The next day, Duan Hongxuan went to spend some time with the deaf old lady in the morning as usual.
He Yuyu also ran over and chatted with the deaf old lady for a while, and then ran back to her original room to flip through her elementary school textbooks.
After lunch and a short rest, He Yuyu went to Lou's house to continue teaching, while Duan Hongxuan was alone at home thinking about things after school started.
In fact, Duan Hongxuan has already completed college courses. Every night, he will study for two hours under the intensive indoctrination teaching method of the system steward.
These two hours of study are equivalent to the efficiency of others studying for half a year.
Duan Hongxuan's current level in mechanics, physics, materials, and electronics can be said to be a top expert in this era, far exceeding that of university professors.
But he needs to get a college diploma, so he still has to go to school.
The problem now is that Duan Hongxuan hopes that his abilities in mechanics, physics, materials, and electronics can be recognized in college.
But the major he applied for was mechanical, so he needed to find a way.
Because Duan Hongxuan has actually completed his studies in these fields, he does not want to waste time. It is best if he does not need to sit in the classroom like other students during college, but can participate in specific practical work. p>
This also requires him to think of ways to gain recognition from the school.
In the development of national industry, materials science actually accounts for a large proportion, followed by mechanical machine tools.
A lot of equipment cannot be produced because the materials are not up to standard, or the quality of the products produced is not good.
It's a very simple tool used in lathe processing. Because of the material, other people's tools can be used for a long time, but your tool will be scrapped after less than half the service life of others.
Processing a large workpiece can be completed in one go using other people's tools.
If you use yours, you will need to change the tool after less than half of the processing.
Some workpieces must be processed in one go, otherwise the processing accuracy will be affected or simply scrapped, so you must buy imported tools.
But even if you have to spend a lot of money to buy imported products, they are not necessarily the best. Even if you are rich, others will not sell the best products to you, just to keep you stuck.
And so on, because of materials, we have many constraints in various aspects of industrial development, so Duan Hongxuan has instilled a lot of material knowledge.
In fact, due to the existence of the system butler, Duan Hongxuan can now come up with a variety of high-performance materials that far exceed those of this era.
But if you pull it out of thin air and you don’t have this knowledge yourself, you can’t justify it.
This is also the reason why Duan Hongxuan needs to have knowledge of materials.
The same is true for other machinery, electronics, etc.
It was almost dinner time, and He Yuyu came back early.
In the past, she would be left by the Lou family to finish dinner, but now since Qin Huairu's teaching would begin after dinner, He Yuyu went home early to prepare.
About half an hour after the meal, Qin Huairu came with Xiaodang, followed by a shameless fool.
It was not yet dark, and as soon as Qin Huairu entered the courtyard, she was full of praise for the exquisite scenery of the small courtyard.
After Duan Hongxuan arranged for them to sit under the grape trellis and made some tea, He Yuyu also made a cup of iced sour plum soup for Xiaodang. Xiaodang liked the cold, sour and sweet taste.
Qin Huairu sat under the grape trellis, looking at the scenery in the courtyard, the envy in her eyes almost flowed out!
Silly Zhu lay down on the recliner carelessly and said, "Hongxuan, every time I come back to your place, I don't want to go back because you are so comfortable.
You kid really knows how to enjoy it!"
"Brother Zhuzi comes here often if he likes it. It's so close and you can reach it just by raising your feet.
Brother Zhuzhu doesn’t have a banquet today?”
"How can we have it every day! If there was a banquet to be made every day, that wouldn't be awesome!
On average, there are only one or two times a week, which is pretty good!"
Duan Hongxuan exclaimed: "Brother Zhuzi is amazing! In the past month, the extra income from making banquets alone is higher than your salary, not counting the ingredients I bring back every time.
This cook is always in need of a mouth!"
Silly Zhu was very proud: "That's right, the cook will still be hungry in the lean years!
What's more, if you go out and inquire about my skills, they are famous in the steel rolling mill area!
As long as I don’t do this, it will be someone else’s turn!"
"Brother, you are making so much money now, why don't you give me more every month?"
Silly Zhu was feeling proud, so He Yuyu gave him a sap.
“I’ve given you five yuan every month and you’re still not satisfied!
Now you have room and board here at Hongxuan, and you don’t have to spend any money on food, clothing, housing, and transportation. These five yuan are your usual pocket money, which is enough!
