Just when Tang Jian and his group went north to Shizhou, there were many people in Lishi County. They had already rushed all the way to the Qinling area. The ones running in the front were the Mawang family.

Although these two businesses have always been competitive in Lishi, they leave Lishi County, and they usually choose to cooperate and combine the power of the two businesses into one place. They are much stronger than a single business. They are not only more competitive, but also more secure in terms of security. In this era, many merchants in various places are also like this.

They came quickly, but the men sent by the emperor came faster. Several places where dura tree production have been guarded by the officers and soldiers, and no one else can interfere.

So they had to go to those more remote mountain villages, hoping to find some sources of goods. Earlier, after learning about the benefits of such rubber-soled leather boots, many local merchants in Lishi County believed that in the near future, the production of this Eucommia ulmoide rubber will become another important industry after silk and hemp grain. All of them want to win an opportunity for themselves before this industry emerges.

In the Qinling Mountains in October of the lunar calendar, the weather is cold and wet. The group crosses mountains and ridges, trek between small mountain villages, and buys seeds of duo tree from local farmers.

It is difficult to walk on the mountain road and the weather is bad, but none of the people in this group complained. In these days, for those who often travel to merchants, suffering is the most basic. It is not only a matter of transporting goods, but also a lot of trouble. It is not easy to find a place to stay in the wilderness.

"Your brother and the others have not returned yet?" On that day, Ma Feiyang came to Xipo Village again. Luo Yong saw that he was holding a teacup in his hand and looked at the heavy snow outside with a sad look on his face, so he asked.

"I'm afraid I'm entering the mountain." Ma Feiyang put the teacup in his hand on the kang table, and he leaned lazily to the side and sighed.

"There are so many of them, so I'm not afraid of anything." Luo Yong comforted: "I heard that there were many people going to the Wang family this time?"

"Well, your mortal enemy, Wang Jinhuai, has also gone." Ma Feiyang said with a smile.

Luo Yong smiled: "What kind of mortal enemy is just a few encounters."

At this time, he was squatting on the kang, grinding ink, dipping a small brush in ink, brushing a square wooden board, making the whole board dark.

Wang Huaijin, the guy who spoke wildly at the beginning, told Luo Yong that he would not cry without seeing the coffin. He was also a bad luck. At this moment, this joke has spread all over the country. He is just a young man from an ordinary merchant family. He was labeled as a villain.

Luo Yong also got the nickname of a coffin board because of this, and he didn't think there was anything wrong with it. This nickname is quite powerful and has some magical use to ward off evil spirits and offend villains.

"What are you going to do?" Ma Feiyang asked him.

"Blackboard." Luo Yong replied.

"..." Isn't the black board just a blackboard? Ma Feiyang felt that the answer was similar to the lack of answers. "What's the purpose?" he asked again.

"Writing." Luo Yong finished painting a board, stood it on the wall and hung it. Then he reached out and took another board to continue applying. He first applied ink on the wooden board, dried it and then brushed with tung oil. After it was dry, he could write on it with plaster.

It started to snow heavily here a while ago, Luo Yong asked Wulang to live in Zou Lizheng's house, and Wang Shaolinrong and the other two were with him.

In this way, Goro no longer comes back every day and never meets people all day long. Luo Yong is also a little worried. The Zoulizheng family is naturally good, but in terms of living conditions, it is definitely not as good as the Luo family.

Luo Yong has been thinking about these days. All the things he has on hand are on track and he can free up his free time. Why not take advantage of this winter to teach arithmetic in the Xu family's guesthouse.

He could teach Arabic numerals first, and then teach decimal fractions. These things were all the contents of primary school mathematics classes in the 21st century, which were relatively simple. Generally, as long as you learn these contents, daily life will be enough.

At that time, Luo Yong can also bring Goro back together. In this way, even if Goro doesn't go to school in Xiaohe Village, this winter will not be considered abandoned.

The old lady, second lady and fourth lady all have to learn. Other people's teachers don't accept female students when they start classes, and Luo Yong has no choice but to start classes by himself, so he doesn't want to point fingers. Not only his sisters, but other young ladies in the village want to learn, he also needs to teach them.

I felt calm in my heart. Two days later, before Wulang and his school finished school, Luo Yong and Wang Danglin Xingyi went to Xiaohe Village to pick up the children.

The meaning of these two families is that they actually want their children to make friends with Luo Wulang, so this time Luo Yong said he wanted to take Wulang back and teach him some arithmetic at home. They asked if they could let their children learn together. After receiving a positive answer, they went to Xiaohe Village to pick up people together.

The husband from Xiaohe Village didn't say much, but asked these three children to review every day after they returned home, so as not to waste their studies.

Then Luo Yong and others went to Zou Lizheng's house again, thanking him for taking care of these boys over the years, and brought some mutton and rice noodles over there. Of course, the gentleman gave it to him before.

As a teacher, you don’t have to worry about food. Luo Yong thought about it. After he started teaching, the family should not worry about having no meat.

With this beautiful vision, the arithmetic class in the Xu family's house soon began to teach. The earliest group of students were his disciples. Based on the principle of unconditional trust in their masters, even if the numbers taught by their masters seemed strange and difficult to remember, they all bite the bullet and learn them.

