Detained
In 1949, when the news of the birth of the People's Republic of China reached the United States in the middle-aged Qian Xuesen, Qian Xuesen and his wife Jiang Ying discussed rushing back to the motherland at an early date to serve their own country. At this time, the United States, led by McCarthy, carried out a comprehensive investigation of the Communists, and set off a frenzy throughout the United States that drove employees to allegiance to the United States government.
Suspected of being a communist and refusing to expose his friends, Qian Xuesen was abruptly revoked by the U.S. military department for his certificate of participation in classified research. Qian Xuesen was very angry and used this as a reason to ask for a return to China. In 1950, when Qian Xuesen went to the port to prepare to return to China, he was stopped by American officials and put him in prison, and the us Navy Deputy Secretary danny Jimble said: "Wherever Qian Xuesen goes, he is worth the strength of 5 divisions."
Since then, Qian Xuesen has been persecuted by the US government, and at the same time, he has lost his precious freedom, and he has lost about thirty pounds in a month. Immigration raided his home and detained him on Themina Island for 14 days until he was released after receiving a hefty $15,000 bail from caltech.
Later, customs confiscated his luggage, including 800 kilograms of books and notebooks. It took U.S. prosecutors to review all of his materials again before proving his innocence.
