In the Song Dynasty, there was no law or order.

In the past few days, Zhao Zhen and the others only went to the back garden occasionally. Because they stayed behind for a long time, there was a lot of backlog of government affairs.

In the reign of Jingyou, the Song Dynasty was relatively smooth, without major disturbances. However, there were floods in the Jianghuai River in the first two years, which caused serious troubles. Last year, Jianghuai did not pay taxes. Zhao Zhen used internal funds to help the Jianghuai area pay. People's lives are still very difficult.

In addition, there are some civil strife in various places. For example, at the beginning of this year, farmers in Liangzhe Road rebelled because of the high salt and tea taxes.

In the Song Dynasty, salt and tea were not produced by the government, but were distributed to the people. The salt and tea farmers were responsible for drying sea salt and growing tea. The government would control the salt fields and tea farms.

These farmers are the so-called "official-supervised salt households" and "official-supervised tea households".

After the salt and tea are prepared, the government will conduct a unified purchase, which is to take away more than 99% of the salt and tea at a very low price, almost like robbery.

For example, the price of sea salt at salt households is about two or three cents per catty, but when the government sells it, it can be sold for twenty or thirty cents.

When it is relatively cheap, it can reach 50-70 yuan when it is expensive, and sometimes it can even cost 100-300 yuan. The cost of changing hands in the middle is actually dozens or hundreds of times more.

The same goes for tea. A lower-priced tea costs a few cents, and a better tea costs more than a dozen cents, and no more than thirty cents at most. It is sold for one hundred to three hundred cents per catty, and the top gold and wax-faced tea can even cost as much as Four to five hundred per catty.

Therefore, most salt and tea farmers would rather sell good salt and tea to private traders, and people are more willing to buy salt and tea from private traders. Because the quality of private tea and private salt is better and cheaper than official salt and official tea, there are no middlemen to make the difference.

The local government looked at it and wondered, how could this be done? Isn’t this stealing our money? So we severely crack down on this behavior.

They struck hard at salt and tea households, as well as private traders who had no tea merchants and unofficial salt merchants, and arrested people everywhere. As a result, salt and tea households often rebelled in the southeast.

Zhao Zhen has been very busy these days, dealing with all these government affairs. He still follows the old rules. If a small-scale uprising can be organized, he will collect it. If it cannot be collected, he will send local troops to suppress it. These troubles can be regarded as barely solved.

It was already around 10 o'clock in the morning. The ancients got up early and went to bed early. Emperors and officials got up at around 3 o'clock in the morning to go to work. It is actually afternoon time now. In another seven or eight hours, it will be It's time to go to bed in the evening.

Zhao Jun is in class at this time.

His current daily routine is to get up at 4 o'clock in the morning, wash up, have breakfast, then ask the imperial doctor to give an injection, and then prepare for today's classes. Finally, at 5 o'clock, he will give a few classes to the students. The main content is mathematics and Chinese class.

In math class, he has now taught the multiplication table. After the students have memorized it, they should learn division, while in Chinese class, he teaches pinyin.

I don’t know why, but the foundation of these children is really poor.

Logically speaking, pinyin class is a part of the first and second graders, but the children have almost no basic knowledge, which makes Zhao Jun have to wonder what the previous group of supporting teachers are doing.

After finishing Chinese and math classes, it was usually 10 o'clock in the morning. After lunch, Fan Zhongyan would help him go to the yard to bask in the sun, or go to the village head to chat with Lu Yijian's gang of old men and ladies. By 3 pm - I had dinner at 4 o'clock, and it was basically time to go to bed when it got dark around 6-7 o'clock.

This is his day's itinerary.

After being able to go out for activities, Zhao Jun prefers to join in the fun among the elderly. He plans to gain popularity and build up his reputation and prestige in the village so that he can get along well in the village in the future.

However, Lu Yijian and others had their own political affairs these days, so Fan Zhongyan used the excuse that they had gone to work in the fields, so there was no one to chat with him now.

After all, Fan Zhongyan is a taciturn person. Except for occasionally asking about Qingli's New Deal, he doesn't ask about anything else.

Therefore, when there was no one to chat with him, he could only torture the students, delay a class, and talk about something else.

After listening to Chinese and mathematics all morning, everyone was definitely not able to learn, so Zhao Jun talked about some basic physics.

"Do you know why people can see things?"

"Eye~eye~!"

All answers below.

Zhao Jun was used to the crisp children's voice, so he said: "It's not the eyes."

"What is that?"

"It's light!"

Zhao Jun raised his voice and said: "It is light that allows us to see, so everyone must believe in the power of light!"

"teacher."

Yaya stood up and asked: "Why is it the light that allows us to see?"

"Because there are photoreceptor cells on the neural retina in our eyes, it is through the induction of these cells that we can distinguish the color and intensity of light."

Zhao Jun pointed to his blindfolded eyes and explained: "Light is a kind of energy that spreads in the form of electromagnetic waves. The luminous body converts other energy into light energy and emits light waves. When the light waves shine into the photoreceptor cells in the eye The eyes can see this luminous body when it is in the body, so if we are in a completely dark environment without any source of light, the eyes will not be able to see anything."

"I don't understand!"

The students answered in unison.

"It doesn't matter if you don't understand. You just need to know that there is light to see."

Zhao Jun smiled. He didn't expect the students to understand it, because it was the optical content of first-grade physics, and now he just said it as a fun physics lesson.

When they go out of this mountain village primary school in the future and enter a junior high school in a town or county, they will understand the role of light.

