A powerful country in scientific research

In the afternoon, Jiangshui Brigade, Jiang Fusheng’s home.

Su Ran held a structural diagram of a kang that he had drawn himself and explained to a group of workers the steps of building a kang.

Su Ran: "Repairing a kang is very similar to repairing a house in many ways, but some people know how to repair a house and some don't. So I have to start from the beginning, so if you know how to repair a house, just listen casually."

Although Su Ran was just a little girl under 20 years old, she was the only person in Jiangshui Brigade and even in the entire Hai City who had been praised personally by the No. 1 leader. No one in the team disobeyed her, so they had no objection to being taught by a little girl and even felt very proud.

Su Ran picked up a piece of soil and rubbed it. "When we build a kang, we must first choose the right soil. When choosing soil, we must choose relatively fine soil, so that the kang surface can be relatively flat."

She focused on explaining the setting of the flue. She pointed to the flue in the picture and patiently explained the details and things that need attention.

"There are two most important things when building a kang. One is that the surface must be well made, just like repairing a house, it must be beautiful and without any potholes. The other is that the flue must be well made. The design of the flue and the placement of the partitions must be foolproof. If the kang is well built, the room will be warm and there will be no ash at home. If it is not well built, it will be easy to get cold on the east side and hot on the west side. In serious cases, the smoke cannot be exhausted and it is easy to choke people. So, building a kang is also a technical job."

"The flue should be set in the center of the kang to ensure that the smoke is discharged smoothly and to avoid smoke backflow. The size of the flue should be determined according to the size of the stove mouth. The diameter of the flue should be large enough to avoid blockage. When setting up the flue, an inspection port should also be left to facilitate cleaning of the flue later."

The workers gathered around her, listened carefully to her explanation, and nodded from time to time to show their understanding.

Wang Shan learned the skill of repairing houses from his father. Since he learned it, he has helped repair houses for more than 30 years. He can be considered an old craftsman, but he still listens very carefully.

Su Ran: "Okay, now let's start laying the foundation and building the kang. You must pay attention to the size and placement of each piece of soil, and make sure the kang surface is flat without any bumps or bumps."

After saying that, she took the tools and went to her great-grandmother and great-grandfather's house. They had vacated the house in the morning, which made it convenient for them to work.

The workers began to work according to the steps she said, some pounding the loess, and some stacking the adobe into the shape of a kang. Su Ran kept walking back and forth, checking every detail, pointing out their mistakes, and praising their progress.

Time passed by minute by minute, and the sun had slowly climbed to the west. Wang Shan and his men had repaired the kangs in the three rooms to the kang body part. The rest had to wait until they were dry before they could continue.

Su Ran wiped his sweat, nodded with satisfaction and said, "Okay, let's stop here for today. Tomorrow afternoon, I will teach you how to build a brick kang. We will continue after this is dry."

"it is good."

"Row!"

Wang Shan and others were also very satisfied with the results of this afternoon. They stood up and thanked Su Ran together. Although many of them had rich experience in building adobe houses, they had to admit that they had gained a lot this afternoon.

After the workers left, Su Ran said goodbye to his uncle and aunt and returned home.

When Su Ran got home, Grandma Jiang and Great Grandma were preparing dinner in the kitchen, and Grandpa Jiang, Great Grandpa, and Brother Yunhai were chatting in the side room. As for how Su Ran knew, it was because they spoke so loudly that Su Ran heard it in the yard.

She walked into the kitchen and greeted the two elders who were busy with work with a smile.

"Grandma, great-grandma, what delicious food do you want to eat today?"

Great grandmother smiled and said, "Ranran is back, let's eat hotpot today."

Su Ran's eyes lit up. She had been in this world for so long, but she had never eaten hot pot before! ! She was craving it just thinking about it.

She said excitedly: "Okay, do you need my help?"

Great grandmother waved her hand and said, "No, no, it will be ready soon. Go and have a rest. You've been busy all day."

Grandma Jiang echoed, "Yes, we have almost prepared everything. You can take a rest. We will have dinner soon."

Su Ran nodded obediently, "Okay, then I'll go wash my face." After being covered in dust all afternoon, she felt that she must be covered in dust at the moment.

After washing her face, Su Ran returned to her room. Grandma Jiang had already lit the kang in her room, making the whole room warm.

Su Ran changed out of the clothes she wore for work in the afternoon, put on a set of home clothes, and lay comfortably on the kang.

This kang is such a good thing!

Tomorrow she has to hurry up and build the kang in her grandparents' room, otherwise it will be too cold! Alas, she originally wanted to experiment in her own room, thinking that if it was successful, she would build one in her grandparents' room the next day. Unexpectedly, she was busy with the adobe kang and the experimental field greenhouse, and it has been delayed until now.

She was embarrassed to live in a warm room by herself while her grandparents were suffering from the cold, so when the temperature dropped a few days ago, she asked her grandparents to switch rooms and she would live in the room without a kang.

But grandma and grandpa were unwilling to do so, no matter how she persuaded them. Later, she compromised and no longer insisted on changing rooms. This time, she just wanted people to come over, that is, to let grandma and grandpa come and live with her. Unfortunately, grandpa was unwilling, saying that she was a grown-up girl and had to avoid suspicion. But fortunately, grandma moved in and lived with her.

After we finish building the kang tomorrow, grandma and grandpa will be able to live in a warm house together~~

Thinking of this, Su Ran is happy~~

As she was rolling around happily on the kang, she heard Grandma Jiang calling her outside.

"Of course, of course, come out for dinner."

Su Ran hurriedly shouted outside, "I'm coming, I'm coming." After that, she put on a thick coat and went out of the house.

As soon as she came out, Su Ran saw Grandma Jiang, Grandpa Jiang, Great Grandma, Great Grandpa and cousin Jiang Yunhai sitting at the dining table. There were many rich ingredients on the table, as well as Grandma Jiang's homemade clear soup base and dipping sauce, which made people salivate.

When the great grandfather saw Su Ran coming out, he waved at her and said, "Ran Ran is here, please sit down and come and eat."

Su Ran raised the corner of his lips, "Okay, Grandpa."

There was a seat next to Grandma Jiang, so Su Ran walked over and sat down. She picked up the bowl and put some sesame paste and other seasonings in it.

"Come, try this mutton!" Grandma Jiang picked up a piece of mutton and put it into Su Ran's bowl.

Su Ran took the bowl, tasted it in small sips, and smiled slightly, "Delicious!"

Grandma nodded proudly, "This was brought by your great-grandma. She bought it specially at the supply and marketing cooperative."

Su Ran turned to look at her great-grandmother and said with a smile, "Great-grandmother, this meat is really delicious! But don't spend money next time, it's too expensive!"

Great grandma smiled and said, "Not much. If we talk about spending money, your vegetables are more valuable. It's all thanks to you that we can eat such fresh vegetables in such a cold day. Ranran, don't be polite to great grandma."

Grandfather: "Yes, vegetables are more expensive than meat now. This greenhouse is really a good thing. Ranran, well done, you have developed such a good thing that benefits the country and the people!"

Su Ran smiled embarrassedly, he was praised again!

The atmosphere at the table gradually became lively, everyone passed food to each other, chatted and laughed.
