Xiao Ming (A Ming) is a character It is the name of the person who explores the subject in the text exercises and the protagonist of the joke. Because this name is born with the temperament of a cold joke, and was famous for telling cold jokes in school, it has become the name of the protagonist in many jokes, often appearing in texts, titles and jokes. In a joke.

Xiao Ming is a figure who has dominated primary school Chinese, mathematics textbooks, and even political exercises for the majority of people born in the 1970s, 1980s, 1990s, 2000s, and 10s. Hong and Xiaoqiang are collectively known as the "Golden Invincible Iron Triangle".

Xiao Ming, Xiao Gang, and Xiao Hong, these three names that have accompanied generations of people through childhood are still active in various textbooks and application questions. However, due to the revision of mathematics books, most of them have been Replaced by A, B, and C. They are our closest childhood friends. Time flies, and generations of primary school students become middle school students, college students, and then enter the society. These two partners back then have long been forgotten by people. By chance, I heard their story. I sighed for a long time and finally chose to record it. Come down.

Xiao Ming and Xiao Gang are neighbors and were born in the same year. Xiao Ming's father is a government cadre, and his mother is an employee of a state-owned enterprise, and his family is well off; Xiaogang's father is an ordinary worker, and his mother opened a canteen at home after being laid off, making life difficult.

Xiao Ming and Xiao Gang have played together since childhood and entered kindergarten together. They have been in the same class from kindergarten to elementary school. Xiao Ming is well-behaved and sensible, has excellent academic performance, and is the monitor of his class. Xiaogang is lively and active, full of curiosity about everything, but he cannot sit down quietly to do his homework, and his grades are poor. The teacher said: "Xiao Ming is a good student, and Xiao Gang is a poor student. Everyone should learn from Xiao Ming and not mix with Xiao Gang."

Xiao Ming's grades are getting better and better, and he has frequently won Mathematical Olympiad awards. The principal has praised Xiao Ming at morning meetings many times and encouraged everyone to learn from Xiao Ming. Xiaogang's grades got worse and worse and he started fighting, smoking, skipping school and surfing the Internet. The principal repeatedly criticized him by name at the morning meeting and asked everyone to take a lesson from him.

After graduating from elementary school, Xiao Ming entered the city's key middle school, while Xiao Gang entered a lower-class middle school. The most common thing Xiaogang's mother says every day is: "Look at Xiao Ming next door, how promising he is!" Xiao Ming's mother often says: "Don't associate with Xiao Gang next door, this kind of person will lead you down."

After junior high school, Xiao Ming was admitted to a provincial key middle school, and Xiao Gang entered a vocational high school. Xiao Ming's father became more and more successful. They moved out of their old house and moved into a high-end community with excellent conditions. Xiaogang's parents are still working hard and living in poverty. Xiao Ming spent all his time reading books and doing questions, and his grades were always among the best. He knew that he would have a bright future; Xiaogang became obsessed with rock music and sang hoarsely in the wind every day until tears flowed. He felt that his future was uncertain.

One day, when Xiao Ming went home, he saw an old man lying on the roadside. He subconsciously wanted to help but stopped suddenly, pretending not to notice and walked away quickly. Xiaogang happened to be passing by this road, so he ran over and picked up the old man and called a car to the hospital. The old man eventually died after resuscitation failed, and his family members insisted that Xiaogang had hit someone. The court eventually ordered him to pay hundreds of thousands in medical expenses, which made the family even worse. But later it was confirmed that the family not only gave Xiaogang hundreds of thousands, but also apologized and gave him 10,000 because they were from a wealthy family

Xiao Ming was admitted to a prestigious domestic school, listened to lectures by experts every day, and communicated with overseas Exchange and discuss advanced theories with friends. Xiaogang entered an auto repair shop and worked for the masters in the factory. In four years, Xiao Ming caught up with the school belle, served as the president of the student union, and did research projects with well-known domestic professors. People said that this young man had a bright future; Xiao Gang worked in an auto repair shop every day, because he was an apprentice, and all the dirty work was done by Xiao Gang. He came to do it, it was bitter and painful, and he knew whether he was warm or cold.

After graduating from college, Xiao Ming joined a Fortune 500 company.

Soon he fell in love with the daughter of a company boss, and soon they started talking about marriage. They bought a house in the city center and each of them had a car. Xiaogang became a regular employee, and his boss gave him a salary increase. Since the debts from that year had not been paid off, the family was still living in tight conditions, and no girl was willing to come to the house. In the end, Xiaogang, who was nearly thirty years old, married a migrant woman with little education and made do with it.

Later, Xiao Ming began to take the civil service examination and used his father's connections to easily get a good position. I sit around in the office every day, socializing and eating. After his father retired, he was promoted day by day and took over his father's job. His son studied in an aristocratic primary school. He often said to his son: "Son, you have to work hard to be a good person." Xiaogang became a master in the factory. His mother became ill and died in his early years. He took his father over and they became a family of four. His son was studying in an ordinary primary school. He often said to his son: "Son, you must be kind!"

After the reform and opening up, Xiaogang went abroad to start a business. He became a small boss of an auto parts factory, and his business He worked prosperously and made his first pot of gold in a few years. At that time, real estate was just emerging. Xiaogang seized the opportunity and took out the auto parts factory as a mortgage. With the money earned in the past few years, he also entered the real estate industry. In less than ten years, it has become one of the top ten leading real estate companies in the country. When his career was booming, Xiaogang quit and joined the entertainment industry. He became a producer and became the godfather of love songs. He composed many popular pop songs such as "His Heart is Too Confused", "Lonely Shazhou Liang", etc. But he never showed his true face to others, leaving only the legend about Xiaogang.

Xiao Ming hooked up with a woman outside, but his wife found out and made trouble with him every day. The mistress nudged him and his wife to divorce all day long, and Xiao Ming felt that life was very boring; Xiaogang worked in the factory every day, and when he came home at night, he saw the little light coming from the house, and no matter how hard or tired he was, he forgot about it. Finally he felt that life was very happy. Do you believe that one day they finally became rich?

The days passed like this, and Xiao Ming and Xiao Gang’s children gradually grew up. They kept repeating the stories of their parents, which were read in textbooks from generation to generation. There will always be Xiao Ming and Xiao Gang. It started from the same starting point, but took two completely different trajectories. However, I often think of Xiaogang back then. I think of the little Gang who couldn't sit still in class and jumped up and down after class. I think of the little Gang who made trouble in order to attract the teacher's attention. I think of the little Gang who was confused and helpless and sang in the wind. I want to walk up to him and say to him: "Kid, you are awesome!"
