The time for the college entrance examination is getting closer and closer, and the atmosphere of the graduating class is becoming more and more tense.

Because of SARS, students have not been home for nearly two months, and the pungent smell of disinfectant water is everywhere in the classrooms, dormitories, and canteens, and they have to undergo temperature measurements from time to time, and the students' mood is inevitably very depressed.

In particular, I saw from the TV in the cafeteria that six suspected cases who had returned home from working in the south were intercepted and quarantined in the urban area, and many of the students whose homes were nearby were a little distracted.

The school has tried to arrange more teachers to calm the students' emotions, and at the same time, it has also strengthened management, and parents are no longer allowed to visit students at the school gate.

Now parents who come to the school will be received by the teachers on duty at the school gate, explain the situation one by one and let them leave, and the items they bring will be registered one by one, disinfected and then handed over to the students.

Standing in the hallway outside the classroom, Chen Qiaoshan can often see security guards patrolling back and forth outside the school walls.

Recently, Yan Xiaoqin has been under a lot of psychological pressure, and the whole person seems worried.

After getting along for a while, Chen Qiaoshan also probably understood the situation of her family, her father worked in the city government department, her mother was a doctor in the city hospital, and the whole family lived in the city.

In today's unclear SARS epidemic, civil servants and doctors are the two most dangerous professions, and when it is most dangerous, others can still huddle at home, silently waiting for the end of the epidemic, but doctors and civil servants are always on the front line of the battle, which is a fact that everyone can see.

A few days ago, Chen Qiaoshan also saw the future prime minister from the newspaper column, and now he is the number one leader in Henan Province, and he still looks very young when he looks at the photos in the newspapers, and he is going around to comfort the medical workers who are fighting on the front line, and Chen Qiaoshan's heart is also quite emotional.

Yan Xiaoqin was very worried about the safety of his parents, and he could only stay by her side to try to calm her emotions.

After dinner, Chen Qiaoshan accompanied her for a walk around the campus, hoping to relieve her tension.

He has nothing to worry about because he knows that there is no safer place at this stage than school.

Parents and little sister are in the countryside, it is a remote village at the junction of Hubei and Henan, there is no floating population near the village except for barren mountains and fields, there is only a tattered asphalt road from the city to the town, although there is also a Jiaozhi railway through the state and county across the east and west, but unfortunately the station is also far away fifty miles away.

Chen Qiaoshan thought about whether to contact his family, and after thinking about it carefully, forget it.

The Chen family did not install a phone, and usually wanted to contact the second uncle's family half a mile away, running back and forth to shout that the family was too troublesome, and there was usually nothing to do, and the brother and sister generally would not call back.

Chen Qiaoshan thought about whether to go and see Chen Xi, people in the school have been panicking in the past few days, and he should also fulfill his obligation to be an elder brother.

"What are you thinking?" Yan Xiaoqin suddenly asked.

"Nothing. Chen Qiaoshan didn't tell her what he thought, he thought about it and said, "I'm thinking about the future when we go to college together!"

"Who's going to college with you. Yan Xiaoqin said angrily, but her expression relaxed, as if she was also thinking about strolling around the university campus with Chen Qiaoshan in the future.

Chen Qiaoshan breathed a sigh of relief, it was also a good way to divert his attention.

The students who took the college entrance examination this year were really unlucky, and the first time they changed the exam to June and encountered SARS.

He clearly remembered that in the past few days, it was the most serious time of the epidemic in the country, and Yanjing and Hong Kong at this time should be the time when the confirmed cases of SARS broke out, and it is estimated that the government is also busy.

Of course, the climax is here, and it is not far from the end, on the 24th of next month, Yanjing will lift the travel warning, but it will not be until June 24 next year that the World Health Organization announced the lifting of Yanjing's travel ban, during which there have been several suspected cases, but fortunately, they are all false alarms.

Chen Qiaoshan was also a little glad in his heart, fortunately he didn't travel to Yanjing, otherwise he would have to live in fear all day long, and he didn't know how his sister who had never met in Yanjing was doing now.

However, his happiness did not last long, due to the recent severe epidemic situation, the school has strengthened the monitoring of students, and before dinner, the school doctor checked several classes in the second year of high school, and found several students with abnormal body temperatures.

The news spread throughout the campus during dinner, and Chen Qiaoshan did not hear the news from Sun Guangming until he studied last night.

What is the situation, it shouldn't be.

