The previous song was naturally copied, and the later "Song of Duck", although it is borrowed from "Song of the Goose", is also Jia Min's original. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Jiao Li has some literary foundation, and can also calculate some basic accounts. He was still quite confident in his studies, thinking that he would not have much effort.

However, next, what Jia Min taught, he felt blindfolded.

Why? If you don't follow the routine, it's just a ghost drawing.

The first thing to teach is arithmetic.

After Jia Min wrote one, two, three, four, five, six, seven, eight, nine, and ten on the board, he wrote 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 below.

What is this? I've never seen it before!

"This is called Arabic numerals, and in the future, when you learn to do arithmetic, you will use this number, and in the future, you will use it in the reckoning. Now, you write as it is, and you must write it well. Tonight's task is to write these ten numbers. I'll take the test in a while, and whoever can write will go back to sleep. ”

"Fourth master, this Arabian, whose uncle is it?"

Nan'er asked.

Jia Min was so angry that he couldn't wait to kick Nan'er a few times. After thinking about it, he was not to blame, so he forcibly suppressed the fire and did not have an attack.

"Well, this Arab is a barbarian, far away from us, you don't know him."

Alas, the difference in time!

A few people learned it seriously, and although they began to be clumsy, they gradually got on the road.

Jia Min walked down from time to time to take a look, pointing and pointing. Among several people, Ping'er wrote the best, and it seems that people are still relatively clever. Female workers do a good job, and it is also helpful to learn these things.

In the future, I should be able to write better than those beauties in my previous life. The beauties of the previous life, especially the entertainment stars, seem to have few people who can write well. That is, the signature is practiced to bluff people.

Nearly an hour later, Jia Min called a timeout. He was going to have a rehearsal with Jiaoli to prove the usefulness of Arabic numerals and pique the interest of the men.

So, he found an abacus, Jiao used the abacus and the Chinese characters one, two, and three, and Jia Min used mental arithmetic and Arabic numerals for one, two, and three ............. Write it out at the same time.

Naturally, Jia Min had to be a big step ahead of Jiao Li when he returned.

Jia Min took a test, and Jiao Li, Ping'er and Nan'er all wrote it out. Ning'er, Fenghua and Xueyue made a few mistakes, but it was okay, so I asked them to write after they went back, and I would test them again tomorrow.

The first time you take a class, the difficulty should not be too great, and the amount of learning should not be too much. Otherwise, it will undermine their confidence.

Next is the literacy class, which is also the ghost drawing of the Jiao Limeng circle: Hanyu Pinyin.

This time, Jia Min wrote only three vowel letters: a, o, and e. The requirement is to be able to write and read. Read it aloud and write it repeatedly. There is no other way than intensive training.

After another half an hour, Jia Min took the test again. This time it's good, it's all going to be, and it's over today.

When he walked out, Jiao Li asked Jia Min if he had to buy an abacus to learn arithmetic, and if he did, he could buy it back by the way when he entered the city tomorrow.

Jia Min said, let's not use that thing. What I want to teach is mental arithmetic, what do you want to do with an abacus? Blame the trouble.

What is mental arithmetic?

Jiaoli is in the circle again.

"How's your study?"

Ping'er asked Jiao Li.

"Alas, although I understand a little, I am still confused."

"Great." Ping'er became excited.

"Is this alright?"

"I'm confused too."

I see!

After everyone left, Jia Min found out the "Thousand Character Text" and "Hundred Family Names", spread out the paper and copied them down, the spacing was relatively large, and then began to label each character with Hanyu Pinyin.

In the future, he will use this as a blueprint to compile a set of literacy textbooks and a dictionary.

This is a relatively large project, and Jia Min has a lot to do, and he doesn't have so much time and energy.

Moreover, compiling a dictionary is a very professional matter, involving many issues such as political correctness and suitability to the characteristics of this era. Not something he could have done on his own. He needs a suitable helper to fulfill his intentions.

Alas, there is still a lack of talent.

The next day, the ordered raw materials such as coal and iron began to be purchased. The stove had been set up the day before, and Blacksmith Liu began to light the fire. Since it has not dried yet, it is just slowly baked over low heat.

Ping'er arranged a place for Blacksmith Liu and told him that he would eat and live here in the future, and Blacksmith Liu was very happy and agreed without hesitation.

Not only because you can run less and work more to earn more money in the future, but also because you can save money to eat at home by eating here.

For a blacksmith engaged in heavy manual labor, eating is actually a large expense.

Jia Min took Ning'er and Nan'er to the original half-built houses.

Ning Er and a pile of white ash, and then began to paint the wall.

Under Jia Min's command, Nan'er began to dig a trench on the ground in the house.

Two bricklayers hired by Joli also arrived and began to raise the walls of the watermelon orchard and orchard. When I saw the pressure well when I was fetching water, I was amazed, and it was really convenient, and I sighed that if I had money, I would also fight one. Save yourself from fetching water from the well. In winter, one step slipped, and if I didn't get it right, I dropped the bucket into the well.

