What did the United States do to prevent Qian Xuesen from returning to China in the movie Qian Xuesen?

1949 10 10/day, People's Republic of China (PRC) was founded. On the other side of the ocean, Qian Xuesen heard the news and decided to return home with what he had learned all his life. After consulting with his wife Jiang Ying, they decided to finish their work and leave for home. Before leaving, they packed all their luggage and said goodbye to their good friends one by one. 1950 On August 23rd, Qian Xuesen walked into a building in Washington. He came here to bid farewell to danieldae kim Belle, then Deputy Secretary of the United States Department of the Navy.

However, I didn't think of this difference. Life and death extended Qian Xuesen's return time by five years. What the hell happened?

At that time, Qian Xuesen not only served as a consultant to the US Naval Ordnance Research Institute, but also served as an important member of the US Department of Defense's scientific advisory group. In the view of the US Deputy Secretary of the Navy, one Qian Xuesen can be worth five divisions, and it is undoubtedly a great loss for the United States to let him return to China. Moreover, a large number of military secrets held by Qian Xuesen are also a big threat to the United States. He immediately called the US Department of Justice, hoping that the government would intervene to prevent Qian Xuesen from returning to China.

After learning the news, the US government took immediate action. First, Qian Xuesen's luggage to be checked back to China was detained, claiming that it contained confidential documents. What is even more infuriating is that the next day, at the instigation of the relevant departments, all major news media in the United States published this news on the front page, and some reports even directly slandered Qian Xuesen as a "spy." The Immigration Bureau of the US Department of Justice made a formal decision to prohibit Qian Xuesen from leaving the United States.

At the same time,1September 7, 950, two agents wearing immigration documents knocked on the door of Qian Xuesen's house and took Qian Xuesen, who was regarded as a "recidivist", to Temiro Island Prison. In this dark prison, the guards watched him for 24 hours, did not allow him to talk to anyone, and tried their best to torture him. In this dark room where Qian Xuesen is being held, the prison guards turn on the light every fifteen minutes or shine a flashlight directly on his face, making him unable to rest.