In addition to light, he also said that the speed of free fall is not determined by weight, but by air resistance. For example, a 20-pound iron ball and a 1-pound iron ball fall from mid-air at the same time. The landing time it's the same.

The children still don't understand this point. Zhao Jun has a book called "Interesting Little Experiments in Physics". He plans to teach the children some common sense of physics when their eyes heal, so that they can follow up on physics after they enter junior high school.

While Zhao Jun continued to teach some physics knowledge, Yan Shu on the other side frowned. After a moment, he relaxed and whispered to Zhao Zhen: "Guan family, it seems that it won't be long. Zhao Jun will regain his sight, and we must prepare early.”

"So fast?"

Zhao Zhen was surprised. Zhao Jun had only been here for less than two months. If he was about to regain his sight, it would not be good news for him.

Yan Shu shook his head and said: "He was able to see things some time ago, and he is probably going to be able to see things soon now. And didn't you hear what he was talking about about "light"? He himself is eager to see it, and I'm afraid he can only see it vaguely. , he also has to take off his gauze.”

Zhao Zhen whispered: "Can the imperial doctor find an excuse to delay it?"

"it should be OK."

Yan Shu said: "Last time he could only see two black shadows. I believe he can't see them that quickly. When it gets dark tomorrow morning, let the imperial doctor look at him again and tell him not to take any pictures until his eyes are healed. Putting down the eye gauze affects whether the eyes can regain sight. I think he will be obedient. "

"Um."

Zhao Zhen nodded.

Both of them lowered their voices and whispered, while Zhao Jun was lecturing loudly.

Soon after the class was over, he heard a crisp voice with surprise: "Da 嗲嗲, you are here."

There is a very interesting point in ancient times that the father is called Ye and the grandfather is called Dad.

Because Ye originated from the ancient times when his father was called Ye Ye, he gradually became Grandpa. For example, in "The Song of Mulan", "My father has no eldest son, and Mulan has no eldest brother."

By the time of the Song Dynasty, fathers had become "dad" and "daddy", and grandfathers had become "father-in-law", "grandpa", "wengweng", "big daddy", etc., and even the stepmother was called "sister".

These are recorded in "Records of the Four Dynasties", "Zhu Xi's Quotations" and "Longchuan Farewell Records".

Yan Shu was from Linchuan County, Fuzhou, which later became Fuzhou, Jiangxi Province. Their local dialect called his grandfather "Big Daddy". This is still the case in many places in Jiangxi.

If Zhao Jun was from Jiangxi, he would be a gangster.

But unfortunately, he is from Hunan, where people call their grandfather "Grandpa", so when they heard Yaya's sudden call, they thought it was the dialect of their Yi ethnic group.

But Yan Shu was so frightened that he quickly went up to hug Yaya, and then said to Zhao Jun: "Teacher Zhao, I'm giving lectures. Xiaoya has really troubled you these days."

He wanted to chat with Zhao Jun immediately to distract him and prevent Zhao Jun from coming back to his senses and hearing that something was wrong through this "big babbling" sentence.

But he obviously overthought it, because Zhao Jun didn't know Jiangxi and Yi dialects, so when he heard Yan Shu's voice, he was very surprised and said: "Village chief, you are back, where have you been these past few days!"

Yan Shu felt relieved when he saw that Zhao Jun was fine, and said quickly: "My wife is ill. I took care of her for two days. By the way, I went to the next village to call a few young men to see if I could help the other ones." A trail has been dug down the mountain. You also know that our village is full of old and weak people. The next village is more than ten miles away from us, so we came back two days late. "

He had already thought of his words before coming.

Zhao Jun asked hurriedly: "Has the trail down the mountain been dug?"

"No, it's not that fast."

"All right."

Zhao Jun didn't have high hopes, but he wasn't disappointed either.

Soon the children were taken out by the old ladies who were guarding outside. Yan Shu handed Ya Ya to the old ladies in his house, and then said: "You don't have to worry, it won't be long."

"I hope so."

Zhao Jun sat back on his bed, and then said with a playful smile: "The village chief has been away for a few days, and I haven't heard many jokes. Do you want to hear new Song Dynasty jokes?"

Yan Shu's originally relieved heart suddenly became tense again, and he turned his head and looked at Zhao Zhen.

Zhao Zhen nodded expressionlessly.

Yan Shu had no choice but to bite the bullet and said, "Okay, but we must agree in advance that we won't tell any jokes about Tai Zhao Guangyi."

"That's necessary. I know you are a fan of Zhao Guangyi."

Zhao Jun patted his chest and then said: "Zhenzong of the Song Dynasty consecrated Zen in Mount Tai. The Hanlin Painting Academy ordered a famous painter to create a large painting called "The Official Consecrated Zen in Mount Tai" as a gift. The painter reluctantly followed the coercion. Accepted the job.

After the painting was completed, a high-ranking official from the Song Dynasty came to check and accept it. The result surprised him: the picture showed a group of Song Dynasty envoys advancing on the road with carriages, and there was a city on the horizon in the distance.

"What is this? Who are these people?!" the senior official asked angrily.

"The envoy of the Song Dynasty sent New Year's coins to the Liao Kingdom." The painter replied.

“Where’s that city?!”

"The capital of Liao Kingdom goes to Beijing."

"But where is your Majesty?"

"Your Majesty won the battle of Tanzhou and is enshrining himself in Mount Tai." the painter replied. "

"Well, this joke is very interesting."

Zhao Jun asked cheerfully.

Yan Shu turned his head to look at Zhao Zhen.

Zhao Zhen's tense face was as hot and red as a kettle.

It seemed as if steam could come out of his ears and nostrils!
