On this day, as soon as Zhao Weidong arrived in the classroom, he heard his classmates chattering, he just sat down in his seat, and Yan Chuanming, who was now sitting in the fourth row, said to Zhao Weidong:

"Weidong, you know, I heard that the commune epidemic prevention station has asked the school to ask our class to participate in the commune's swine fever epidemic prevention work."

Zhao Weidong asked seriously:

"Already decided?"

"I heard that it has been decided, and I guess this matter will be announced in class today."

Zhao Weidong's memory of the relevant memories also slowly emerged, it turned out that the thing was like this, during this period of time, there were some places where there was an epidemic of swine fever infectious disease, there were more pigs died due to swine fever, and the epidemic situation in various places had a tendency to expand, so the higher-level epidemic prevention department issued an epidemic prevention plan, requiring all possible epidemic transmission areas to carry out comprehensive epidemic prevention, and the vaccination should be hit to every pig, and it should be completed as soon as possible, but there are only two people in the commune epidemic prevention station, It was impossible to complete the sixteen brigades of the whole commune in a short period of time, and in desperation, they turned to the school for help and asked for support.

Sure enough, it was not the teacher who came to the class, but the class teacher who accompanied the principal to the class, first announced to the students the decision to organize the whole class to participate in social practice activities, and at the same time introduced the main content of participating in social activities, and mobilized students to actively participate in this social practice activities and strive to achieve good results in the activities.

After the mobilization, Stationmaster Li of the epidemic prevention station gave the students a short and targeted training.

One is to introduce the epidemic characteristics of swine fever infectious diseases, the serious consequences of infectious disease outbreaks, and the most effective prevention method for swine fever infectious diseases is to inject swine fever vaccine;

The second is to introduce the tools and drugs that need to be used in the activity, the tools used are the syringes, this syringe is not the same as the syringe that the students usually see in the hospital, the syringe we see in the hospital is a glass tube syringe, and the veterinary epidemic prevention syringe has the same function as the hospital, but the veterinary use is mainly in the anti-fall function to strengthen, except for the glass tube for the needle, the rest are all metal, it can be said that it is a metal syringe, and the drugs are two kinds: 1. swine fever vaccine, 2. distilled water. The third is the mastery of the technology used, how to use it, the technical requirements in use, and the injection site behind the ear and so on.

In the afternoon, the whole class used an afternoon to imitate the practice, carry out rapid injection exercises, exchange experience with each other, professionals correct on the spot, after half a day of practice, most of the students basically master the technical essentials, the probability of successful injection should be about eighty percent, due to the tight time, it can only be done to such an extent, tomorrow it must be divided into two groups, each epidemic prevention station personnel with a group, down to the major teams to start the formal epidemic prevention work, and finally require the participating students to have bicycles all brought, Tomorrow morning at 8 o'clock in the morning, we will gather at the gate of the commune epidemic prevention station.

At eight o'clock in the morning the next day, all the students arrived on time, there were seven students with bicycles, some of their own, some were borrowed from others, the epidemic prevention station prepared a tractor, a total of 42 students in the class, because each bicycle two people, with a bicycle group of 20 people, with a tractor group of 22 people, now the bicycle group is short of three bicycles, so the epidemic prevention station to borrow three bicycles, soon Li stationmaster borrowed a bicycle, because the bicycle at this time is the work car of each unit, Each unit has a shared bicycle, and some individuals also have bicycles.

The group using the tractor, after the personnel determined that they set off immediately under the leadership of a staff member of the epidemic prevention station, the second group was combined after the stationmaster Li borrowed the bicycle, because it was two people and a bicycle, Zhao Weidong asked Ye Qianru to give the bicycle to others, so that she could use the same bicycle as herself, after all the arrangements were made, under the leadership of the stationmaster Li of the epidemic prevention station, they rode to Zhangjiatun in a mighty way, and arrived at the Zhangjiatun brigade after more than half an hour.

The captain is waiting for the epidemic prevention station Li stationmaster and other epidemic prevention personnel at the brigade headquarters, after a brief exchange, he took the epidemic prevention personnel of Li stationmaster and his party to start injecting pigs with swine fever vaccine door to door, the first few pigs are injected by Li stationmaster, the students are responsible for preparing injections, and draw them into metal syringes according to the dose, and provide them to stationmaster Li for use, in the injection, stationmaster Li reminded the students to pay attention to the technical essentials, only to see him slowly walked to the side of the pig, at the moment when the pig stopped moving, Lightning-fast metal syringe pierced the back of the pig's ear, the pig felt the stinging pain, and immediately arched its head towards the person, indicating its anger, and immediately pulled it out.

