It's time to get up at dawn and start dancing when you smell the chicken.

Just as dawn was dawn, Li Chao got up, kissed Du Shiniang goodbye, washed up, changed clothes and went out. When he came to the yard, he found a group of little radish heads at home, following his father excitedly practicing guns.

Li Chao also asked the children to run, squat and practice guns with them. But every time, they were reluctant and shouted pain and tired.

"You're late!"

When the father saw Li Chao coming in wearing a training suit, he stopped his movements and said to him with a smile.

"These guys are still the closest to their grandfather."

"You are too strict." Dad asked a few little guys to rest and let them move freely. Boss Li Jing took the initiative to send a towel to his grandfather, which made his father laugh and reached out to rub the short hair on his head.

"The child is indeed a different generation of relatives, and Li Yue is not so close to me." The father was not very satisfied with the youngest son. In his opinion, Li Yue was different from Li Chao, and he was willful and naughty, especially because of his wife Qi Niang's favor, he became a little lawless. Sometimes he got angry and beaten up, but Qi Niang had to argue with him.

"It's still Jing'er and the others who are obedient." The father sighed at the group of grandchildren who were chasing each other excitedly.

My father was just arrived in Hanjing yesterday. The family came from Liaoxi and walked on the road for more than a month. My father was already used to the life of the territory castle in Yanbei. Looking at a deserted place, the castle slowly stood up and the village was built, seeing the leaders settled down, seeing the merchants open in the castle, and watching the increasingly lively territorial markets, my father liked it more and more.

However, the eldest daughter was about to get married, so my father gave up everything in the territory and rushed back to Hanjing.

"Dad, your complexion has changed better, and it seems like you are a few years younger." Li Chao exclaimed.

"In Yanbei, the mountains and rivers are beautiful, it's really good." The father smiled. He felt that he had indeed rejuvenated his second spring, and his life was getting better and better, except that his younger son was not very obedient.

"Yuelang is still young. Actually, Yuelang is the old man of Qi Niang, so he must be more pampered. If you are willing to let him go, leave him in Hanjing and I will discipline him personally. I will make him a good man in two or three years."

The father looked at Li Jing and the others, "I believe that Jing'er is young, but you have already taught him very well. Although he is a little afraid of you, he is much more sensible than Yue'er." He sighed. He was willing to leave his younger son to Li Chao for teaching. The elder brother is like his father. It is definitely good for Li Chao to come to teach, but he is afraid that Qi Niang will not agree.

The eldest daughter of Qi Niang is about to get married, and the younger son is only three years old, so it is normal for him to be a child in old age.

"Will you stay in the capital next year?" asked the father.

Li Chao stole a horse and then stole it seriously.

"Well, I will definitely stay in Beijing next year."

"Didn't it mean that Your Majesty has accepted your words?"

"Resigning to the emperor is resigning to the emperor, but I still can't leave the capital next year." Li Chao replied with a smile. The apparent reason was of course that Li Chao had to stay in Beijing to be responsible for the imperial examination reform, but in fact, Li Shimin is unwilling to leave Beijing now.

Why not let it go is not a complicated issue. Of course, you still need to observe.

"The capital is also very good. If you have time, you can get along with Jing'er and the others, and it is also important to educate your children."

Li Chao nodded, "Yes, it's really good to spend more time with his wives, concubines, and children and enjoy family happiness."

"Dad, I will pick up acne for the children at home tomorrow, and then let Yueer take acne together." Li Chao suddenly remembered that there was another important thing.

When he heard Li Chao mention this, his father asked hesitantly, "Is it really useful to take acne?"

To receive acne, that is, to receive cowpox.

This is a way to prevent smallpox proposed by Li Chao.

Smallpox is a very serious disease. As early as the Jin Dynasty, the famous pharmacist Ge Hong recorded in "Emergency Prescriptions for Elbows", "When he was sick, he still had sores, head, face and body. After a moment, he was like a fire sore, and he was all carrying **. He was born as a result of the knot. If he was not treated immediately, he died. If he was not treated badly, the sores were scarred and purple and black, and the prescription was eliminated after a while. This vicious qi was vicious."

This is an early record, but smallpox has always been an acute infectious disease that has been accompanied by humans.

In later generations, smallpox was long extinct.

But in the Tang Dynasty, smallpox was an infectious disease that discolored people. It was terrible because the mortality rate of this infectious disease was extremely high, reaching more than 30%.

And it is extremely contagious.

If you are lucky, you will become a marijuana seed after you survive.

This disease first develops high fever, red papules all over the body, then turns into herpes, and finally becomes pustules. If it gets cured, it will form scabs in about ten days, and the scabs will leave scars after they are removed, which will be pockmarked.

Smallpox is caused by infection with poxvirus and there is no cure.

This disease not only leaves pockmarks, but also has a very high mortality and infection rate.

Because smallpox can be contagious mainly through inhalation or direct contact of droplets, it was more contagious in ancient times when prevention and control methods were insufficient.

Children are particularly difficult to resist smallpox.

Children have extremely high mortality rates after smallpox.

However, smallpox also has a characteristic, that is, after one has healed, it will never get it again and will be immune for life.

Smallpox has always been an incurable disease, but Li Chao had heard before that before the smallpox vaccine came out, someone used vaccination to prevent smallpox.

Vaccinia is also a kind of acne. Milkers can easily get vaccinia. Vaccinia will also cause chickenpox on their hands and even pus. But compared to smallpox, vaccinia is just a light virus that will not cause death and will not even have a great impact on people.

Later, a doctor asked someone to deliberately inoculate cowpox, and when the cowpox is cured, he would never get infected with the smallpox again. This method can be said to be a special method to prevent smallpox for a long time, saving countless lives.

Li Chao started looking for someone to experiment with this method a long time ago.

It was just that it was tested on animals at first, but later it slowly turned to humans.

After all, this is a method that no one has ever heard of, and it also treats smallpox, an incurable disease.

Therefore, it can be said that this experiment was also carefully and continuously observed.

It was not until now that after several years of experimental observation that Li Chao decided to take acne to his children. The child is so young, has weak resistance and is prone to acne. Once it occurs, the mortality rate of up to 30% is extremely worrying.

Although not everyone will get acne, the probability of acne is still very high, and it doesn't happen by itself, but it is also easy to be infected. Actively collecting vowel, and after being vowel, you can be immune to smallpox virus for life without fear of infection. Li Chao felt it was necessary to let his children take it. He even planned to let adults at home take it. After all, smallpox is not only children, and it is possible to get it even in his twenties and thirties.
