In the past few days, Zhao Zhen and the others have occasionally gone to the back garden, because they have been staying in the back for a long time, and there is a lot of backlog in government affairs.

In the year of Jing You, the Great Song Dynasty was quite smooth, and there was not much turmoil, but in the first two years, there were floods in Jianghuai, and the aftermath was not small, and last year Jianghuai did not pay taxes, and Zhao Zhen used internal funds to help the Jianghuai region pay, and now the local people are still living very difficult.

In addition, there were some civil unrest in various places, such as the rebellion of peasants on Liangzhejiang Road at the beginning of this year because of the high salt and tea taxes.

In the Song Dynasty, salt and tea were not made by the government, but were apportioned to the people, and were maintained by the salt and tea people drying sea salt and planting tea, and the government would control the salt and tea fields.

These peasants are the so-called "Guanjian salt households" and "Guanjian tea households".

After the salt and tea are ready, the government will carry out a unified purchase, that is, more than ninety percent of the salt and tea will be collected at a very low price, almost like a robbery.

For example, the price of sea salt collected by salt farmers is about two or three yuan a catty, and the government dares to sell it for twenty or thirty yuan when it sells it.

This is still relatively cheap, when it is expensive, it can reach 50-70 Wen, and even 100-300 Wen, which is dozens or hundreds of times more expensive.

Tea is the same, a little bit of tea is a few dollars to collect, a better tea is more than a dozen Wen, at most no more than 30 Wen, when it is sold, it is 100 to 300 Wen a catty, and the head gold and wax tea can reach 4 or 500 per catty.

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

When the magistrate saw it, how could this be done? Isn't this robbing us of our money? So we cracked down on this kind of behavior.

They dealt heavy blows to salt and tea households, as well as private traders who had no tea merchants and unofficial salt merchants, and arrested people everywhere, with the result that salt and tea households often rebelled in the southeastern region.

Zhao Zhen has been very busy these days, and he has dealt with all these government affairs, it is still the old rule, if a small-scale uprising can be co-opted, it will be co-ordinated, and if it can't be co-opted, the local army will be sent to suppress it, which can be regarded as a reluctance to solve these troubles.

At this time, it was about 10 o'clock in the morning, the ancients got up early and went to bed early, the emperor and officials got up at 3 o'clock in the morning to go to work, and now it is actually the afternoon time, and it is time to go to bed in the evening in another seven or eight hours.

At this time, Zhao Jun was in class.

His current routine is to get up at 4 o'clock in the morning to wash up and have breakfast, then ask the imperial doctor to get a needle, and then prepare for today's lessons, and finally give a few classes to the students at 5 o'clock, the main content is mathematics and Chinese classes.

In math class, he has now taught multiplication tables, and students should learn division after they have memorized about it, and in Chinese class, he teaches pinyin.

I don't know why, the foundation of these kids is really poor.

It stands to reason that pinyin class is the content of the first and second grades, but the children are almost zero-based, so Zhao Jun has to wonder what the last group of volunteer teachers are doing.

After taking Chinese and math classes, it is generally 10 o'clock in the morning, after lunch, Fan Zhongyan will help him to bask in the sun in the yard, or go to the village to talk to Lu Yijian's old men and old ladies to talk nonsense, and eat dinner at 3-4 o'clock in the afternoon, and basically go to bed at about 6-7 o'clock when it gets dark.

That's what he does in the day.

After being able to come out for activities, Zhao Jun prefers to join in the fun among the old people, he plans to mix up popularity, establish reputation and prestige in the village, so that he can mix in the village in the future.

But in the past few days, Lu Yijian and they have their own government affairs, and Fan Zhongyan excused themselves by saying that they went to work in the fields, so there is no one to chew his tongue with him now.

After all, Fan Zhongyan was mostly silent, and except for occasionally asking about Qingli's new policy, he didn't ask about anything else.

Therefore, when there is no one to talk to him, he can only torture the students, drag out a class, and talk about something else.

After listening to Chinese and mathematics all morning, everyone will definitely not be able to learn it, so Zhao Jun will talk about basic physics.

"Do you know why people can see?"

"Eye~Eye~!"

The following answers are all in one place.

Zhao Jun was accustomed to this crisp child's voice, so he said, "It's not the eyes." ”

"Is that~what~?"

"It's light!"

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

"Teacher."

Yaya stood up and asked, "Why is the light for us to see?" ”

"Because we have photoreceptor cells in the neuroretina of our eyes, we can distinguish the color and intensity of light through the sensing of these cells."

Zhao Jun pointed to his blindfolded eyes and explained: "Light is a type of energy that travels in the form of electromagnetic waves, and luminaries convert other energy into light energy and emit light waves. When light waves shine into the light-sensitive cell body in the eye, the eye can see the luminous body. So if we're in a completely dark environment, without any source of light, the eyes won't be able to see anything. ”

"Listen~No~Understand!"

The students replied in unison.

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

Zhao Jun smiled, he didn't expect the students to understand, because this is the optical content of the first year of physics, and now he is just saying it as a trivial knowledge in an interesting physics class.

