At this time, the ministers began to go to the book, thinking that the emperor's younger brother Zhu Youzhen was too old, and asked the emperor to crown him king. The birth of the crown prince, this is the proper meaning of the question, so the emperor named Zhu Youzhen as the king of Xin, as for his fief, after the ministers discussed, I hope that the emperor will seal the king of Xin in Nanning, Guangxi.

Zhu Youxiao felt that Guangxi was too far away, and suggested finding a closer place to settle King Xin, but he was unanimously opposed by the ministers. Ye Xianggao said a little bluntly: "Those who are far away can comfort the heart of the emperor's relatives." And the ministers, who have always been careful about their words, feel that this sentence is well said, it is said beautifully, and it is said to be a beep.

Zhu Youxiao had no choice but to agree to divide King Xin into Nanning Mansion. However, on the grounds of the unappeasement of Nanning, King Xin was temporarily left in the capital, although the ministers objected, but at his insistence, they had to reluctantly agree.

At the beginning of July, the first examination was held in the hall of Beijing Normal University, which Zhu Youxiao called the mid-term examination, and the official name was the semi-annual examination. The results of this examination made Zhu Youxiao, who had experienced the education of later generations, stunned: the Teachers College and the Clerk's College were all qualified, and the excellent rate reached ninety percent.

In fact, this is his habitual thinking, and it is normal for students in later generations to be bored with learning because it was already national education at that time, and there will always be some people who are not interested in learning. In this era, there are few opportunities for education, and learning for free in an environment like the Beijing Normal University is something that has never been done since ancient times.

The students of the graduate school are divided into six subjects, of which the students of the two departments of agriculture and equipment have never attended classes in the classroom at all, and directly practiced.

The Agricultural Division is divided into two small classes, one class is in the Shanglin Yuan Supervisor to practice with the Liang Shepherd, Fan Yu, Lin Heng, and Jia Vegetable Bureau, and the other small class is to study with those old farmers in the Si Yuan Bureau.

The equipment class directly enters the Armory Bureau, and according to their own interests, they choose three categories: armor, firecrackers, and artillery, and learn from the three squires of the Armory Bureau.

Students in the four subjects of astronomy, geography, arithmetic, and medicine studied in the university hall, Xu Guangqi and Western missionaries could teach astronomy, geography, and arithmetic, and medicine was taught by the Tai Doctor of the Tai Hospital.

And the emperor Mr. Zhu Youxiao is the only professor of six subjects.

On the morning of May 11, after he had breakfast, Ke said: "Today is agriculture, your majesty, why do you want to teach students agriculture, you have never done it yourself, there are so many old peasants, who have served the crops all their lives, won't they?" ”

Zhu Youxiao said with a smile: "Nurse, you don't know, they know how to grow crops, but they don't know why they do it, as for some things I know, they haven't heard of it, although I haven't done farm work, but I know how to increase production better than the old farmers, this is called the power of knowledge." ”

He came to the Siyuan Bureau proudly, and Song Yingxing, the squad leader of the agricultural class, stepped forward and said to him: "Your Majesty, today I am going to talk about breeding." (Zhu Youxiao stipulated that during his tenure as a professor, students only had to bow to him, not kneel.) ）

Song Yingxing is a lifter, in his thirties, and after failing to take the test many times, he has given up the idea of the imperial examination. It happened that this time the Beijing Normal University Hall was enrolled, and he came to take the agricultural exam, and the result was very good, and he was appointed as the class leader of the agricultural class.

Zhu Youxiao smiled: "Okay, let them come to the lobby." ”

There was a blackboard in the lobby of the Siyuan Bureau, Zhu Youxiao entered the lobby, and the students stood up and saluted together: "Hello teacher!" ”

Zhu Youxiao waved his hand and said, "Hello students, today we will start talking about genetic issues. What is heredity? We plant a pumpkin seed into the soil, and after a period of time, a pumpkin will grow, but not a winter melon. ”

"Then we can summarize the concept of heredity: the phenomenon that the next generation of a species is the same as the previous generation, that is, heredity, we call the previous generation the parent, and the next generation the offspring......"

Of course, the biological knowledge he learned back then was far better than the current level, but the point was that he couldn't verify it, and he couldn't say that there was DNA in the organism. So let's start with the visible phenomenon, and after the microscope in the glass workshop is manufactured, let's slowly talk about cells or something, as for DNA, it is estimated that he will not be able to talk about it in his lifetime, because it is not something that ordinary light microscopes can see.

After a total of an hour, after explaining the laws of heredity in a different way, let them experiment with some plants, and then the class ended. After class, he said to Song Yingxing: "You have to record what I said in detail, and when I finish a part, I will hand in the record, and I will revise it to be a textbook for agriculture." ”

When he returned to the palace, he communicated with the cabinet and gave instructions on important domestic and foreign issues.

In the afternoon, it was his parent-child time, he played with the little princess Zhu Shu'e for a while, and then went to see Zhu Ciran, who was either breastfeeding or sleeping, and exchanged parenting experiences with the three wives.

May 12, Bureau of Ordnance. "Students, you see, on this smooth glass, the speed of the car rolling down will gradually increase, why is this happening, because they are affected by the force, this force we call gravity ......"

May 13, Astronomy Class of Beijing Normal University.

"Let's take a look, this sun moves like this, then this moon moves like this, when the earth we live in blocks the sun's rays, this part of the moon is invisible, and that's why the phases of the moon change......"

May 14, Geography Class of Beijing Normal University.

"This river is what we call the Yangtze River, many times it is directly called the Great River, so where is its source, come, we look at the map, it is here, of course, we can't see it now, but after we tame the Mongols, we can send people to check this Yangtze River, the common source of the Yellow River, maybe then we can see the source of other big rivers is also here......"

On May 15th, the arithmetic class of Beijing Normal University Hall.

"Let's see, this is a triangle, so how should its area be calculated, make a line from this angle, perpendicular to the side below, we call this line perpendicular......"

May 16, Beijing Normal University Hall Medical Class.

"Ladies and gentlemen, why do I stipulate that you must drink boiled water and not raw water in the army? Why is the cloth used to wrap the wound after an injury boiled in boiling water and then exposed to the hot sun? Why do you use alcohol to scrub your wound after an injury? Because right here in the air, in the water, there are tiny, tiny bugs, and soon we're going to be able to build equipment for people to see them. I call them bacteria, and many times people get sick because of bacteria......"

On May 17, after breakfast, Ke said: "Today is a rest day, Your Majesty does not need to be a professor." Really, there are so many things to do every day, and there is still the spirit to be a professor, wouldn't it be better to choose a few more concubines? ”