In the whole alley, even in the whole street, no one has even five yuan in pocket money!"
He has worked so hard to earn money. This money is of great use. How can he be plundered by his sister?
"Hmph! I knew it would be like this!
I have to pay tuition, buy books, study materials, and study supplies, and it costs nothing!
Forget it, I’m not counting on you anyway, I would have starved to death if I counted on you!”
He Yuyu is full of energy!
This was in front of Qin Huairu, and Shazhu was a little embarrassed.
I want to get angry, but I really ignored my sister before.
Although he brings lunch boxes back from the canteen every day, He Yuyu doesn't have a share in it at all. It is a fact that He Yuyu often goes hungry.
"Okay, the rain is a thing of the past, why don't we hold on to it!
Brother Zhuzhu, are you going to study with them for a while, or are you going to make them midnight snacks?"
Duan Hongxuan helped smooth things over and changed the topic. Silly Zhu hurried down the slope and said, "I won't get involved with them. I will be responsible for making supper in a while. You have to prepare the ingredients!"
"No problem, the ingredients are all ready-made.
Rainwater and I won’t eat it. It’s up to you whether you want to eat it or not!
It’s not suitable to eat too much at night. Just cook some white porridge, stir-fry pork, and steam some eggs to make egg custard. I think it’s almost done!
The study time is divided into two parts, study for a while and then eat.
After eating, take a break and then study again.”
"Okay, as long as you have the ingredients, I'll have no problem!"
"Hongxuan, thank you! Xiaodang didn't have enough to eat today, so I shamelessly brought her here.
Thank you so much!"
Qin Huairu thanked Duan Hongxuan with tears in her eyes.
"You're welcome, Sister Qin. Xiaodang can eat as much as she wants at such an old age. Don't say anything shameless in the future.
Xiaodang, are you hungry?"
Xiaodang looked at Qin Huairu, swallowed, nodded and said: "Hungry! Xiaodang wasn't full, so grandma wouldn't let Xiaodang eat, and only gave it to her and her brother!
Mom eats a lot before she is a kid!"
After hearing what Xiaodang said, Qin Huairu burst into tears again.
Silly Zhu was so angry that he cursed Jia Zhang, and then stood up: "I'm going to cook now!"
He Yuyu was also very angry and comforted Qin Huairu.
"Xiao Dang, Uncle Xiucai will give you an apple to cushion your stomach first. Uncle Zhuzhu will make meat and eggs for you. Later, you and your mother will eat meat and eggs, okay?"
Xiaodang swallowed and nodded desperately: "Okay!"
Duan Hongxuan went to wash an apple, cut one-third of it for Xiaodang, and gave the other half to Qin Huairu.
Qin Huairu looked at her daughter who was eating an apple sweetly, with red eyes: "I don't know whether my life is bad or good!
Call it a good life, I have such a mother-in-law at home; call it a hard life, we two can meet the old lady and Hongxuan, and you will do everything for us!"
He Yuyu comforted him from the side: "Sister Qin, don't think so much, just eat the apple first. This apple is very sweet and crispy."
Qin Huairu nodded and silently ate the apple in his hand.
Duan Hongxuan got up and got a wet towel, then came back and handed it to Qin Huairu: "Sister Qin, wipe your face after eating, don't think too much, or your eyes will be swollen from crying."
He Yuyu's eyes suddenly lit up: "Sister Qin, eat quickly. After you finish eating, I will take you to take a bath."
"Ah! Take a shower? Now?" Qin Huairu was confused by He Yuyu's sudden suggestion.
"I'm pregnant, so it's inconvenient to go to the bathhouse! Why don't you go by yourself, Sister Qin can't accompany you!"
"Haha! Sister Qin, you misunderstood. You don't have to go to the bathhouse. You can take a bath in this courtyard, which is very convenient!
I have to wash it every day now!"
"Ah! Can you still take a bath in your courtyard?"
Qin Huairu was shocked again.
Nowadays, we usually go to public baths or factory bathhouses to take a shower, and even use the toilet in the public toilet in the alley outside the yard.
Public toilets in this era had a large cesspool that would be cleaned regularly.
In summer, you have to endure mosquitoes and flies, and the weather is hot. The smell is definitely a serious test for your sense of taste!
The weather is cold in winter, and you have to endure the cold wind. The wind blows your butt, which is no longer considered cold. It can be said to freeze to death!