After the injection of a few pigs, the students once again introduced the technical essentials, after on-site observation, the students have an intuitive feeling, the understanding of the technical essentials has deepened, the piercing should be fast, the injection should be fast, the pull out should be fast, to do three fast, if the injection is early, the needle has not been inserted, the potion has been injected out, or the injection is late, the needle has been pulled out, the potion has not been injected in, everyone will operate according to this requirement, Stationmaster Li continued:

"Now, which of you is the first to take the initiative to get the pig vaccination."

"I, I'll come." Classmate Huang Zhangjin took the lead and asked to be the first to get a pig vaccination.

"Very good, you have a lot of courage, the next pig will come to you."

Stationmaster Lee replied, and handed him the metal syringe, reminding:

"This metal syringe has a quantitative injection setting, you have to adjust it after each injection, each injection is 1cc of potion, you have to adjust it on the injection rod, there is a scale on it, you have to adjust it before each injection before the injection. Okay, let's go fight now. ”

Huang Zhangjin walked to the pig pen of the club with a metal syringe, walked to the pig pen and stopped, the pig in the pig pen saw someone coming, and walked to the pig trough, snoring, raising his head high, looking at the people approaching it asking for food, Huang Zhangjin saw the opportunity, and stabbed the pig behind the ear, because the stab was too heavy and too deep, and the reaction was slower, the potion had not been injected in, the pig was angry and angry, and the head shook Huang Zhangjin's hand off, The whole metal syringe hung on the neck behind the pig's ears and shook it, and the pig scurried in the pigsty because of the pain, and then because the pig felt that something in the neck caused it pain, it shook its head vigorously to shake the metal syringe off, and also relieved itself of the pain.

This pig can only continue to be solved by the professional stationmaster Li, I saw that after he waited for the pig to calm down, he quietly approached the pig and completed the injection task in an instant. At this time, most of the students flinched, and Stationmaster Li saw everyone's retreat, if everyone could not play a role, then this time the epidemic prevention task of the whole commune could not be successfully completed, and the fear of difficulties in everyone's hearts must be eliminated, so Stationmaster Li said:

"Don't be afraid, it's normal to make occasional mistakes, and you'll be able to master the essentials of the technique after a few more attempts, who will come next?"

"Stationmaster Li, let me try it now." Zhao Weidong took the initiative to bring it up.

"Okay, it's up to you, be careful not to be nervous, be bold and careful, go ahead."

Zhao Weidong got the metal syringe, he first checked whether the limiting metering device was adjusted in place, whether the tightness of the injection piston was appropriate, and after all were set, he slowly walked into the pigsty, because the pig was frightened just now, both pigs were hiding in the corner, and they could only walk in and drive the pig away from the corner, just when the second pig came out and passed by Zhao Weidong, he quickly inserted the metal syringe into the position behind the pig's ear, and immediately injected all the limited potions into the pig's body, and pulled out the metal syringe before the pig began to react. Perfectly complete the task of injecting anti-epidemic drugs.

"Students, you see, this classmate, the timing of the choice is appropriate, the injection position is accurate, and the entire injection technique is completed cleanly and successfully, which is exactly what you do." Stationmaster Li immediately affirmed and praised Zhao Weidong's actions, which enhanced the students' confidence in vaccination.

After a day of practice, each of the students mastered the skills of injection, or the learning effect in practice is good, of course, there are a lot of foreign appearances in practice, some metal syringes have not been inserted, and the potion is sprayed on the pig's body, which is considered to be a medicated bath for the pig; Some metal syringes were not only inserted in, but also pulled out smoothly, but at first glance, the anti-epidemic medicine was not injected in; Others forgot to adjust the limited screws after the limited injection device was used up once, and no potion was injected into it; Some picked up the metal syringe and were about to pierce the back of the pig's neck, but due to poor timing, the pig's head turned to the needle, touched the hand that pierced the needle, and touched the metal syringe, but fortunately it was metal, and there was no problem when it fell to the ground.