The carriage of Wanjiayao came, and it was pulled with fragments of porcelain. These fragments are useless, they still occupy space in the kiln, and Jia Min saw them there yesterday, so he asked Boss Wan for some.

Boss Wan was very cheerful, and told him to pull as much as he wanted, as long as he gave money to the foot of the car.

These pieces are intended to be glued to the edge of the fence to prevent anyone from climbing the fence.

Ping'er saw that Jia Min was tossing in the house again, so she walked over and asked what she wanted to do. Jia Min said that he wanted to raise pigs, and Ping'er was very surprised.

Raising pigs is raising pigs, why do you still paint the wall? What are you digging a ditch for? Besides, where is there a pig in such a nice house?

While in doubt, the people recruited by the advertisement came to see the well, and Ping'er had to go back and greet Fenghua and Xueyue to receive the visitors.

While busy working, he complained that Jia Min was a loser again.

Pig raising in this era is actually relatively primitive. Most of them are free-range, that is, the pigs are driven outside to graze and then driven back. For this purpose, there is also a special profession - swineherd.

The pigs were full of food outside and rushed back and put in the pigsty.

This pigsty is also very primitive. The better ones are the stone and brick walls, and the worse ones are the ones that are made of wood and boards erected in a circle, called rods.

The more advanced ones are built with a straw hut, and many don't even have a shed. Wind and rain leakage on all sides is the norm. The pigs eat, drink, and sleep here, and it is often stinky.

The growth period of pigs is also long, and it takes two or three years for ordinary pigs to be slaughtered from birth to the end. Some even came out for four or five years.

When slaughtered, it is generally relatively large, at least 300 catties. Although it is relatively large, the growth period is too long. From the point of view of economic benefits, it is actually very uneconomical, but it is a process of making up money with change.

What Jia Min wants to do is a modern rapid pig breeding method, and it will be slaughtered in six months.

Putting the pigs out is exercise. Exercise burns calories. Calories come from fat, and fat is fat. As a result, pigs are reluctant to gain weight, and their growth rate is slow. This is the main reason for the long cycle of pig breeding in ancient times.

Jia Min was kept in captivity in the house, and the amount of movement of the pigs was very small. Moreover, the feed he fed to the pigs was the lees of sake brewing after making sake. This sake lees is different from the sake lees made by others, not rice husks and sorghum husks like others, but something similar to corn porridge, which can be eaten by everyone.

This sake lees is not only nutritious, but also has some alcohol left in it, so after the pig eats it, it is like a person who has drunk wine, and often falls asleep and is more willing to grow fat. Not only is it fast, but it is also easy to grow fat, which is the most suitable for this society.

In modern society, pigs are generally slaughtered when the pigs grow to about 200-220 catties. The reason why this is the case, instead of letting it grow to three or four hundred catties before it is slaughtered, is because at this time, the benefits are maximized.

Pigs grow fastest before 200 catties. After that, the speed slowed down. As the pigs get bigger, more and more feed is consumed, while meat production decreases. Economically, it's not cost-effective.

In the words of economics, the marginal effect is decreasing.

The pig grows to 200 catties, and the time is 6 months, which is the reason why it is generally slaughtered in 6 months. Most people call this the fast pig farming method, but it is actually unpleasant.

Laymen always think that pigs like dirty and messy environments, but this is a complete misunderstanding. Pigs also like a clean environment, but people don't give it this environment.

In many physiological indicators, pigs are very similar to humans. In fact, the environment suitable for human survival is the environment suitable for pigs. That's why Jia Min kept pigs in the house, painted the walls, and dug ditches. Digging a ditch is to discharge the pig manure in time through flushing, keep the environment clean and tidy, and help prevent and cure diseases.

Ping'er didn't understand these truths, so she naturally thought that Jia Min was a loser again. When the account is settled in the future, she will understand that in fact, this is not a loser, but a fortune.

Jia Min was working here, Ping'er came to look for him, and she was in trouble.

It turned out that more than 20 people who had come to consult about drilling wells had watched Ping'er's demonstration and listened to the introduction, and they were very interested and wanted to make an appointment to drill wells.

Just when she was about to register, Ping'er found that she couldn't write, Fenghua and Xueyue, so she had to find Jia Min.

Jia Min registered one by one, and more than a dozen people paid the fixed money, Ping'er collected it, Jia Min issued a receipt, and then left.

Subsequently, people came one after another, and Jia Min couldn't leave. When I'm free, tell Ping'er, this time you know the use of literacy, right? If I happen to be away from home today, these businesses might be gone.

Ping'er's face was a little red, but he also knew that what Jia Min said was right, and it was not easy to refute.

"The slave knows, and it won't be possible to study hard in the future."

is a little coquettish, Jia Min is no longer embarrassed to say it.
