people of Daqin.

How many rulers in history cared about the lives and safety of the common people?

Those who treat the people like grass will surely suffer the consequences; on the contrary, those who treat the people like treasures will be blessed for generations to come.
