Siheyuan: From a technical secondary school student to an academician of a major country

Chapter 44 Three Highs
Waste recycling station.

Yu Wenzhen came here.

Today he plans to find some broken radios and parts, as well as some materials for experiments.

In those days when there was no Internet, computers, or mobile phones, the only thing I did at night was reading or sleeping, which was really boring.

So Yu Wenzhen thought of the radio.

But radio tickets were equally hard to come by, so he could only start with second-hand ones.

As for the materials, he planned to use them for battery research.

It is not the kind of battery that can be charged and store electricity, but a small, cylindrical battery similar to the Nanfu battery.

When he made this radio, he also had the idea of ​​converting it to battery power, which would not only spice up his life, but could also be used to test batteries, which was simply perfect.

After some picking and choosing, a pile of waste was soon picked out.

After paying the bill and bringing his things back to the compound, Yu Wenzhen went straight into his room. He didn't come out until lunch was ready and Lu Shuqin came to call for help.

"Wen Zheng, the factory will resume work tomorrow, remember to go to the factory the day after tomorrow."

When Yi Zhonghai saw Yu Wenzhen coming over, he spoke up to remind him.

He himself was afraid that he would forget to remind Yu Wenzhen, so it would be better to tell him in advance. After all, he was old, and his memory was not as good as when he was young.

"Okay, I remember it."

Yu Wenzhen nodded.

Just as one topic was over, Lu Shuqin brought up another one: "Just now I saw you brought back a bunch of waste. What are you busy with?"

Yu Wenzheng casually replied: "I want to get a radio and modify it at the same time."

His answer was light, but it surprised Yi Zhonghai and his wife.

There is a radio at home.

What's the point of using a radio?
"There's already one, why don't you just use it? It's really troublesome to fix a broken one."

Lu Shuqin looked at Yu Wenzhen with annoyance.

"Okay, didn't you hear Wen Zheng say that you want to reform?"

Yi Zhonghai glanced at Lu Shuqin and said, "Let him decide for himself about the child's affairs. You don't understand those things, so don't make things more complicated for him."

"Master, master."

As the three were talking, a hurried voice came from outside the house: "Uncle No. 1, go and have a look, Uncle No. 2 has fainted."

The three people in the room were all stunned.

Second uncle?
I haven't heard of this title of "Second Uncle" for a long time, and I'm a little uncomfortable with it.

Something happened to Liu Haizhong?
After realizing what was happening, Yi Zhonghai threw away the half-eaten steamed bun, hurriedly got up and went out, asked the young man outside the door a few words, and then hurried to the backyard.

"I'll go take a look too."

Yu Wenzhen followed him out with the steamed bun, and ate it as he walked to the backyard, finishing it in just a few bites.

When they arrived at the backyard, the Liu family was in chaos, with many people watching outside the house.

Yi Zhonghai was directing several young men to lift Liu Haizhong onto the cart.

Yu Wenzhen glanced at Liu Haizhong.

His eyes were closed and he was unconscious, his breathing was disordered, and his face and lips were slightly pale.

Through inspection, Yu Wenzhen confirmed in an instant that Liu Haizhong should be suffering from high blood pressure.

However, although he saw it, Yu Wenzhen did not go up to treat Liu Haizhong.

Although he has medical skills, he is too young and not many people in the hospital know that he has medical skills.

He knew the character of the people in the hospital very well, and he didn't want to let everyone know, because that would be annoying. Besides, he was not a formal doctor, so he must not say that doctors are caring.

Medical skills are not selfish, but people are.

He learned medical skills not for the people in the hospital, but for those close to him, just to take precautions.

Liu Haizhong was quickly sent to the hospital, and the examination results were exactly the same as what Yu Wenzhen had seen.

Hypertension caused the fainting, but fortunately there was no shock and the patient was sent to the hospital in time, so there is no serious problem.

Seeing that Liu Haizhong was fine, Yi Zhonghai took everyone in the courtyard back to the compound, leaving only Ge Shaofang, Liu Guangtian and Liu Guangfu.

Something happened to Liu Haizhong, and people in the hospital had a new topic of conversation.

It was mainly those who were unaware of the situation and did not go to the hospital. If Yi Zhonghai and others had not returned in time and brought back the test results, I'm afraid rumors would have spread throughout the hospital again.

When Yi Zhonghai returned home, Yu Wenzhen was chatting with Lu Shuqin. Seeing that he was silent, he asked him a question.

Yi Zhonghai sighed, "Old Liu looked very strong, but I didn't expect him to fall ill."

The figure of the man with the bangs can be considered strong in this era. Many people want to have such a figure but cannot achieve it by eating.

Being plump and having plenty of meat is a sign of a good life for people of this era.

They don’t have any concept of the three highs nowadays. They all think that being fat is a sign of a prosperous family with plenty of oil and water.

"Uncle, Master Liu's physique is not strong, but fat."

Yu Wenzheng shook his head, knowing that the two elders didn't understand this, so he explained: "Obesity can easily cause three highs: high blood pressure, high blood lipids, and high blood sugar."

"If young people have these three highs, it's not a big deal. Exercising more can always lower them. But it's different for the elderly. If they are not controlled with medication, it can easily lead to various diseases. So obesity is not a good thing."

"In addition, it's not just fat people who have the three highs. Elderly people generally have symptoms of high blood pressure, which is something we need to pay attention to."

Seeing how Yu Wenzhen spoke so logically and considering his medical skills, Yi Zhonghai had to believe that this was true.

Yi Zhonghai was frightened and asked quickly: "Is there any way to avoid it?"

"Don't worry, I'm at home, right?"

Yu Wenzheng pointed at himself and said with a smile: "With a professional doctor like me here, any problem you have would have been solved long ago."

Suddenly, Yu Wenzhen felt that Liu Haizhong's illness was not a bad thing. It could make his parents pay more attention to their health, and he would feel more at ease when going to school.

Yi Zhonghai nodded and said jokingly: "I forgot that we have a master with excellent medical skills."

"Please don't, please don't spread the fact that I know medical skills, or I'll be annoyed to death."

Yu Wenzhen doesn't dare to admit the title of medical master. Compared with dealing with trivial illnesses in the hospital, he prefers scientific research.

He has a learning system. Even if he develops in the field of medicine in the future, he will study medicine, and his research and development direction will definitely be various special-effect drugs.

Common minor illnesses were not even within his consideration.

After chatting with the two elders for a while, Yu Wenzhen went back to the house to continue working on the batteries.

In fact, batteries have existed for a long time. Today’s flashlights also use batteries, but their storage capacity is not large and their cost is very high.

A battery costs ten dollars and an industrial invoice, which is really outrageously expensive.

The battery that Yu Wenzhen is going to study must have a large storage capacity. It must be able to power the radio for at least two hours of normal operation.

Another thing is that the cost has to be low. The current battery price is too high, and we have to bring it down.