In the future, when they go out of this mountain village primary school and are admitted to the junior high school in the 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-kilogram iron ball and a 1-kilogram iron ball fall from mid-air at the same time, and the landing time is the same.

The children still don't understand this, Zhao Jun has a book of "Interesting Little Experiments in Physics", and he plans to teach the children a little physics knowledge when their eyes are better in the future, so that they can follow up on physics after they go to junior high school.

And just as Zhao Jun continued to take classes and teach some physics knowledge, Yan Shu on the side frowned, and after a while, he relaxed and whispered to Zhao Zhen: "Official, it seems that it won't be long before 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, and 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 now it is estimated that it will be soon, and didn't you hear him talking about "light"?" He himself longed to see, fearing that even if he could only see vaguely, he would have to take off his veil. ”

Zhao Zhen whispered: "Can you let the imperial doctor find an excuse to delay a bit?" ”

"It should work."

Yan Shu said: "Last time, he could only see two black shadows, and I believe he couldn't see them so soon. Tomorrow morning, when it is dark, ask the imperial doctor to show him again, and tell him not to take off the veil until his eyes are good, when it comes to whether his eyes can be restored, I think he will be obedient in the future. ”

"Hmm."

Zhao Zhen nodded.

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

Soon after the end of the class, he heard a crisp voice with surprise: "Da is here." ”

In ancient times, there was a very interesting point that the father was called Ye, and the grandfather was called Dad.

Because the grandfather came from ancient times, he called his father Yeye, and gradually became a grandfather, such as "Grandpa has no eldest son, Mulan has no eldest brother" in "Mulan Ci".

By the time of the Song Dynasty, the father became "Dad" and "Daddy", and the grandfather became "Father-in-law", "Grandpa", "Weng Weng", "Big Daddy", etc., and even called the stepmother "sister".

These are recorded in "Records of Experiences in the Four Dynasties", "Quotations of Zhuzi" and "Farewell Chronicles of Longchuan".

Yan Shu is a native of Linchuan County, Fuzhou, that is, Fuzhou, Jiangxi Province in later generations, and they call their grandfather "Big Daddy" in the local dialect, which is still called so in many places in Jiangxi.

If Zhao Jun is from Jiangxi, he will be directly put into a goof.

But it's a pity that he is from Hunan, and they call their grandfather "grandpa" there, so when they heard Yaya's sudden name, they thought it was their Yi dialect.

But this is the case, which also scared Yan Shu enough, and hurriedly went up to hug Yaya, and then said to Zhao Jun: "Teacher Zhao, what about lecturing, Xiaoya has really troubled you these days." ”

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

But he obviously thought too much, because Zhao Jun didn't know the Jiangxi and Yi dialects, so when he heard Yan Shu's voice, he was immediately very surprised: "Village chief, you're back, where have you been in the past few days!" ”

Yan Shu saw that Zhao Jun was not unusual, and he breathed a sigh of relief, so he hurriedly said: "Isn't my wife sick, I took care of her for two days, and by the way, I went to the next village to call a few young men, I want to see if I can dig up another path down the mountain, you also know that our village is full of old and weak...... The next village is more than ten miles away from us, and we came back two days late. ”

Before he came, he had already thought of the wording.

Zhao Jun hurriedly asked, "Has the path down the mountain been dug up?" ”

"No, it's so fast."

"Okay."

Zhao Jun didn't have much hope, but he was not disappointed.

Soon the children were taken out by the old mothers guarding outside, Yan Shu handed Yaya to the old mothers 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 hippie smile: "The village chief has been away for a few days, and I haven't heard many jokes, do you want to hear the new Da Song jokes?" ”

Yan Shu's heart, which had been put down, suddenly picked up again, and turned his head to look at Zhao Zhen.

Zhao Zhen nodded expressionlessly.

Yan Shu had no choice but to bite the bullet and say, "Okay, but say it in advance, about Tai..... Zhao ..... Don't tell jokes about righteousness. ”

"That's a must, I know you're a fan of Zhao Guangyi."

Zhao Jun patted his chest, and then said: "Song Zhenzong sealed Zen in Mount Tai, and the Hanlin Painting Institute ordered a famous painter to create a large-scale painting called "The Official Family Sealed Zen in Mount Tai" as a gift, and the painter reluctantly accepted the job under duress.

When the painting was completed, a high-ranking official of the Song Dynasty came to inspect it, and he was surprised by the results: a group of Song Dynasty envoys with a carriage on the road was depicted, 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 Great Song Dynasty to send New Year's coins to Liao." The painter replied.

"What about the city?!"

"Shangjing, the capital of Liao."

"But where is Your Majesty?"

"Your Majesty has won the battle of Danzhou, and is sealing Zen in Mount Tai." The painter replied. ”

"Well, it's a funny joke."

Zhao Junle asked.

Yan Shu turned his head to look at Zhao Zhen.

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

In both ears and nostrils, it is as if hot air can come out!
