Writing a paper is a very boring and boring thing.

Since this was Shen Guanglin's own project, and it was a groundbreaking paper without precedent, it was even more difficult to write.

Anyway, time is not urgent, Shen Guanglin also writes while following Li Rong in class, just to change his mind.

Entering December, the weather became colder with the first snow of the winter of 1980.

Shen Guanglin was not a person who was afraid of the cold. At this time, he had to shrink his neck and put his hands in his sleeves, trying to maintain a little warmth.

Nowadays, it’s painful to go to class, and you have to stamp your feet while giving lectures.

There are so many people in the classroom, so it's not supposed to be cold, but there's no way to prevent drafts.

This kind of traditional small glass window provides good lighting, but it is not frost-resistant, air leaks crazy through the gaps after the deformation of the wooden pane, and the heat insulation of the single-layer glass is extremely poor.

I don’t know how these children survived the winters.

The conditions in the laboratory are good, the heating is sufficient, and a little coal can make everyone feel warm, and there is also hot water.

Shen Guanglin doesn't care what happens to others. The class he attends will have someone prepare a briquette stove in advance.

With a kettle on top, everyone can drink some boiled water, which is considered a student benefit.

The cost is not much.

There is no English teaching this semester, and there are only three classrooms where Shen Guanglin teaches. He paid for it personally.

Burning briquettes for heating is very economical. A stove requires about 5 briquettes a day, and each briquette costs only 5 cents. The total expenditure per day is only 75 cents, which is only more than 20 yuan a month.

Shen Guanglin directly gave 100 yuan to each class. The extra money was counted as class fees, and he could buy some sweet potato buns and other snacks for the students.

However, this also caused his class to be so popular that he had to endure hunger and cold to go to other classes.

It's warm in the classroom where I teach, but the classroom in the National People's Congress is still as cold as ever.

Shen Guanglin sometimes accompanies Li Rong to classes, and he can't help but feel sleepy when he hears some economic and political courses. But now, the weather is too cold, and even sleeping is difficult.

The classrooms at Renmin University are even more dilapidated than those at Beijing University.

Boys basically rely on shivering to stay warm.

Girls have another idea. They use a glass bottle with a rubber stopper to fill a bottle of hot water to warm their belly.

That kind of bottle is very strange. It is used to sell milk and it seems to be used for injection and infusion.

Holding it in my arms, sitting there I felt like every female classmate was a pregnant woman.

Li Rong's treatment is better, she has a traditional hot water bottle.

It is a flat bag made of something like rubber. The mouth of the bag is a rotatable stopper. This bag can be used for a longer period of time, but it looks more like a pregnant woman when placed in the arms.

Shen Guanglin decided to make her a modern hot water bottle that could be heated by charging.

In fact, the ingredients are very simple, consisting of water, iron powder and ferrite. A heating resistor is placed on the charging plug, and some circuit devices are added.

Charge for five minutes and keep warm for 5 hours.

Just when everyone was thinking of various ways to keep out the cold, the poor woman with the child came to the school crying.

Something happened to Lai Hongmei again.

"Clothing Beauty" Jiang Zhenhua has a serious job and a lot of savings, so she doesn't set up a stall anymore.

The main reason why I didn't set up a stall was because it was too cold and I really couldn't stand being outside for a few hours.

Another important reason is that work is really busy.

There are now more than a dozen people in the laboratory, and she is in charge of everyone's food, drink, and toilet. Although Sister Zhao does the big finance, she is the cashier.

The things you need to buy need to be in place immediately, and there is really no time to set up a stall.

However, the prime spot in the garage on the first floor that Shen Guanglin helped her find couldn't be left unused, so she pulled Lai Hongmei over.

She was in charge of the venue and Lai Hongmei was in charge of the show. It was considered a joint operation between the two of them.

Jiang Zhenhua only pays dividends and occasionally helps out.

Some people are born with economic acumen. Jiang Zhenhua came to Beijing for a few months and earned between 7,800 and 8,000 yuan, close to tens of thousands of yuan.

She didn't save any money even though she had money. Apart from mailing some money to her family, she bought two shops for herself with the rest.

Although the location is not on Xiushui Street, it is a street-facing shop near Wudaokou, and can be used for accommodation or a shop.

Of course, she also followed Shen Guanglin's advice, since her uncle would not harm him anyway.

The same cannot be said for Lai Hongmei. She works very hard selling clothes, but her sales are not as good as Xiao Jiang's.

Moreover, she had never thought about buying a residence in the capital and settling down. She had been living in the compound Shen Guanglin bought.

The weather was cold, and after moving the stall to the garage, the conditions were indeed much better, but the money she earned by herself had to be divided between two people, which made her feel very uncomfortable.

Last week, the two of them had a quarrel over the issue of dividends.

Despite Jiang Zhenhua's Wenjing appearance, he is not timid: "If you don't want to do it, just move away. I have many people here who are willing to use it. I provide the supply of goods and the venue. Not to mention 50%, but 60% to 70%, there are people rushing to do it. "

Jiang Zhenhua is Teacher Shen's niece, and Lai Hongmei is just an outsider.

Shen Guanglin found this garage for Jiang Zhenhua, and Lai Hongmei had no choice.

Lai Hongmei has been in the capital for half a year, and her accumulated profits totaled several thousand yuan. Fortunately, this time, all of them were stolen.

All the clothes temporarily stored in the garage were also swept away. In addition to the money missing from the residence, the loss was less than 10,000 yuan.

It seems that any kind of business is not easy.

Lai Hongmei was quite depressed when she found her. Her hair was disheveled, her hands were as cold as carrots, and her face was chapped red. She must have been reluctant to buy cosmetics.

Her daughter must be at school, and she brought her with her. She was dressed in tatters, but her face was rosy.

"Teacher Shen, you have to make the decision for me! I woke up early and worked late at night, and my work for most of the past six months has been in vain! The thief who was killed by God has left nothing for me." The more she cried, the more miserable she became, as if her life in the past six months had been in vain. The conditions have not improved much. Where is the money she earns?

"How do you want me to make the decision?"

The way she cried made Shen Guanglin very annoyed, and he couldn't stand it.

"I don't know, that's half a year's savings, and I haven't even got a penny left!" She couldn't say 123, she was just crying anyway.

"As long as everything is fine. Let's do this. My lab is short of a chef right now. Don't set up a stall. Come over and cook. Take care of food and housing. You'll get your salary every month. It's much better than those of chefs in state-owned units. Already."

The most important thing Shen Guanglin lacks here is jobs, it’s just an extra pair of chopsticks.

Lai Hongmei didn’t want to agree:

"Teacher Shen, there is no need to trouble you. Just lend me the shop on the first floor of Xiushui Street for a while. It's better to rely on yourself. I can ask Brother Shun for some clothes on credit, and I will pay him back when I make money. Zhenhua Didn’t the girl buy the shop herself? She won’t be able to use it here...",

"Last week she asked for some money from me, but the money disappeared before I could bring it to her."

The current security situation is indeed very bad!

Shen Guanglin specifically told Shunzi to take care of the two of them. After all, it is not easy for a woman to raise a child, and he didn't know what Shunzi would do.

However, it is said that Lai Hongmei has been living in the store recently, so why can her home be robbed?
