Why did the United States know that Qian Xuesen's return to China was a great loss to them and finally agreed to release him?

Qian Xuesen returned to China after five years of house arrest in the United States.

The whole story of returning home "I would rather shoot him than let him return home" 1949. When the news of the founding of New China reached the United States, Qian Xuesen and his wife Jiang Ying could not restrain their inner joy and discussed returning home as soon as possible. At that time, there was a hysterical fanaticism in the United States, which drove employees to be loyal to the American government. Qian Xuesen refused to expose his friends because he was suspected to be a producer of * * *, and was suddenly revoked by the US military department. Qian Xuesen was very angry. He said: "I would rather go back to my hometown in China than stay in the United States to be suspected!" What he never expected was that his long-cherished wish to return to China turned into a disaster.

After hearing the news that Qian Xuesen was going back to China, the US Deputy Navy Secretary said, "He knows all the core secrets of the US missile program. One Qian Xuesen is worth five marines. I'd rather shoot this guy than let him go back to Red China! " After that, the Immigration Bureau copied Qian Xuesen's home and locked him in Temina Island.

Tamina Island is an insignificant island in the Pacific Ocean. Very desolate. In the middle of the island is a grim prison set up by an oil exploration well, and there are huge waves outside. The room was damp and dark, and Qian Xuesen was held here. Most prisoners in the same prison are Mexican border criminals. These prisoners speak Spanish, which Qian Xuesen can't understand. In the first few days of detention, he was not allowed to meet Ren Keren or contact with the outside world. During the day, he was interrogated endlessly; At night, every ten minutes, the prison guard turns on the light of the cell, stimulates his eyes with strong light and forbids him to sleep. He was not released until California Institute of Technology sent $654.38 +0.5 million bail. Qian Xuesen was detained for 15 days and lost weight 15 kg.

However, the US Customs set up many obstacles to prevent Qian Xuesen from returning to China. They confiscated the luggage of Qian Xuesen and his wife, including 800 kilograms of books accumulated by Qian Xuesen for many years and notebooks for recording precious materials. In this way, Qian Xuesen was under house arrest in the United States for five years.

Zhou Enlai skillfully used diplomatic means to help him return to China.

1954 In April, the United States, Britain, France, China and the Soviet Union held an international conference in Geneva. Zhou Enlai, head of the China delegation, instructed us to contact Qian Xuesen, a scientist studying in the United States in China, and other detained issues first in the negotiations. However, China's just request was unreasonably rejected by the United States.

On July 25th, 1955, the Ministry of Foreign Affairs of China set up a steering group for Sino-US talks, which was directly led by Zhou Enlai. In August 1955, 1, Sino-US talks were upgraded to ambassadorial level. Despite more than ten contacts between China and the United States, US Congressman Johnson refused to let Qian Xuesen return to China on the grounds that China could not find the real reason for his request.

Just as Premier Zhou Enlai was anxious about this, Chen Shutong, then vice chairman of the National People's Congress Standing Committee (NPCSC), received a letter from the other side of the ocean. The signature in the letter was actually "Qian Xuesen". In order to get rid of the spy's surveillance, Qian Xuesen wrote this letter on a small piece of cigarette paper, put it in a letter sent to relatives in Belgium and gave it to Chen Shutong. In the letter, Qian Xuesen asked the motherland to help him return to China.

Chen Shutong personally handed the letter to Zhou Enlai. Zhou Enlai was overjoyed, and the Ministry of Foreign Affairs quickly forwarded this letter to Wang Bingnan, who was negotiating in Geneva. When Johnson goes back to the old tune-"There is no evidence that Qian Xuesen will return to China, and the US government cannot force orders". Wang Bingnan flashed Qian Xuesen's letter and confidently refuted Johnson: "Since the US government publicly issued an announcement as early as April 1955, allowing scholars studying in the United States to travel freely, why did Dr. Qian Xuesen, a scientist from China, write to the China government for help in June? Obviously, the request of China scholars to return to China is still blocked. " In the face of facts, Johnson was speechless. The American government had to approve Qian Xuesen's request to return to China.

1In August 1955, the US Immigration Bureau issued an exile order to Qian Xuesen, and Qian Xuesen, who had stayed in the United States for five years, finally received a notice from the Immigration Bureau. 1955 September 17, Qian Xuesen boarded the "President of Cleveland" with his wife Jiang Ying and a pair of young children and embarked on a journey back home.

For Qian Xuesen's departure, his mentor and scientist von Carmen said with emotion: "The United States dedicated Qian Xuesen, the greatest genius and the best rocket expert in the field of rocket technology, to Red China!" When he left, the tutor said affectionately to Qian Xuesen, "You have surpassed me academically now. Go back to your motherland and work. Science has no boundaries. "
