Duan heard that the crown prince could not come back when he was giving birth, and he didn't know whether it was a regret or a sigh of relief. Duan always respected the crown prince who was superior to his admiration. This was not only because the crown prince's status was already high, but also because he was born to know and understand everything, like a sage, god and Buddha, but it was incompatible with ordinary people.

Seeing that Duan did not show any inappropriate expression, Zhou Hou secretly praised in his heart: It seems that this Crown Princess is still a person who is very sensible.

Zhou Hou and Zhang Hou are also wise.

Both of these queens are from small families. They are afraid of being in detail. The same class makes them have common habits in expressing etiquette, so the second queen sent someone to send pastries and jewelry to Duan's mother and sister, which is considered a disguised apologies.

Duan was already used to the ups and downs of his daughter's choice of concubines, but she felt a little embarrassed when she received the reward, so she quickly wrote a thank-you note. After Zhou Dynasty, she issued an imperial edict, asking Duan not to be too polite, but just a common exchange between her in-laws. Seeing that the Tian family did not bully others, Duan's parents were completely relieved of their daughter's life in the palace.

In fact, Duan's life in the palace was better than his parents thought.

Not only Queen Zhou and Queen Zhang took care of him, but King Ding, King Yong also had to serve his sister-in-law. Princess Kunxing, who had already married, often returned to the palace to visit his sister-in-law, talked with Duan, and talked about interesting things outside the palace.

On that day, the two sat in the garden pavilion, watching the autumn flowers bloom, eating chrysanthemum cakes, and drinking honey water, which was very comfortable. The topic was unconsciously attracted to the crown prince, and it was Duan who wanted to learn more about his husband through Kunxing.

"Actually, I don't mind that the emperor's brother didn't come back when he got married." Kunxing said: "The emperor's father said he was born to save the Ming Dynasty, and his sister's marriage had nothing to do with the Ming Dynasty."

"You are always the princess of the Ming Dynasty," Duan said with a smile, "but I think he can't even come back from Yuanzi's birth, so he must be unable to leave there."

"This is true." Kun Xing said, "The emperor's brother is cold on the outside and warm on the inside. He values ​​family affection the most, but he just can't tell from his face."

This was the first time Duan heard someone say this about the crown prince, and his face looked surprised: "The Empress also said that he was born in the 'spring cold' season, and he was covered in coldness."

"The emperor's father and mother are arrogant. They eat the two little ones who act coquettishly and behave like a good person, so they think the emperor's brother is a cold person." Kun Xing said: "In fact, the emperor's brother always starts with big things and has warmth in the details. For example, the young sister's marriage, I'm afraid the emperor's father is not as worried as he does."

Duan knew that Kunxing's son-in-law Fu Mei was chosen by Zhu Cilang himself, and he also hit the Silijian for choosing the son-in-law, which is indeed rare in the national dynasty.

"And," Kunxing lowered his voice, "The emperor has changed my mother-in-law to me."

"Oh? I haven't heard of this." Duan was a little surprised.

"I changed to someone who is old, deaf and has difficulty in legs and feet..." Kunxing said as he chuckled: "Now I will keep her in a different yard. I will give her a care for her for the elderly and see her off, and she will not care about me."

Duan also smiled, but she felt more sympathy for her sister-in-law.

The name of the Princess of the Ming Dynasty sounds beautiful, but it is rare to see those who truly live a happy life. In addition to choosing a princess, there are female officials behind the scenes. These female officials control ethics. As for when the princess meets the princess and how long it takes to meet, it depends on whether the princess has enough money.

Zhu Cixuan had no choice but to do anything about this kind of bad policy. Moreover, it was too late to wait for his sister to enter the palace to cry, so he simply asked to choose a female official who could not control Kunxing. It was just a matter of meeting the scene.

"This is done very carefully." Duan echoed.

"The emperor's brother also wrote a letter to the prince-consort, praising his excellent calligraphy and painting, which would definitely be passed down to the world, which made the prince-consort so excited that he couldn't sleep for days and nights." Kunxing covered his mouth and smiled.

"What position has the prince consort been granted now?" Duan asked.

"Now I am a proofreader in the museum." Kun Xing said.

"What grade is that?" Duan said.

"Museums and libraries are not under the jurisdiction of the Ministry of Personnel, and they are not of grade. The salary is taken by the sixth-rank civil servant." Kunxing finished speaking and said, "Actually, he is not very interested in being an official. He can see so many treasures every day, and he is happy all day long."

"That's good." Duan said with a smile: "As long as life is comfortable, it is better than anything else."

"That was the case when the country had something to do, and the adults ordered him to read military books and practice martial arts, and he was frowning all day long. Now that the country is peaceful, there is no need to do these troublesome and tiring homework." Kunxing comforted Duan and said, "When the four sides are peaceful, the emperor will be able to come back to Ansheng to read and write. In fact, the emperor is also a person who likes quietness, and his calligraphy is very good, and he is not willing to run around."

"Loyalty to the emperor and serving the father, and running around and working hard is also the duty of a son." Duan gently stroked his stomach, suddenly frowned and trembled, and moved his body gently.

"Have you moved again?" Kun Xing asked excitedly.

