One day, Shiyuan Group issued a “ death list. Yu Hui (played by Wang Zhide) and five other employees, HR Zhang (played by Chen Zifeng), Ajiu (played by Tang Haoran), Zhenzhen (played by Yang Yawen), Even (played by Luo Yunzhi) and Ango (played by Mai Peidong) need to undergo a semester retraining plan, and those who fail to meet the standards will be fired immediately.The place where the retraining was actually an absolute primary school - Qinshi Primary School!Six over-age primary school students plus six ” true little four students Bozi (Huang Ziyao), Meiyou (Fang Xin), Xiaoyu (Su Tianle), big sister (Luo Qiannuo), Xu Yue (He Yangang) and Elly (Li Zixin) formed the %4S class, with the young, beautiful but serious Miss Yi (Lin Xuanyu) serving as the head teacher.Bozi often takes the initiative to get close to Yuhui and takes good care of him, but Yuhui doesn't like to be with elementary school students, and even doesn't want to be seen wearing school uniforms.He was concerned about the company but found that the newly hired temporarily took his position easily, which was hit hard.

In order to speed up the understanding of the adults and children in Class 4S, Miss Yi asked the whole class to be divided into three groups, each with two adults and two children, and the classroom evaluation was conducted using group briefings and common sense Q&A competitions.I thought that the level of elementary school was not difficult to deal with, but now primary school students are busy with extracurricular activities, and the gap in their background and personality has taken a long time to get started.Miss Yi hopes that the students can select the chief and deputy squad leader by one person and one vote.In order to consolidate the reputation of his own group, HR Zhang wins his classmates everywhere to vote for Xu Yue in the same group. Xu Yue's main opponent is Miyou, who is elected as the class monitor every year.On the eve of the Common Sense Q&A competition, HR Zhang discovered that Xu Yue had dyslexia, which was a bolt from the blue!He warned Xu Yue not to reveal his weaknesses, but was accidentally discovered by Meiyou.

Qinshi Primary School Celebration Open Day is coming soon, and it is rumored that Ye Yihe (played by Gao Hanwen), the owner of Shiyuan Group, will attend.Yuhui, who admires Ye Yihe and HR Zhang, who strives for the best in the workplace, decided to join forces to lead the 4S class to compete for the % most popular classroom award, hoping to accept the award in Ye Yihe and make a big splash.However, Yu Hui and HR Zhang cooperated on the surface, but secretly they were full of calculations, and even moved office politics to the classroom, which made people at a loss.Even clearly understood the problem, but because of lack of self-confidence, he put away his opinions, which made the 4S's problem grow bigger and bigger like a snowball.Due to communication errors, the exhibition device was destroyed due to a short circuit. Seeing that everyone was shirking responsibility, Even took out his life's courage to stop everyone and lead everyone to renovate the classroom.

Ajiu and Zhenzhen’s fate started by participating in the Shiyuan Group’s new camp. They quickly developed into couples, but this underground relationship ended with breaking up, and goodbye is no longer friends.But the enemy met again in elementary school, and the old resentment had not yet disappeared, and the new revenge was born again. During the STEM class, Ajiu accidentally injured Zhenzhen, and Zhenzhen immediately concluded that Ajiu was willing to take revenge!When the 4S class saw that the two were in trouble, they had to split into two groups to comfort each other, but found that the two had a deep misunderstanding. In fact, they still cared about each other very much, so they took the opportunity to trap the two in the computer room, thinking that they could create communication opportunities.Unexpectedly, the two of them kept turning over old accounts, and Zhenzhen couldn't help but chase Ajiu. Fortunately, the students rescued the situation in time.

Every year, Qinshi Primary School holds “1-minute genius performances, and this year, the 4S class will be the first to kick off.Cai Xiaoqi (played by Ai Wei) emphasized that there is no limit on performance, and the most important thing is to enjoy the process.In order to prove that his strength is no worse than that of young people, HR Zhang decided to challenge the extremely difficult Seshifeng.Meanwhile, Stephanie, a daughter who is in high school, hopes to attend the school stargazing camp, but HR Zhang refused on the grounds that the event had nothing to do with her studies, disappointing Stephanie.”One-minute genius performance %The day finally came. HR saw that the students were full of enthusiasm for the performance, but he did not enjoy it at all, and he was in a low mood due to excessive tension.When he saw a rubber rope on the playground, he suddenly had a whim and asked for another performance.

