Is Qian Xuesen's ballista confidential?
From the available information, Qian Xuesen's ballista trajectory was not completely confidential. The boost-glide trajectory design concept proposed by Qian Xuesen had been publicly discussed. For example, China's TF- 17 conventional missile used this trajectory design, and the United States and Russia also relied on this trajectory to develop products. There were many military science content to analyze its principles and characteristics, such as the parabola trajectory similar to conventional ballistic missiles in the front section, and the relatively straight gliding trajectory in the middle and rear section. These situations indicated that the basic concepts and characteristics of Qian Xuesen's ballista were known to the outside world and were not completely confidential.

What is Qian Xuesen's 749 game?
It was said that Division 749 was an organization founded by Qian Xuesen. On April 1, 1968, Institute 507 (the Institute of Cosmic Medicine and Engineering, later renamed the Beijing Aerospace Medical Engineering Research Institute, the predecessor of the China Astronaut Center) was established. It had a subordinate department for supernatural phenomenon research. This was the so-called Bureau 749, which was born in the 1970s (it was established in September 1974, hence the name Bureau 749). The 749th Bureau was considered to be specialized in researching supernatural phenomena and human special abilities. Its confidentiality level was once the top secret of the country. It claimed to be in charge of aerospace intelligence research, but in fact, its research field involved the exploration of supernatural phenomena. However, the accuracy of its role in supernatural phenomenon research had not been fully confirmed by the government. Watching "749 Match" wasn't enough. Everyone, please click to read the novel!

Spirit Realm Qian Xuesen
30 years ago, Qian Xuesen translated virtual reality technology as " spirit realm." He believed that the emergence and development of Spirit Realm technology would expand the perception of the human brain and the experience of human-computer integration, allowing the integration of humans and computers to enter an era of deep integration. Qian Xuesen was one of the founders of China's aerospace industry. He had deep thoughts on the standardized work of scientific and technological terms. He was well-versed in both Chinese and Western cultures, so he not only required the naming of Chinese terms to accurately express the concept of the original text, but also to express the "Chinese flavor." Qian Xuesen's academic thoughts and contributions to science and technology were reflected in his letters and works. Although Qian Xuesen predicted the potential of virtual reality technology 30 years ago and named it " Spirit Realm," he was already over 80 years old at that time. Therefore, there were fewer technical details in his letters. Instead, he proposed more as a strategist and strategist to guide the future direction of Chinese science.
Qian Xuesen, 749 departments, 507 movies
Director Lu Chuan mentioned in his "Nine-story Demon Tower" creation notes that he had joined the mysterious military unit, Bureau 749. Bureau 749 collected space intelligence and analyzed supernatural events, while Institute 507 was an institution that mainly studied "human science"(including special abilities, etc.). It was established by Qian Xuesen and belonged to the Fifth Research Institute of the China People's Liberation Army. At present, there was no movie with the theme of "Qian Xuesen, Bureau 749, Institute 507", but the movie "Nine-story Demon Tower" had a certain connection with Bureau 749.

Qian Xuesen's struggle story is short
Qian Xuesen was born in 1911. After studying in the United States, he studied in the fields of aeromechanics, solid mechanics, rockets, missiles, and so on. At the age of 28, he became a world-renowned aeromechanicist. In 1949, when New China was founded, he decided to return to China to work. He was detained because of his confidential work and was still not free after bail. In 1955, he sent a letter asking for help and returned to China in October of that year. After returning to China, he quickly put himself into work. In 1956, he drafted a proposal to establish China's national defense aviation industry and was approved, taking on the heavy responsibility of manufacturing missiles. At that time, most of the team members were fresh graduates. He compiled the Introduction to Missiles and enlightened the first generation of missile and rocket developers. In 1960, the imitation of the Dongfeng-1 short-range missile was successfully launched. In 1962, the first test of the Dongfeng-2 failed. While he cheered up the researchers, he also bore the pressure himself. After the Gobi Desert field investigation, he obtained a fault report, which made the Dongfeng-2 launch successfully again two years later. In 1980, the Dongfeng-5 intercontinental missile was successfully launched. In 1991, he was awarded the title of National Outstanding Contribution Scientist. In his later years, he still paid attention to the development of manned space technology. His years of persistence laid the foundation for China's aerospace development, and he also led research and cultivated talents in the field of mechanics. The story of one person and a group of people is equally exciting. Everyone is welcome to click and read it!

Qian Xuesen's Ancestor's Iron Certificate
Qian Xuesen's ancestor's cinnabar book was made in the fourth year of Emperor Zhaozong's reign (897 AD), 1115 years ago. Qian Qian was given a "Red Book Iron Certificate" by Emperor Zhaozong of Tang Dynasty for his meritorious service. There were 333 words on it, which clearly stated that Qian Qian could be forgiven nine deaths and his descendants could be exempted from three deaths. The "Red Book Iron Coupon" was a gold medal that the ancient emperors gave to meritorious officials to avoid death. This piece was the earliest known "Red Book Iron Coupon". Because of its owner's identity, it was also called "Qian Qian Iron Coupon" or "Qian Wang Iron Coupon." After the fall of the Tang Dynasty, the dynasty changed, but Qian and his descendants still regarded it as a treasure. In the Ming Dynasty, a corrupt official appeared among the descendants of the Qian family. His son took out a 500-year-old death-exemption iron coupon. Zhu Yuanzhang considered the outstanding achievements of the Qian family's ancestors and the talents of the future generations. He could not bear to see the Qian family's bloodline end, so he recognized the iron coupon and let the corrupt official go. The Qian family strictly abided by the family precepts. After escaping death, the later generations abided by the family precepts even more. They studied hard and produced many famous people with lofty ideals. Qian Xuesen was the 33rd grandson of Qian Keng. Watching "749 Match" wasn't enough. Everyone, please click to read the novel!