They don’t come every day, they will come every day when they are free. Sometimes they are in class, some leave temporarily, and some come halfway, and Luo Yong doesn’t care much about it.

Class is every afternoon, after lunch, before dinner, some people from the city came over to watch the excitement, and they could have dinner at the Xu family's guest house, stay for one night, and then return to the city the next day.

Teaching is actually not that interesting. Luo Yong was quite enthusiastic at the beginning. Later, every day he watched the big men counting one, two, three, and four with their fingers. He was a little tired of watching and yawning a few times during class.

The disciples all said that their master is going to grow up again. Children like to sleep when they want to grow up. Their master is only sixteen this year, so they must still grow up.

After recognizing the numbers, it is simple addition and subtraction. This is not difficult to teach, because most of his students are adults and they inevitably have to use some arithmetic in their lives, so most people know how to add and subtract simple.

After that, something interesting came. Luo Yong taught these people vertical calculations. Then the natives of the Tang Dynasty suddenly discovered that as long as a piece of gypsum and a blackboard, whether it was five-digit, six-digit or seven-digit, they could all get it. This was really a sense of accomplishment!

After this incident reached Lishi County, the number of people visiting and listening increased sharply, and the business of the Xu family's hotel immediately improved.

When Tang Jian and his group arrived in Lishi County, a blackboard was already roaring in the area. Many people were hanging a small blackboard the size of a palm on their waists, holding one or two pieces of plaster in their purse, making a clanging sound when they walked.

The team was ordered to rest outside the city for a while, and the people in charge of food were asked to go to the city to buy food. Tang Jian himself took two followers to go to the city for dinner.

Just as I sat down here in a familiar restaurant, I heard a runner settle the accounts for the table next to me: "Twelve cents for pottery jars, ten cents for hot pots, fifteen cents for sake, and a few other side dishes cost a total of six cents, a total of forty-three cents. You see, my account is correct?"

A table of food costs more than 40 cents, which is quite good in Lishi County. Tang Jian listened on the side and knew that the runner was correct. He just couldn't understand what was written on the small blackboard handed over to the guests at that table. Why didn't he understand at all?

"Not bad, it's exactly forty-three folks." The guest at that table looked at the small blackboard, nodded, and then paid for it with great pleasure.

There were more than forty copper plates strung together and there was a small hanging in their hands. They were heavy in their hands. After the waiter collected the money, he happily went to the counter.

He has always been agile and very serious in his work. He used to be highly valued by the shopkeepers. A few days ago, he was arranged to go to Xipo Village to study arithmetic for more than ten days.

He was very determined and could settle the accounts when he came back. He held a small blackboard every day to settle accounts with the customers in the store and was responsible for collecting the money. Although the customers may not be able to understand them, he seemed very satisfied with this transparent way of checking out. The store said that from this month, he would have to raise his wages.

While waiting for the meal to be served, Tang Jian and others had the honor to visit the checkout process several times. Looking at the strange numbers on the small blackboard, and then looking at the locals who seemed to understand it very much...

"This is Lishi County, right?" Mr. Tang felt a little strange in his heart. Could it be that he had come to some strange place.

There are also strange stories in the market, saying that some people took the wrong path as they walked, and by chance they went to places like fairyland or underworld. Could it be that their group of people were also going a different path somewhere?

At this time, Tang Jian didn't know that there was still a saying in this world.

"Mr. I'm joking. Where can I be if this is not Lishi County?" Seeing that the guests at his table seemed to be either rich or noble, but the food was served a little slowly at this time, the shopkeeper came here to chat with him.

"Why do I think the words they write are so weird?" Tang Jian asked.

"That was taught by Luo Sanlang. Luo Sanlang went to Beijing to meet the saint. In the Chang'an city, he learned this very simple and easy-to-use arithmetic method from a Hu Shang. Now it's winter leisure time, so he taught this method to everyone."

When he said these words, the shopkeeper's face was full of admiration. Hu Shang was also cunning. How could they learn their methods easily? I don't know how much benefits Luo Sanlang promised the other party and how much effort it took to accomplish this. However, he had no intention of hiding his own private life at all. How many people can there be such a kind and righteous person in the world?

"So that's the case." After hearing what the other party said, Tang Jian also breathed a sigh of relief. As long as he didn't go the wrong way, it would be fine.

It is not too incredible to say that Luo Sanlang learned this kind of arithmetic method from Hu Shang. After all, there are more than two strange things created by those Hu Shang.

The atmosphere of the Tang Dynasty society was also open. Hu horses, Hu clothing, and even Hu women were acceptable and welcomed. Now, adding Hu arithmetic method is not a big deal.

The Hu people mentioned at that time did not refer to the nomadic peoples in the northwest. Europeans, Africans, Arabs were usually called Hu people. Among the Hu people, there were Hu Shang and Hu Nu. In Chang'an City, there were even many Hu girls who were good at singing and dancing.

What surprised Tang Jian was that Luo Yong could actually get this secret method from those cunning Hu Shangs, and then open the door to teach without any secrets.
