In 1990, an ordinary family in Hunan Province gave birth to an extraordinary child, he was Zhang Xiaoyong. Since childhood, Zhang Xiaoyong has shown intelligence and learning ability beyond his peers, especially in science, and has always been at the top of his grades in mathematics and physics. Whenever the teacher has a problem, Zhang Xiaoyong is always the first to answer it correctly. 
Zhang Xiaoyong has a dream to study in the top universities in China. To this end, he never relaxes his exploration and study of knowledge. Even if the teacher wanted to escort him to school, Zhang Xiaoyong resolutely relied on his own strength. He studied day after day, corrected his mistakes, and finally got his wish in the college entrance examination. In 1991, Zhang Xiaoyong entered Tsinghua University, which he had been dreaming of for a long time, with the glorious results of the province's top science student. For him, this is the moment when the seeds of hard work are rewarded. During his studies at Tsinghua University, Zhang Xiaoyong met many of his most prominent classmates. At first, he also had low self-esteem and felt that he had a big gap with them. 
But Zhang Xiaoyong was not discouraged for long. After adjusting his mentality, he used his usual hard work to catch up with them. In many competitions, Zhang Xiaoyong continued to overcome himself, and finally won many awards in mathematics and physics. The students also found motivation in Zhang Xiaoyong's learning attitude. Zhang's teachers recognized his extraordinary talent in science and often praised him as a natural physics prodigy. Zhang Xiaoyong is also keen on physics experiments, and has designed experiments to verify quantum theories, and has achieved fruitful results. With his brilliant mind and unremitting perseverance, Zhang Xiaoyong honed a strong foundation in science at Tsinghua University and became a talented science genius. His story became a model for those who came after him. 
In 1996, Zhang Xiaoyong successfully graduated from Tsinghua University, and his golden dream was about to start. He is full of ideals and wants to display his talents in the field of scientific research and make contributions to the physics community. But the reality is cruel, Zhang Xiaoyong has repeatedly hit a wall in his job search, and the door of the scientific research unit is always closed to him. At that time, competition for jobs during a period of social transition was extremely fierce. Zhang Xiaoyong's family background and connections are obviously insufficient compared with others. In the face of many obstacles in reality, Zhang Xiaoyong's scientific research dream is gradually drifting away. He desperately needs a job to make ends meet. 
Forced to make a living, Zhang Xiaoyong had to put down his ideals and enter an insurance company to engage in insurance sales. This is a heavy blow to Zhang Xiaoyong. He had to deal with the tedious work of going out to visit clients and repeating similar problems. Zhang Xiaoyong's excellent ability did not play well in this sales job. At first, he was always absent-minded and ranked last in terms of performance. But Zhang Xiaoyong was not discouraged, but took the initiative to learn from the experience of his predecessors and strive to build a good relationship with customers. In this unsatisfactory job, Zhang Xiaoyong honed patience and resilience. He worked tirelessly and finally grew into the backbone of the business five years later, taking on the role of department manager. Despite his apparent success, Zhang Xiaoyong is still full of yearning for his ideal scientific career. 
Until one day, a chance chance changed Zhang Xiaoyong's fate. An old classmate introduced him and gave him the opportunity to enter the ideal scientific research position. Zhang Xiaoyong once again showed exceptional talent and soon shined in his new job. The clock hand came to 2007, and Zhang Xiaoyong, who was 47 years old, ushered in another turning point in his life. Unlike most people's regular schedules, Zhang Xiaoyong chose to start a family in his hometown at this age. He married the woman he loved and lived a belated newlywed life. Zhang Xiaoyong's life after marriage seems to be ordinary, but he is very grateful for the quiet satisfaction of his hometown. However, the good times did not last long, and when Zhang Xiaoyong was newly married for a year, his father suddenly fell seriously ill and was dying. 
This sudden change caught Zhang Xiaoyong off guard. Zhang Xiaoyong knows that his father expects him to start a family and have children, but now he has a more important responsibility - to take care of the heroes in life. So, he resolutely decided to quit his job and return to his hometown to take care of his father. In order to earn money to pay for his father's high medical bills, Zhang Xiaoyong began to look for jobs everywhere, from sales to security guards, but none of them were satisfactory for him. Until one day, Zhang Xiaoyong saw a security recruitment revelation and needed to sign a long-term contract. It's a job that takes care of my father and brings life back to normal. Despite his meager income, for Zhang Xiaoyong, a return to a simple family life is what he really desires. 
After successfully passing the interview, Zhang Xiaoyong started working as a security guard. Daily patrols are a new experience for him. This job not only accompanies his family, but also calms his heart down immediately. The family needs him, and Zhang Xiaoyong chooses to take responsibility and live the life he wants. In the blink of an eye, Zhang Xiaoyong has been working in this seemingly ordinary security position for more than 10 years. For others, it may have been a long and tedious experience, but for Zhang, the past 10 years have been the most satisfying time of his life. Every morning, Zhang Xiaoyong came to work on time, dressed in ** to inspect the market and deal with disputes. It's become an innate rhythm in his life. 
At noon, he would have a light lunch in the booth and continue to work quietly. This kind of repetitive work may be too tedious for many people, but Zhang Xiaoyong feels a long-lost peace and contentment. It gave him time to spend with his family and also took him away from the hectic life he used to have. Zhang Xiaoyong will hum some old songs softly after work, with a happy smile on his face. Many people can't understand why Zhang Xiaoyong gave up a good development opportunity to come here, but Zhang Xiaoyong doesn't care. Because of this seemingly ordinary work, it gave him unprecedented peace and happiness in his life.