From the summary of the experience of the past day, it can be said that the achievements are very large, because 20 students have successfully trained as junior veterinarians, which can ensure the successful completion of future tasks; But it is also full of foreign appearances, and all kinds of strange things have appeared. However, it is obvious that the students have mastered the technical essentials, their self-confidence has been enhanced, and the cooperation between each link has also become more tacit.

The next day went relatively smoothly, and after arriving at the Wujiatun Brigade today, it began to be divided into a group of three people, twenty people plus Stationmaster Li, just 21 people, divided into seven groups, and acted separately, Zhao Weidong also brought a group, Ye Qianru was one of the members. Yesterday, a brigade did not end until 9 o'clock in the evening, and today it will be completed by 12 o'clock, and the lunch will be arranged by the Wujiatun brigade.

In the afternoon, Stationmaster Li took all his classmates to the Liujiatun brigade again, and when he was about to arrive, he suddenly saw that a lot of heading wheat was cut off and thrown on the ground where he was planted, Ye Qianru asked:

"Stationmaster Li, why are so many wheat cut off before it is ripe?"

"This is some time ago to implement the policy of the superiors, each brigade has organized a collection team, door-to-door inspection, the part that exceeds the normal needs is the tail of capitalism, it must be disposed of, it will be confiscated, these wheat belongs to this category, this is to cut the tail of capitalism, and now it is advocating 'I would rather have the grass of socialism than the seedlings of capitalism'."

Ye Qianru only knew that this was the case after hearing this, although she had doubts in her heart, she also knew that she couldn't ask any more, otherwise it would bring trouble to her parents. The classmates next to them listened to it, and they didn't dare to say a word, they finally understood in their hearts why Zhao Weidong asked everyone to promise to keep it confidential before they realized their dream of making a fortune, and the benefits should be reasonable, so as not to cause contradictions, which is really necessary.

To the Liujiatun Brigade, under the leadership of the cadres of the brigade and the cadres of the production team, we continued to divide into seven groups to carry out epidemic prevention work, and vaccinated all pigs against swine fever. The following is carried out in an orderly manner, and the prevention work of a brigade can be completed every half day, and on Saturday, the Linjiatun brigade with the heaviest task will be arranged, because this brigade not only has farmers raising pigs, but also the brigade has run a large pig farm with more than 300 pigs, so this brigade will be arranged on the last day.

On Saturday morning, the students rode for an hour to the Linjiatun Brigade, and discussed whether to go to the brigade pig farm or to the members' homes first.

So, seven epidemic prevention teams, under the leadership of the cadres of the brigade and the production team, went door-to-door to vaccinate the pigs of the members, and at more than 11 o'clock, each team successively completed their respective epidemic prevention tasks, and returned to the brigade, the brigade arranged a simple meal for everyone, but the amount was still enough, and everyone was very full.

After the meal, all the people walked to the pig farm of the brigade, because the distance is not far, it is a few miles, and it takes ten or twenty minutes to walk, and soon they came to the pig farm.

Zhao Weidong walked in and took a look, he was taken aback by this scale, the memory of this in the previous life has been a little light, and now he is alive and again in front of him, such a large-scale farm, and it is thriving, a pig is fat and fat, it is not that this era can not engage in the economy, but the people of this era do not attach importance to economic work, but it is not all right to say that they do not pay attention to it, the country is advocating the economy, but the country's economic quality has nothing to do with every individual person, It may be that one political movement after another has confused people's minds, doing more and doing less, why do I do so much? As a result, labor productivity has been greatly reduced, and many people who work hard do not rely on the promotion of personal interests, but rely on noble sentiments as the driving force, and there must be many more people with high morals in this era than in later generations, otherwise it would not be possible to study the great achievements of two bombs and one star in an era of extremely difficult conditions; But Zhao Weidong believes that most people do not have such noble sentiments, they have to rely on interests to drive, and they are not motivated without interests; And thousands of years of history have proved a truth, the ruler of that dynasty gave the majority of people a happy life, that dynasty became strong, and the ruler of that dynasty gave the majority of people a miserable life, then the future of the dynasty will come. Giving the people a happy life is the foundation for the survival and development of this ruling class, and the people's pursuit of a happy life is legitimate and reasonable,......

With the efforts of 21 people, the more than 300 big fat pigs in the pig farm of the brigade were injected with swine fever prevention vaccines, and the task was completed in only two hours.
