Sun Jiadong's achievements in the aerospace industry are by no means accidental. But several important turning points in his life were all inexplicable coincidences. Especially before his involvement in the aerospace industry, his experiences were full of ups and downs, leaving a lasting impression.
    The Opportunity Chapter of 'Star Moon Legend'
    Sun Jiadong was born in April 1929 in Yingkou City, Liaoning Province. In 1948, he was admitted to the preparatory class at Harbin Institute of Technology to specialize in Russian, and later transferred to the Department of Automotive Engineering. If we follow this trajectory, Sun Jiadong may never deal with aerospace for life. But a miracle still happened.

Sun Jiadong in his youth

On the 15th day of the first month in 1950, the Yuanxiao (Filled round balls made of glutinous rice-flour for Lantern Festival) Festival was a joyous occasion at Harbin Institute of Technology. The reason for happiness is very simple, because it is a school dinner that day, and each student will get a bowl of Braised pork belly. This is the long-awaited meal for all students in the school. Food is of paramount importance to the people, and many students even give up the opportunity to reunite with family and friends. Sun Jiadong had already made a plan in his mind: he would eat meat at 18:30 in the evening, reunite with his sister's house at 19:00, and chat with her sister and brother-in-law.
    At 18:00 in the evening, the school cafeteria was overcrowded. The students knocked on the bowl with chopsticks and gazed at the pot of Braised pork belly happily, waiting for the meal time. Some even began to swallow saliva. Sun Jiadong is also among them. At this moment, the school leaders came to the restaurant and publicly announced a message: students who are interested can register for the Air Force on site and take the train to Beijing in two hours. At that time, students all dreamed of joining the military, and if they could join the Air Force, it would be an honor for their entire family.
Sun Jiadong, as expected, also joined the registration queue. The difference is that when other students went back to the dormitory to tidy up their luggage, he accelerated to eat a few pieces of Braised pork belly, and really did both. I just didn't have time to tell my sister about the decision. 20: At 30, Sun Jiadong put on his military uniform and boarded the train heading to the Fourth Navigation School of the People's Liberation Army. One year later, he obtained the qualification to study abroad in the Soviet Union through his outstanding performance, and after graduation, he won the Stalin Avatar Gold Award with a perfect score.
    Many years later, when Sun Jiadong talked about this matter with his subordinates, he said with emotion: "The world is so mysterious, as if that bowl of Braised pork belly changed my life!"
    Love Chapter of Star Moon Legend
    This girl is good. I need to send the letter as soon as possible! "On the early morning of April 6, 1959, Sun Jiadong got up and ran to the post office.
The day before, the Fifth Research Institute of the Ministry of National Defense decided to organize young people from the institute to visit the Summer Palace. As the car drove past Muxidi, Sun Jiadong suddenly remembered that he had forgotten the task of bringing a camera that everyone had given him; So he got off the car and went to borrow a camera from his comrade Liu Enguang, who had studied in the Soviet Union with him in an air force unit.
    Sun Jiadong knocked on his comrade's door and explained that he wanted to borrow a camera. Liu Enguang's wife poured a cup of tea for Sun Jiadong and then pulled her husband to another room.
How old is your comrade this year
    “30。”
    Do you have a partner
    No. The organization is quite concerned about it
    Liu's wife has a clear idea in her mind. When he handed the camera to Sun Jiadong, he also took a photo. Sun Jiadong looked at the young girl's bright and lively eyes in the photo, and his face turned a little red. Liu's wife said, "She is my classmate from Harbin Medical University, named Wei Suping. If you have any feelings, please write to her." As he was about to leave, the understanding Liu's wife handed him a piece of paper with an address written on it.
    After finishing the game and returning home, the first thing Sun Jiadong did was to carefully examine the photo on the table. It feels so good! "He read more and more, feeling more and more moved, so he picked up his pen and wrote a letter. One night later, this' Cupid's Arrow 'flew towards Harbin.
    Legends quickly become natural. Wei Suping also had a strong impression of Sun Jiadong, who had served as a soldier, studied abroad, and engaged in scientific research. 25 days later, he took advantage of the May Day holiday to board the train to Harbin; The two met and had a very pleasant conversation, with a strong sense of regret for meeting too late; 108 days later, the two walked hand in hand into the hall of marriage.

 Sun Jiadong and Wei Suping in their youth

After marriage, the two respected each other as guests. Wei Suping gave her husband the maximum understanding and support with a woman's unique tenderness and generosity. When she gave birth to her daughter, her husband was not by her side; When Sun Jiadong arrived at the bedside the next day, she didn't blame him at all. Due to the special nature of their work, Wei Suping only found out after 30 years of marriage that her husband was engaged in aerospace work. She had no complaints about this. On November 24, 1994, Wei Suping, who had just come out of the hospital, had a sudden cerebral thrombosis. When relatives and friends prepared to call Sun Jiadong at the Xichang Satellite Launch Center, Wei Suping stopped them. She doesn't want to affect her husband's work because she feels small compared to her country. It is interesting that when Sun Jiadong returned to Beijing to preside over negotiations with the American aviation delegation, he fainted on the ground due to excessive use of his brain. When he woke up and learned that he was in the same hospital as his beloved wife, he strongly demanded to be in the same ward as her. I was too negligent as a husband, I want to compensate in the ward! "The doctor couldn't refuse when he heard these touching words. In the hospital room, Sun Jiadong fetching water and peeling fruits for his wife... The two of them seemed to have returned to their first love moment.
    The legendary life of Sun Jiadong is closely related to satellites and the moon. Behind the legend lies his tireless pursuit of knowledge, his unyielding struggle against fate, his sincere love for his country, and his genuine concern for his wife. Sun Jiadong's contributions to the aerospace industry are just like the congratulatory letter sent to him by Qian Xuesen, the father of China's aerospace industry, on his 80th birthday. "Since the first victory of the first artificial Earth satellite, to the complete success of the lunar exploration project, you have made outstanding contributions to the development of China's aerospace industry for decades. The Republic will not forget them, and the people will not forget them. I am proud of your achievements
