Qian Xuesen’s main patriotic deeds

In 1947, the 36-year-old Chinese scientist Qian Xuesen was hired as a tenured professor at the Massachusetts Institute of Technology. This is a high honor, which indicates Qian Xuesen's generous treatment and great future.

Why does the United States value Qian Xuesen so highly? Because he is an outstanding student of von Kármán, the top expert in aeronautical science in the United States, and one of the five members of the earliest rocket research organization in the United States, the Caltech Rocket Research Group.

Under the guidance of von Karman, rocket research made significant progress and contributed to the victory of the anti-fascist war. In those difficult days, Qian Xuesen showed his outstanding talents. An aviation science formula that occupies an important position in the history of aviation science: the famous "Karmen-Money Formula" was born. This is a formula proposed by von Karman and produced by Qian Xuesen. It is still widely used in aviation technology research.

However, when Qian Xuesen learned the news of the founding of the People's Republic of China, this scientist who missed his motherland every moment was immediately immersed in great joy. Qian Xuesen has lived in the United States for more than 10 years and is known as "the first rocket expert in a leading position in the United States." He has money, status, and reputation. But he thought: I am Chinese and my roots are in China. I can give up everything in the United States, but I can't give up my motherland. I should return to the motherland as soon as possible and contribute all my strength to the construction of New China! He also said to Chinese students studying abroad: "The motherland has been liberated, and the country is in urgent need of construction talents. We must quickly apply the knowledge we have learned to the construction of the motherland."

Qian Xuesen's decision to return to China caused a stir Panic among relevant parties in the United States. They believe that if Qian Xuesen's expertise is brought back, China's science and technology will advance at a high speed. A leader of the U.S. Navy once said to the U.S. official responsible for leaving the country: "I would rather shoot Qian Xuesen than let him leave the United States!" "Qian Xuesen is worth at least five divisions of troops."

Qian Xuesen’s plan to return to China was severely hindered. Official U.S. “documents” informed him that he was not allowed to leave the United States. Originally, his luggage had been loaded on a barge and was ready to be transported back to the motherland by water. However, the U.S. Customs insisted that the books and notebooks he planned to take home contained important secrets, and falsely accused Qian Xuesen of being a "spy." In fact, some of these books and notebooks are public textbooks, and the rest are Qian Xuesen's own academic research records.

One wave has not subsided, but another wave has arisen. A few days later, Qian Xuesen was suddenly arrested and imprisoned in an island detention center, where he was subjected to endless torture. The guards came into the room every 10 minutes and turned on the lights every night, making it impossible for him to sleep. Qian Xuesen's experience aroused the sympathy of his colleagues and students who insisted on justice at Caltech. After strong protests from them and other upright people, the US secret service was forced to release him. But the persecution of Qian Xuesen did not stop. They restricted his movements, monitored and checked his letters, phone calls, etc. Despite various restrictions, Qian Xuesen did not give in. He kept making strict demands: resolutely leave the United States and go back to China!

In the days when he was striving to return to China, Qian Xuesen was more concerned about the construction of the motherland. He often learned about the situation of New China from newspapers such as "Overseas Chinese Daily" and discussed issues related to the construction of the motherland with Chinese scientists and overseas students. In order to be able to return home quickly, he only signed a short-term contract when renting a house. I have prepared three small, lightweight boxes at home, ready to fly back to China at any time.

Five years have passed. Qian Xuesen's struggle to return to China has received support from people who uphold justice around the world, and has also received great concern from the Chinese government. Premier Zhou Enlai personally understood his situation and instructed Chinese representatives participating in ambassadorial talks between China and the United States to raise the issue of Dr. Qian Xuesen's return to the country.

In August 1955, this diplomatic struggle finally won, and the US government was forced to agree to Qian Xuesen's return to China.

On the early morning of the second day after arriving in Beijing, Qian Xuesen, his wife and their two children came to Tiananmen Square. He said excitedly: "I believe I will be able to return to the motherland. Now, I am finally back!"

Qian Xuesen overcame many obstacles and returned to China, immersing himself in the research of military science. He devoted himself to what he learned, paid close attention to foreign scientific trends, constantly launched new scientific research results, devoted his best efforts to the national defense of the motherland, and made great contributions. He was known as the "Father of Missiles" and was awarded the title of "Father of Missiles" by the State Council. The honorable title of "National Model Worker".

It is the dream of many people to settle down in the United States and be hired as a tenured professor. But Qian Xuesen gave up all this for the sake of the prosperity of the motherland. Today, when the economic tide is impacting society like a scourge, Qian Xuesen's patriotic words and deeds undoubtedly embody the soul of the Chinese nation and show the power of patriotism to inspire people with lofty ideals and benevolence.
