Both Luo Xintong and Luo Sensen’s father’s parents’ hometowns are in Fengquan Village, a rural village more than 100 kilometers away from Haibin City, Qinchuan Province. Most people in Fengquan Village have the surname Luo, so the locals call Fengquan Village Luojia Village.Luo Sensen's father, Luo Zhengwen, became the only college student in the 80s. After graduation, he stayed in Haibin, the provincial capital, and taught in the high school of the High School Affiliated to Normal University in Haibin City. He married Tong Jiazhi, a female champion in the next village, and Tong Jiazhi got a job. Yu Binhai Land and Resources Bureau, the two were the only married couple in the township who freely fell in love, and they gave birth to Luo Sensen a few years later.Luo Xintong's father, Luo Weidong, worked on construction sites all year round. Luo Xintong had very little memory of his father. Luo Xintong passed away unexpectedly when he was very young. He was directly pierced through his head by a steel bar on a construction site... Fan Wenyan Silently finishing Luo Weidong's funeral, in the rural area where "father died and mother remarried" prevailed, suffering did not overwhelm the strong mother. Fan Wenyan, Luo Xintong's mother, brought Luo Xintong, who was five or six years old, and his younger brother Luo Xinheng, who was still babbling. , and the two elderly people are still strong and live well. The grandparents of Fan Wenyan and Luo Xintong are farming at home in the country, and they still gave Luo Xintong and his younger brother a good childhood even though they lost their father. When Luo Xintong was laughed at by his friends as a child without a father, Luo Xintong ran home crying. Luo Xintong's mother would gently stroke his son's head and teach him not to compromise with life.Fan Wenyan raises dozens of pigs and hundreds of chickens every year, and also contracts two acres of fish ponds. She grows the crops into cash crops and sells them in the town market. Live the originally miserable life like a flower.

Luo Xintong's family and Luo Zhengwen's family have a very good relationship. The two families live very close to each other. During the holidays, the three members of the Luo Sensen family will come back from the city to live with Luo Sensen's grandfather at home. The old man is not used to living in the city. Every time I go back to the countryside, the two families will get together, the old people of the two families will have a lively reunion dinner at home, and the adults of the two families will talk about the outside world together, Luo Xintong and There is a two-year age difference between the two of Luo Sensen, and the children had a great time playing together. Every time Luo Sensen went back to the countryside, he would give Luo Xintong some candies, snacks and toys for the children in the city. One day, the children in the same village bullied Luo Sensen, and Luo Xintong stepped forward to protect Luo Sensen.Luo Xintong heard from his parents and grandparents that Luo Sensen's parents were cultural people when he was young. When Luo Xintong grew up, he stopped fighting with his younger siblings. When he was eight or nine years old, he asked his younger sister Luo Sensen to bring him some books. Look, when Luo Xintong listened to Luo Sensen talking about the things in the city, Luo Xintong always listened with bright eyes, and yearned silently in his heart.Every time the Luo Sensen family returned to the city, Luo Xintong would send them to Luo Sensen and his family. Luo Xintong's mother always rubbed her son's hair gently. After Sensen returned to the city, Luo Xintong was always very careful and serious. Flip through the book Sensen brought back, and neatly write down the notes after reading in another notebook.Luo Zhengwen liked this poor and sensible child very much, so Luo Zhengwen recognized Luo Xintong's godson during the Chinese New Year, and held a small-scale ceremony where the eight or nine-year-old child bowed down to his godfather and godmother.

Seeing Luo Xintong grow up day by day, her academic performance has always been the best in her class. Seeing that elementary school is about to finish, and after the new year, she will go to junior high school. There is only one junior high school with poor teaching quality within ten miles of Luojia Village. The high school that Luo Zhengwen studied in those years was nearly [-] kilometers away from home, and the quality of teaching was not good. Luo Xintong's mother, Fan Wenyan, knew that studying was the only way out for her child in the future, so she wondered if she could ask Luo Xintong for help. Luo Sensen's godfather, Luo Zhengwen, Luo Sensen's father, is to see if he can go to the school in Haibin City.

During the Chinese New Year, Luo Sensen's family came back. Luo Xintong's mother Fan Wenyan took Luo Sensen's mother Tong Jiazhi to talk about her thoughts. Luo Sensen's mother liked Luo Xintong since she was a child, and immediately agreed to the matter. Immediately afterwards, Luo Sensen's father was called. Without further ado, Luo Zhengwen called Luo Xintong and asked him if he would go to Binhai Junior High School with him and Sensen. Before the blushing Luo Xintong could speak, Luo Sensen began to say, well, well, well, well, a little girl who was almost 10 years old at this time, when she heard that her little friend was going to the city with her, her eyes lit up, she kept jumping happily, and shouted that her brother would protect her , no longer afraid of being bullied by others.Since then, Luo Xintong has worked harder, fearing that his poor academic performance would embarrass his godfather and mother.

