Reborn in the 70s as a military doctor and meets a special soldier

In the past few decades, the country has been rising rapidly, and development is taking place everywhere.

However, other people can burn funds for development, but we have to work hard to develop. How many people in this generation have exhausted their resources in the process of development?

Not to mention other things, just the railway soldiers digging in these tunnels, pneumoconiosis, respiratory diseases... there are many hidden dangers lurking around them.

As a doctor, knowing that there is a remedy, we naturally have to work hard to remedy the problem, instead of waiting for something to go wrong and then fighting death in the operating room.

Song Wei took Zhang Xiuhui's notebook, scribbling and drawing as she talked, and soon she drew what she thought the dust mask looked like.

Zhang Xiuhui was stunned to see this round of operations.

“Our masks are made of gauze and are too weak for dust protection, so I wanted to make an upgraded version.

Compared with ordinary masks, the biggest difference lies in two points. First, it is equipped with a nose clip to make the sealing better, and it has a replaceable filter cotton core. "

As the name suggests, anyone who has worn a mask knows that the nose clip is the "small wire" across the bridge of the nose. It fits the shape of the person's face better and can achieve the function of sealing a space.

Of course, the nose clip was invented more than ten years later, and current masks do not have this.

Speaking of masks, although they are commonplace, masks have also experienced dark times in the development of our country.

People only think that gauze masks are soft and hygienic, but they don't know that gauze masks cannot prevent dust or germs.

For a long time, gauze masks have exposed doctors and nurses to the risk of infection, and medical workers have paid a heavy price for this.

Speaking of which, didn't Liu Yu die young due to infection?

Of course, leaving aside how to make medical masks, this requires a professional team to develop, and Qingcun cannot complete it.

However, Qingcun can make dust masks.

In Song Wei's idea, the nose clip can be replaced by wire, and the most important part, the replaceable filter element, can also be made of local materials, made of linen and cotton.

The first layer is 1-3 cm thick flax sheets. The flax is hammered into thin sheets and has the same effect as paper. It has better air permeability than paper. It can be used as the first door to block large particles of dust; the second layer is 3-5 cm cotton. The fine texture of cotton can filter fine dust particles.

After finishing the two filter layers, sew them together with a double layer of gauze, and then you can put the mask on and take it off freely.

In fact, the principle is similar to that of women's sanitary pants in this era. Women's sanitary pants are replaced with toilet paper inside, while masks are replaced with filter cotton cores.

After all, this simple version of the mask has a limited service life, and the cotton core needs to be replaced every three to five. The removable and replaceable filter cotton core is the best choice.

Zhang Xiuhui quickly understood the principle and thought about it carefully: "We have flax and cotton here, but we need to do experiments to know whether it can work."

"You have the courage to do it, and I will come and pick it up in two days." Song Wei handed over the task decisively, her tone full of trust.

Zhang Xiuhui was a little flattered. After all, she rejected Song Wei's redemption, thinking that Song Wei would feel that she was spineless and unpromising, but the reality was that Song Wei did not do this, and even gave her such an important task regardless of previous suspicions.

"I thought……"

Zhang Xiuhui was confused as to how to organize her words, and Song Wei smiled: "Do you think I will look down on you and then stay away from you forever?"

Zhang Xiuhui smiled sheepishly.

"In fact, if you choose to stay, life will be much harder than returning to the city. I can't even admire you for having the courage to stay in the village, let alone shouldering the responsibility of the village chief.

Leading Qingcun forward, who am I to look down on you? I should admire you. "

Of course, this is based on the fact that Zhang Xiuhui and Sun Ping have feelings for each other, and her husband's family treats her well.

The experiences of Zhang Xiuhui and Lin Xiangping are completely different, so their choices cannot be compared. What's more, she has two babies and an unborn one in her belly.

Others could pretend that nothing happened and go back to the city to remarry. But if she returned to the city with a big belly, others would just think that she was pregnant out of wedlock and was being discriminated against.

Song Wei was not an unreasonable person, and she also understood Zhang Xiuhui's helplessness.

Upon receiving understanding, Zhang Xiuhui's eyes showed real relief: "I will definitely do my best to change the ignorant status quo of this village and create a better future for my children."

Song Wei nodded and left with Dongzi.

On the way back, Dongzi sighed with emotion: "Dr. Song, this mask you are going to make feels very powerful.

Song Wei smiled: "We won't know until it's done whether it's powerful or not. After all, it's just talk on paper now."

"Then why don't you keep the overseer? Can they do it without you?"

"I can only provide an opportunity. Whether they can seize it or not depends on them. We have to check everything, so we might as well open our own factory in the Security Department."

Dongzi couldn't help but laugh: "That's true. Dr. Song, you are really amazing. Is there anything else you can't do?"

Will not?

Song Wei was stunned for a moment. Thinking of Lu Jiu, she sighed slightly. Doesn't it count if she doesn't know how to chase men?

Of course, these words could not be said, Song Wei could only smile bitterly.

When the two of them rushed back from Qingcun, someone had already left work in the mine. Taro and the others could not find Song Wei, so they had already started the free clinic. Song Wei didn't say much, washed her hands, rolled up her sleeves, and joined in. It was late at night.

When she returned to the camp, sleepy and hungry, she saw lights in the camp at the security office, and the smell of food filled the surrounding area.

Upon closer inspection, Xie Pai and others were actually there.

Xie Pai and others stayed up most of the night, what could they do if they were gathered around here? You don't need to guess to know that Lu Jiu must be here.

Sure enough, when they got closer, they heard the little soldier from the Railway Corps praising: "Lijun, your barbecue is so delicious!"

"Slow down, don't choke."

"The Army is coming?"

Yanni's eyes lit up when she heard the voice, and she rushed into the crowd. The people who were eating together saw them coming back and quickly made way for them.

The person surrounded by three layers inside and three outside was not Lu Jiu.

At this time, he was roasting a... pig in the campfire.

The pig's head was placed beside it, with black bristles, and the internal organs in a bucket. These were probably reserved for breakfast tomorrow morning.

The pig's head looked like it was no ordinary pig, but a huge wild boar.

The railway soldier next to them had become familiar with them in the past few days, and he chatted familiarly without the need for small talk: "The Army encountered a wild boar on the transportation road. The wild boar blocked the road and crashed into the car without mercy, and was then captured by the Army. "

"So powerful? How did you catch him?" Yanni's eyes widened.