"Well." Duan said: "The days have been much better. I used to punch and kick, as if I had a huge grudge against me."

"What do you say?" Kunxing asked again.

"The doctor said it's normal." Duan said, "It's a shame, because I'm so tired that General Yu and the others have specially found dozens of pregnant women near Jingji, counting this one over the course of the day."

In order to determine the absolute safety of the Crown Princess during pregnancy and eliminate hidden dangers, the Obstetrics and Gynecology Department of Xinglin University specially found more than 30 pregnant women who were specially kept in the college, and they had to eat and do the same food and activities as the Crown Princess, and also recorded the fetal movements of the heartbeat and measured the body temperature.

Most of these women have had one child, so they know how to cooperate and are more happy to take care of their babies here and reduce the burden on their families.

After obtaining these more than thirty samples, and comparing them with the progress of the Crown Princess, you can predict the general development stage and be mentally prepared. Once there is a large deviation, you must conduct consultations in time to find the reasons.

This is just to protect the fetus.

In order to accumulate more delivery experience for the Wenpo, all pregnant women in Beijing can receive free delivery, which makes the Wenpo who is determined to be very tired.

This was all thought of by professors, teachers and students at Xinglin University. Even Zhu Ciying himself did not expect that they would cause such a big disturbance. However, this is indeed in line with the essence of thought that Yu Chang showed in "Medical Law". He used norms as much as possible to record various physiological and pathological reactions as a reference for practicing medicine and treating diseases.

"Master, you have found a new seedling." Cheng Lin quickly walked through Yu Chang's office. Seeing that his master was writing at his desk, he couldn't wait, so he immediately reported it.

Yu Chang's hand trembled, he raised his head and said, "Take it serious?"

Cheng Lin nodded and said, "It's a student in my class who is debating with others about acne vaccination techniques. I heard it and I'm waiting outside the door now."

Yu Chang put down his pen and said, "Bring it in."

Cheng Lin turned around and soon brought in a young man around the age of twenty.

"Tell me about the vaccinia technique I mentioned before." Cheng Lin stood beside Yu Chang and said to the student.

The young man saluted Yu Chang first and said, "Student Wu Xinglin, who was a general practitioner of a mountain teacher before entering the school, is stationed in Huguang."

Yu Chang nodded. According to the new medical system, general practitioners are considered doctors who prescribe prescriptions, but because their profession is not perfect, they are not divided into subjects. After five years of studying at Xinglin University and passing the assessment, they are qualified as general practitioners. If you want to reach the attending doctor level, you have to study for another three years of professional subjects.

Only at this stage can one be qualified to become a disciple.

"The Miao people in Huguang have the custom of raising cattle. It can be said that there must be cattle in a well-off family." Wu Xinglin said: "When students were in Huguang, they found that there were very few smallpox damage among the Miao people, thinking that it was because of the water and soil. A few days ago, students heard that students had a discussion about human acne techniques and suddenly had a whim. If human acne can remove poison, then cattle are much larger than humans. Can they remove more toxins? Miao people are not harmed by smallpox, because they have already dyed cattle?"

"It's not easy to think of a cow." Yu Chang praised and said intimately: This idea is consistent with His Royal Highness the Crown Prince, which shows that this son is indeed outstanding.

Wu Xinglin thanked him and said, "So the students spent several days searching for the cowpox, and finally lived up to their expectations. Sure enough, they were able to find it."

Yu Chang and Cheng Lin looked at each other and said to each other: I spent a lot of effort to search but couldn't find it, but how did he search?

Wu Xinglin quickly explained the doubts of the two teachers: "It is not easy to find acne from cows, but it is much more convenient to find it from people. Students are looking for cattle raising homes in the capital. Any cow servants and cow owners have acne scars on their bodies will most likely have cows on their bodies."

The two suddenly realized.

Originally, the basis for using cowpox to treat acne was the same smallpox. Since it was the same, there was a possibility of mutual contagion. The cows had hair and were large in size, so it was not easy to find after the acne sores healed. However, it was very obvious to people. Most of the acne scars were concentrated on the face and limbs, not to mention that you could ask: Have you ever had acne before?

The cowpox was found, and the remaining problem was the dosage.

If the dose is too heavy, the child will still die if he cannot bear the acne poison. This is why human acne is not favored by the crown prince. If the dose is too light, whether acne can be successfully developed is different from person to person. When human acne is vaccinated, some children will be infected when playing with the child, while others will not respond when they wear the child's clothes.

"Let's try it out." Yu Chang said: "Start with the death row prisoner."

As long as people who have never had acne may be infected with smallpox, they are not limited to their age. Moreover, adults have strong resistance and hope to survive if the dose is heavy. As for death row prisoners to be used for experiments, it is considered natural for this era. Moreover, the Ming Dynasty is a benevolent country after all, and any death row prisoners who participate in vaccination can be exempted from death and sentenced to exile in Liaodong.

"Have you become a disciple?" Yu Chang asked Wu Xinglin.

Wu Xinglin said: "Students are still re-studying the general subjects and have not yet divided the subjects."

Yu Chang pointed to Cheng Lin, his land: "He is your master."

Wu Xinglin was immediately overjoyed and hurriedly said, "Disciple Wu Xinglin pays homage to his mentor." (To be continued...)