In mid-August, Luo Xintong had just turned 8 years old and left his hometown for the first time. Although it was only more than 12 kilometers away, it seemed to have entered another wonderful world.In order for Luo Xintong to go to school in Haibin City, godfather left a lot of relationships. The household registration system was very strict back then, and the school was arranged, so he worked in the junior high school of the High School Affiliated to Haibin Normal University where godfather worked. His father's house was not far from the High School Attached to Normal University. Luo Xintong's parents originally wanted Luo Xintong to board at the boarding school, but Luo Zhengwen and Tong Jiazhi firmly disagreed, saying that they had a small study in their house and set up a bed. He rides a bicycle or takes two bus stops to go to school every day. Luo Sensen is in the sixth grade in the primary school of the primary school attached to Binhai Normal University. The primary school and the junior high school are very close to each other. He learned to ride a bicycle, and wandered around the community on a bicycle every day. Luo Zhengwen and Tong Jiazhi did not allow them to ride to school because they were too young, so they let him take the bus to and from school every day.Luo Sensen stuck out her tongue to express her dissatisfaction, Tong Jiazhi had no choice but to wait until she entered junior high school next year before riding a bicycle, and the two siblings rode to the junior high school together.Only then did Rosenson give up in satisfaction.

After Luo Xintong went to the High School Attached to Normal University, he did well in school, but he stayed in the countryside all the time since he was a child. The environment was a bit out of place, but fortunately Luo Xintong and Sensen could give him "tutorial" on the way home from school. This eccentric sister told him bit by bit, sometimes Luo Sensen talked endlessly, and when he got home, he still babbled endlessly. Zheng Wen always knocked on Luo Sensen's head, telling her not to spoil her brother, and she was very nervous in junior high school.In order to prevent Luo Sensen from corrupting Luo Xintong, Luo Zhengwen's father enrolled Luo Sensen in addition to the piano class he had studied for four years, and also enrolled her in various other training courses. The same body was a little weak, so he also enrolled Luo Xintong in Taekwondo. On weekends, Luo Zhengwen or Tong Jiazhi took the two children to start various training classes. , the TV at home has completely become a decoration. Occasionally Tong Jiazhi cooks, and the two children will help clumsily. Often the winner is a whole mess, and the angry mother Tong drives out of the kitchen with a shovel.

During the vacation, Luo Xintong and Luo Sensen's family went back to their hometown to visit their mother and grandparents. Luo Xintong's mother would also come to the city to visit Luo Xintong when she was free. Every time she came here, she would bring a bunch of home-grown vegetables and fruits and farm bacon .

Three years passed in a flash, Luo Sensen entered the third year of junior high school, and grew into a slim girl. Luo Xintong's eyebrows were picturesque, his eyes were dark and bright, and he was a lot taller. Some even went straight to 180 trend, and his godfather made him insist on morning jogging and taekwondo practice every day. Although he still looks very thin, he is of the thin type, and his body has become much stronger. He looks full of sunshine and vitality.From Luo Sensen junior high school, Luo Xintong and Luo Sensen rode bicycles to the High School Attached to Normal University. The two of them always met many alumni looking back while riding bicycles. Luo Xintong didn't pay attention to these things, but Sensen always Tell him who is looking at you, who is looking at yourself, Luo Xintong has always turned a blind eye to these, just smiled at his sister: "Ride well, don't look at people, look at the road."

Luo Xintong had just entered high school this year, and his study was even more intense than in junior high school. Luo Zhengwen and Tong Jiazhi surrounded their two children. Finally decided to choose science. At this time, Luo Xintong gradually emerged in the class. Luo Xintong's godfather Luo Zhengwen has always been the physics teacher of Luo Xintong's class. He didn't want to embarrass his godfather and studied hard. He is very talented. He has always been number one in mathematics and physics in his class. He not only became the representative of the physics class in the class, but also served as a study committee member, and soon ushered in the second year of high school.Sensen also entered the high school of the High School Attached to Normal University.In the September school season, the school will organize orientation activities for new students. Luo Xintong's sophomore year of high school will inevitably become the main force of the orientation activities. It was because of the double pressure from the head teacher and the grade director that he finally agreed to host the welcome party.