One night, Yuehui and her old colleague Gary were having a drink in the bar.The next day, Yuhui was late due to a hangover and was drunk. Miss Yi asked to see her parents. Unexpectedly, Yuhui's mother turned against her and seemed to be intentional about matching Miss Yi and her son, which made Miss Yi unable to withstand for the time being.Yuhui saw her mother away, but she found that her mother had brought her suitcase and was preparing to go to her home for one week.Yuhui could not refuse, but he, who was used to living alone, became a little scared when facing his mother's excessive care and stayed alone until dinner time every day.The mother realized her son's discomfort and decided to end “staycation” early.

“The different sports meetings are approaching, and the attitude of the 4S class is still scattered.As the captain, Xiaoyu hopes to lead his classmates to win the competition, but he lacks leadership skills and often relies on the help of his athletes and great sisters.Another captain, Ango, is a ” susceptible man who is % susceptible to injury. He is full of fear of the game and often uses excuses to avoid practice.Xiaoyu and his sister disagree on the practice arrangement and fought each other.As a result, my sister was injured during practice because of her competitive nature.Xiaoyu and the elder sister each started crying guiltily, but unexpectedly, Brother An also cried, saying that his zodiac signs were in conflict with the ox and the sheep, which would drag everyone down.It turns out that Brother An had implicated his favorite female colleague Zhuzhu and was injured. Zhuzhu is a sheep.

Because of winning in “ of the ” different sports meets, 4S class won a “ Scotland ” trip as a reward!However, “Scotland” was originally located in Shatou Kok Scottish Farm%.Under the scorching sun, Class 4S carried out one activity after another under the arrangement of Miss Yi, which was extremely painful and more difficult than class.Yu Hui took the lead in hiding, and even said that when he was a child, he had seen fireflies on nearby mountains. Everyone else wanted to see the secret realm of fireflies, so he decided to secretly go up the mountain to see fireflies without telling it.In the evening, Class 4S went up the mountain to search, but there were no fireflies. However, because of the children's persistence, everyone finally found the location of the fireflies.

The principal proposed that those who get full marks in common sense tests can deduct one disadvantage. Yuhui hopes to wash the bottom and review it hard, but it is still two points away. I can't help but talk to Miss Yi on the answer, but in the end I was still in vain.After school, Yuhui accidentally discovered that Miss Yi and Miyu's father Terrance were dating privately, and Terrance had divorced in his early years, which made Yuhui enthused about the relationship between the two!After inquiring, Miss Yigang graduated from Terrance for internship, and Terrance was her boss.Later, Miss Yi pointed out her boss’s mistake in public at the Shiyuan Research Press Conference, which was called scheming, and finally resigned.Yuhui learned of the incident and asked Miss Yi to make up for the score in his test, otherwise her dark history would be distributed through the Qinshi Primary School Secret page.Unexpectedly, Miss Yi cried out in grievance after scolding Yu Hui.

Yuhui discovered that Terrance had been very close to a woman named Christina recently, and this person had an unusual relationship with Roger and Peter, the R&D department of Shiyuan Group.It turns out that Terrance is developing a new generation of environmentally friendly materials. Similar materials Shiyuan Group has been researching for many years and wants to register a patent first. Unfortunately, it is technically encountered a bottleneck. Yuhui suspected that Christina was a commercial spy deliberately placed by Roger and Peter around Terrance.As an employee, Yuhui believed that the boss Ye Yihe had the right to know the evil deeds of his subordinates, so he asked everyone to help create a chance to meet.Unexpectedly, Ye Yihe was completely aware of the incident, and even more so that % did not care about the process, but only cared about the result, which disappointed Yuhui.When Yu Hui was at a loss, she unexpectedly learned that Terrance had signed a contract with a new investor, so she hurried to stop it.

