On his way home, Qian Xuesen received a telegram from his father: Never get off the boat. Father: I didn't send it.

As we all know, the famous scientist Qian Xuesen has many titles in his life. He is not only the winner of two bombs and one satellite meritorious medal, but also the founder of China manned space flight. Besides, Qian Xuesen is also known as the father of Chinese missiles.

Qian Xuesen was born in Shanghai on 19 1 1. He is the 33rd grandson of King Qian Liu of wuyue. As a famous family in the south of the Yangtze River, Qianjia family has a very prosperous style of writing, and outstanding talents in many fields have emerged in the family. Growing up in such a family, Qian Xuesen is very familiar with China's traditional culture and modern western science.

1934, Qian Xuesen won the boxer indemnity Scholarship and began to study in the United States. However, after going to America, his return journey was not so smooth. During his further study at MIT, Qian Xuesen attracted the attention of the famous professor von Carmen.

He personally wrote a letter to Qian Xuesen, inviting him to become his own student at California Institute of Technology. Qian Xuesen went gladly, and he joined the door of von Carmen. For this proud disciple, Von Carmen devoted his life to study and has been vigorously cultivating.

Later, Qian Xuesen was recommended by his teacher to work in the US Department of Defense and participated in many secret plans. To this end, the first reason why the United States does not allow him to return to China is that he has mastered all kinds of accurate data of American missiles and there is a risk of leakage.

Of course, this reason does not hold water. Later, the Immigration Bureau did not collect all Qian Xuesen's books and notes, nor did it find some relevant information. 1949, the news of the founding of New China reached the United States, and Qian Xuesen and his wife Jiang Ying decided to rush back to the motherland as soon as possible to contribute to the prosperity of the motherland.

After applying for resignation, the United States has not responded, but when Qian Xuesen appeared at the port of returning home, the United States directly intercepted him and imprisoned him for more than ten days. In these days, Qian Xuesen lost 30 pounds, and then the California Institute of Technology, where he once worked, sent him a huge bail of 1.5 million dollars. Qian Xuesen regained his "freedom", but this freedom was also under heavy surveillance.

After hearing the news that Qian Xuesen was imprisoned in China, many efforts were made, but none of them had any effect. At that time, the undersecretary of the US Navy even said that "Qian Xuesen could not be spared even if he was shot, and he could match the strength of five divisions wherever he went".

In order to successfully retrieve Qian Xuesen, China even released 1 1 American ace pilots in advance, but the United States still refused to let them go. Later, Qian Xuesen wrote a letter to his friend, asking him to give it to the China government, hoping that the motherland would help him return to China. With this letter, the United States, which has always refused to admit the fact of monitoring, finally has nothing to say and has to let them go.

In order to prevent things from changing, Qian Xuesen booked a plane ticket first, but because the recent air tickets were sold out, his family had to book a boat ticket, but because the first-class tickets were also sold out, Qian Xuesen of anxious to return had to buy a third-class ticket.

The day before he left the United States, according to the regulations of the Immigration Bureau, he went there once a month to register, which was his last time to ascend the throne. Since then, he no longer has to be monitored by the US Immigration Service. On September 1955, Qian Xuesen and his family set foot on the road of Cleveland President. On the way home, Qian Xuesen received a telegram from his father Qian Junfu, which only said:

Who sent the telegram? It was not until 50 years later that the Ministry of Foreign Affairs declassified some files that the answer was obtained. At that time, the Ministry of Foreign Affairs was worried about Qian Xuesen's safety, fearing that something would happen on his way back to China. In the name of his father, he specifically told him to stay on the boat and not to go ashore.

From 1955 to 10, Qian Xuesen finally returned to the motherland. He always believed that he could go back. Returning to China was an easy task, but it was extremely difficult for Qian Xuesen, but even so, it could not stop his determination to serve the motherland.