In Chen Qiaoshan's memory, he clearly remembers the process of the SARS epidemic in 2003, except for the elevator infection incident of Northern Jiaotong University, there was no outbreak of the epidemic in other schools at all, and there were only a few sporadic cases in Henan Province.

Thinking of this, Chen Qiaoshan shuddered a little, if history really changed, what should he do?

The reason why this period of time is so calm is that he knows the trend of social development in the next ten years, and if history changes, he still has something to rely on.

After a while, Chen Qiaoshan calmed down.

He can come here inexplicably, what is it to change history, the life experience of the two lives is his greatest wealth.

In his subconscious, he came here to change history, and so far the news has not been confirmed, spring is supposed to be the flu season, what the result is still unknown, and now it is not even a suspected case.

Chen Qiaoshan pondered what he could do now.

Chen Qiaoshan, who has experienced the popularization of various public safety knowledge on Weibo and WeChat in later generations, knows better than most people how to better strengthen self-protection in this crisis.

He knew that SARS was transmitted through close-range airborne droplets, and the most important thing to do now was to avoid too much contact with the outside world as much as possible, and it would be nice if he could get a few masks.

Thinking of this, Chen Qiaoshan and Sun Guangming muttered quietly for a while, and then the two sneaked out of the back door.

Out of the teaching building, Sun Guangming asked: "Dashan, is what you said reliable, is it really safe to wear a mask?"

Chen Qiaoshan said affirmatively: "Now is not a question of unreliability, now is the most important thing for safety, no matter whether it is reliable or not, you have to get some back." ”

"Where are we going to get it? Are we going to buy it in the supermarket?"

Chen Qiaoshan couldn't help but roll his eyes, in the absence of large-scale popularization of public health and safety knowledge, people have not yet developed the habit of wearing masks when they go out, there is no market if there is no demand, and there will be no supermarket to sell masks.

Chen Qiaoshan knew that it was not until after SARS that masks were gradually known by the public and became one of the necessary protective equipment for home travel.

At this time, masks can protect against the spread of SARS should have spread in Guangnan and Yanjing, and masks must have become a scarce resource, and in the province where he is now, only sporadic cases of infection have been found, which has not attracted enough attention.

Aside from the school doctor, Chen Qiaoshan has not seen anyone wearing masks on campus.

He pondered that he had to think of a way, it was best to make masks popular in schools, regardless of whether SARS existed in schools, so that they could play a certain protective role.

Chen Qiaoshan glanced at Sun Guangming, "Think about it, who usually uses masks in school?"

"You mean let's go to the infirmary and buy it?"

"It's good to go to the infirmary, but it's not necessarily good to buy it. ”

It was evening self-study time, and the campus was quiet, so the two sneaked to the door of the infirmary across the supermarket.

The two looked inside for a while, and there was only one female doctor sitting behind the desk.

Chen Qiaoshan whispered: "I'll go first to see the situation, you stay outside, be careful not to let people notice you." ”

The doctor was wearing a gauze mask, and her eyes were tightly covered, and Chen Qiaoshan couldn't see her appearance clearly.

Seeing Chen Qiaoshan coming in, the female doctor asked, "Where are you uncomfortable?"

Hearing the female doctor's voice, Chen Qiaoshan took a closer look at her appearance, thinking that she shouldn't be very old, "Doctor, I'm not uncomfortable, I just want to ask you if you have masks here?"

"Why do you ask this?"

Chen Qiaoshan said: "Many people in the school have fevers, and I want to buy a few masks, and it should be safe to wear them." “

The young woman listened to her words for a moment, and then said, "It's true that there are masks here, but masks are not sold here, and the masks are all for doctors, and there is no way to give them to you." ”

Chen Qiaoshan didn't say much when he heard it, nodded and walked out, but made the female doctor stunned, originally she thought that Chen Qiaoshan would ink for a while, thinking that if it didn't work, she would give him a pair, but she didn't expect that as soon as he said that he wouldn't sell it, he would leave directly, which made her a little inexplicable.

As soon as Chen Qiaoshan came out of the door of the infirmary, he saw Sun Guangming sneakily hiding at the door, this kid must have been hiding here just now to eavesdrop on the conversation inside.

Seeing him come out, Sun Guangming asked: "What should I do now, people don't sell it, what are we going to do now?"

Chen Qiaoshan smiled and said, "Of course it's to buy masks! Let's go to the supermarket." After that, he walked to the supermarket opposite.