The business spy incident between Roger and Peter was exposed, and Ye Yihe was angry and ordered the two to go to Qinshi Primary School for further training. The first task was to report Yu Hui's every move!Roger and Peter became trainees in class 4S. Because they were good at winning people's hearts, they quickly got along with others. Even Bozi, who was inseparable from Yuhui, became obviously distant.Afterglow felt that he was abandoned by his playmates, and he felt bad.On the other hand, Ye Yihe's son Ye Chenglin, due to disagreements with his father, started his own business not long ago and planned to invest in Terrance's new project, but Ye Yihe repeatedly pursued Ye Chenglin's company, which made Ye Chenglin's company in financial difficulties.Ye Chenglin looked for Cai Xiaoqi to help, hoping that he would persuade his father as a friend, but unexpectedly touched Ye Yihe's nerves. He felt that his son and his friend should be in harmony with each other and conspired to betray him!

Bozi, who has always been interested in machinery, teamed up with Yuhui and Xiaoyu to participate in the %high truck design competition.Bozi's lap speed was slower than Xiaoyu, and he still wanted to drive the high truck he designed himself to play in the game, but Yuhui was unable to support his friends, which made Bozi angry.In order to coax Bozi, Yuhui specially queued up for Bozi to buy a limited edition raw toast. Unexpectedly, Bozi was busy modifying high trucks with Roger and Peter, ignoring Yuhui, and even saying that Yuhui was just going through everything, which made Yuhui even more disappointed.The night before the competition, Bozi was still working hard to improve the design. Yuhui went to help to solve the lap problem for Bozi, and the two rehabilitated the old one.However, on the day of the competition, the high truck was deliberately destroyed.

After Yu Hui was dropped out of school, she was officially fired by the group and lost her direction.In order to encourage Yuhui, Miss Yi gave him a heart card on behalf of Class 4S and invited Yuhui to return to school to attend the Christmas party.On the other hand, Ye Chenglin was very angry when he learned that his father planned to maliciously acquire his company and had a big quarrel with his father.On the day of the party, Yuhui finally appeared and celebrated Christmas with Class 4S, but the school suddenly heard news that Qinshi Primary School would be closed for the next school year.It turned out that according to Ye Yihe and Cai Xiaoqi's previous bet, Yuhui had to return the school and then transfer the camp because he failed to successfully complete the % retraining pilot plan.Everyone decided to talk to Ye Yihe, and Ye Yihe offered a bet condition that if Class 4S can win the STEAM competition in the academic community, they can keep the school; on the contrary, employees of Class 4S will be fired by the group.Everyone decided to give it a try, but they had no idea...

Ye Yihe was in a coma in the hospital, and Cai Xiaoqi was with him, but Ye Chenglin was unwilling to stay for a long time, for fear that his father would start another dispute when he woke up.Yuhui felt that it was the trigger point of things and hoped to do more for the school. Cai Xiaoqi pointed out that Ye Yihe was the person who needed help the most, and suggested that Yuhui know Ye Chenglin.It turned out that after Ye Yihe lost his wife in his early years, his temperament changed drastically and began to close himself. He was actually very lonely inside.Ye Yihe finally woke up, Yuhui discussed with everyone in the 4S class and decided to design a board game called “Shiyuan Life ” for the father and son...

Miss Yi asked Cai Xiaoqi why she chose him and the other six people to join the 4S class. Cai Xiaoqi pointed out that in addition to fate, she also saw valuable qualities in each person.Cai Xiaoqi even recalled that he served as the judge of the 30th anniversary plan recruitment competition of % Shiyuan Group. He had read Yuhui's plan and felt that the other party was an ideal and ambitious person.On the day of the graduation ceremony, all members of Class 4S attended. Under the witness of Miss Yi, Cai Xiaoqi, Ye Yihe and Ye Chenglin, everyone received the graduation certificate and shared their feelings on stage. The scene was warm.Everyone was deeply moved when they watched each other's transformation and growth.This strange primary school journey came to an end with laughter and tears.(The finale)
