In the next few days, Zhang San went to the school when he had nothing to do, and supervised the studies of the "college students". At the same time, he also taught the arithmetic book he wrote to the two teachers.
When these two people got this book, they fell in love with the content at first sight, especially the symbols. Although abstract, fortunately there were notes next to them. They probably knew that these strange symbols were "one, two, three..."
This was what Zhang San did intentionally because there were no Arabic numerals at that time. In order to facilitate learning, he made detailed notes and explanations at the beginning of the book.
With Zhang San’s guidance and the fact that the two of them had mathematical skills, they learned very smoothly. They also admired Zhang San’s talent even more. Although Zhang San kept saying that these were taught by experts, the two of them didn’t believe it at all.
I think this is just Zhang Sanzang being clumsy and keeping a low profile.
…
"Sir, a woman came to the house and said she is looking for you, Sir. Her name is Xie Hua'er." Sister-in-law Li came to the school and found Zhang San and said.
"What? Xie Hua'er? What is she doing here?" Zhang San was very surprised, and suddenly felt guilty about being a thief.
"I don't know about this, but she keeps yelling that she won't leave until she sees you." Sister-in-law Li was also very surprised. Where is this romantic debt left by the Lord?
"Master Zhou, Master Hu will be here in the next few days. There is something going on at home. I'll go check it out." Zhang San put down the arithmetic book in his hand and apologized to the two of them. Originally, he said that he would explain some equations to them in detail today.
But now it seems I can only teach another day.
"My lord, you are busy first, we will explore it ourselves." Master Zhou replied.
After bidding farewell to the two wives, Zhang San got on his "BMW" and sauntered back home. Along the way, he was wondering why Xie Hua'er suddenly ran to his home.
When I returned to my house, I saw Xie Hua'er sitting in the living room.
"Why are you here?" Zhang San asked directly.
"What's wrong? I haven't seen you for so long. Don't you miss me at all? That day you left without saying goodbye, I was very sad for a long time." If Xie Hua'er had lived in her previous life, she must have been an acting genius. With just two sentences, she would have
She burst into tears, making Zhang San look like a heartless man.
"Stop it. First of all, I told you that I already have a lover. If you say this, people will misunderstand you. Secondly, I don't think about you at all and we have no relationship. So what do you want to do here today?
"
Zhang San was a little angry. Why did he find it at home? Didn’t he accidentally touch it that day? Haven’t they already been explained?
"Humph! Why don't you come over to see if you can do it? Do you have to be so heartless?" Xie Hua'er pouted her lips and pretended to be angry.
However, Zhang San didn't agree with her at all, and thought to himself: Is this girl trying to come over and blackmail her for a few bucks?
If Xie Hua'er knew that Zhang San thought so, her stomach would explode with anger.
Seeing that Zhang San didn't answer, Xie Hua'er gritted her teeth secretly, "Is this girl so unpopular? Humph, I want to stay no matter what I say this time. After all, I have made a guarantee with the master.
"
"I heard that there was a girl named Xiaoyu in our shop who was redeemed by the husband. How about the husband bought me as well? I will definitely serve him well."
"Do you want money? How much? You tell me. Once we receive the money, we will have nothing to do with each other. No, we have nothing to do with each other in the first place." Zhang San felt more and more that this girl didn't look like a good person. She would definitely have trouble getting close to him.
What ulterior purpose.
"You... hum! Do I care about your dirty money? I want to stay here and follow you, can you do that?" Xie Hua'er was so angry that she couldn't believe who she was.
"No, there's no door. If you don't have anything to do, just go back. I have something to do later." Zhang San refused without even thinking. This girl has no good intentions.
"Why, am I not as good as that Xiaoyu?" Xie Hua'er has never been rejected by anyone since she was a child. Everyone around her revolves around her. This Zhang San has rejected her one after another since the first meeting.
I feel like a plague god.
"There is no reason. I don't know you. Why should I keep you at home? Besides, there is no comparison between you and Xiaoyu. She is my family." Zhang San replied unceremoniously.
"I'm so mad at this girl, ah... I won't leave, what can you do to me?" Xie Hua'er immediately acted like a rogue.
"Then I'll just ask someone to take you out, Aunt Li, Aunt Song..."
Seeing that Zhang San really asked people to take her out, Xie Huaer was speechless for a moment.
Aunt Li and Aunt Song came over after hearing the news. After hearing Zhang San's instructions, they looked at each other and prepared to take the girl out.
"Slow down, wait a minute, doesn't your commune make sugar? I know a kind of sugar beet can be used to squeeze sugar, which is much better than your wheat..."
Xie Hua'er had already investigated the situation in Zhangjiacun Commune before arriving, and knew that Zhang San and the others said they were making sugar, but in fact they were just making maltose. Because a lot of wheat was used, the cost of the sugar was definitely not low.
Therefore, Xie Hua'er planned to use this to let Zhang San see his own value so that he could stay here.
But after Xie Hua'er came here, especially when she saw Zhang San being so indifferent and wary towards her, she became very angry, and the previous conversation started.
"Wait a minute, did you just say beet?" Zhang Sanyi was very excited when he heard this. The sugar factory is the most profitable one in the commune now, but the raw materials require wheat, which greatly increases the cost and restricts the sugar factory's production capacity.
It has grown stronger, and maltose is not as sweet as real white sugar. With beets, Zhang San can make white sugar, brown sugar, rock sugar and other different types of sugar.
"Yes, you know?" Xie Hua'er looked at Zhang San's expression and seemed to know about sugar beets.
"Of course I know. Where can I find beets? As long as you tell me, I will consider keeping you here." Zhang San replied.
Based on past experience, sugar beets seem to be grown only in Heilongjiang, Xinjiang, and Inner Mongolia. It is not easy to get to those places in this era.
"Hmph! If you want to know, please beg me. Maybe I will be merciful..."
Before Xie Hua'er could finish feeling proud, she heard Zhang San say: "Aunt Song, Sister-in-law Li, please pull her out!"
"Hey! You... wait, you can't do this, I said." Seeing that Zhang San even wanted to drive her away, Xie Hua'er suddenly became angry.
"Tell me! In fact, I know even if you don't tell me, but I don't have time to go there now. If you have beet seeds that you can give to me, I will let you live here. Also, how do you know that beets can be used to make sugar?"
In fact, this is what Zhang San is more interested in, because beet sugar production seems to have only appeared in modern times. The first beet sugar factory seemed to be established in Germany in 1802.
"You can make sugar from wheat, and you can definitely make sugar from beet, which has a sweet taste. I guess I can give you the seeds, but not now. I can't give them to you until I settle down here, otherwise what happens?
Are you going to kick me out after you get the seeds?" Xie Hua'er gritted her teeth with hatred as she said this. This was the first time that a man kicked her out of the house.
"Okay, but I want to tell you in advance, don't play any tricks or do anything bad to this family, otherwise... I will make you regret it for the rest of your life." Zhang San warned.
"Well, I wouldn't be unfavorable to you in the first place, so why are you being so fierce?" Xie Hua'er said with a pout.
