In August 1935, 24-year-old Qian Xuesen rushed to the United States from Shanghai. Feng, one of the great scientists. Carmen has lived in the United States for 20 years. During these 20 years, his career has advanced by leaps and bounds and he has made brilliant academic achievements. But during these 20 years, he missed his motherland all the time. He returned to China in 1955 and created great progress for China with "two bombs and one satellite".

After reading this article "Qian Xuesen's Patriotic Story", I found that my tears were falling drop by drop. It can be described as tears like rain. Yes, Qian Xuesen's patriotic spirit is worth learning from. Moreover, when Qian Xuesen was imprisoned on the island again, despite endless torture, his desire to return to China did not waver or change at all. With the help of his wife, he wrote the letter on cigarette paper and sent the letter to Zhou Enlai to break it. The lies of the US government. It arrived in Hong Kong on October 1, 1955, and was called the "Father of Missiles" after it set a good pioneering example for China with two bombs and one satellite.

There are many patriotic people like Qian Xuesen. I will definitely read more of their patriotic stories, constantly enrich myself, push myself, work hard, come on! Qian Xuesen's Main Deeds and Contributions Chapter 2

In 1947, the 36-year-old Chinese scientist Qian Xuesen was hired as a tenured professor at the Massachusetts Institute of Technology in the United States. 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 aerospace science in the United States, and one of the five members of the Caltech Rocket Research Group, the earliest rocket research organization in the United States. The "Karman-Money formula" developed by him and von Karman is still widely used in aviation technology research.

When Qian Xuesen learned the news of the founding of the People's Republic of China, he was immediately immersed in great joy. He has lived in the United States for more than 10 years and 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! Qian Xuesen's decision to return to China caused panic in the United States. Qian Xuesen's plan to return to China was blocked. His books and notebooks were confiscated. He was also arrested and imprisoned in an island detention center, where he was subjected to endless torture.

In the California Institute of Technology, due to his insistence on justice and strong protests from students, the U.S. secret service was forced to release him. During the days when he was striving to return to the country, Qian Xuesen was more concerned about the construction of the motherland and often "Overseas Chinese Daily" and other newspapers learned about the situation in New China. 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 received great concern from China.

In August 1955, this diplomatic struggle finally won, and the US government was forced to agree to Qian Xuesen's return to China. Qian Xuesen broke through the obstacles of rebirth and returned to China, immersing himself in the research of military science. He has continuously launched scientific research results and made great contributions to the motherland. He is known as the "Father of Missiles". The State Council awarded him the honorable title of "National Model Worker". Settling in the United States and being hired as a tenured professor is the dream of many people. However, Qian Xuesen gave up everything for the prosperity of the motherland. Today, many people have lost their ideals and lost their direction because of money. Qian Xuesen's patriotic words and deeds undoubtedly encourage us to study hard and grow up to serve the motherland.

Qian Xuesen's Main Deeds and Contributions Chapter 3

Today, I accidentally saw Qian Xuesen's story in "Science" and realized that he was not only a rocket expert, but also very patriotic!

He graduated from Shanghai Jiao Tong University in 1934. In order to better serve the motherland, he went to the Massachusetts Institute of Technology for further study. In 1936, he transferred to the California Institute of Technology to continue his studies. He took the aerospace scientist von Kármán as his teacher and studied aeronautical engineering theory. Qian Xuesen studied very hard and obtained his doctorate three years later and stayed at the school to teach. After the founding of New China in 1949, Qian Xuesen wanted to return to China to serve the motherland, but the United States did not allow him to return. U.S. Navy Undersecretary Jim Boots said that Qian Xuesen was equivalent to the strength of five divisions, and even if he was shot, he would not be allowed to return to China. But later, after all the hardships, Qian Xuesen finally returned to the embrace of the motherland and made a huge contribution to the research and development of our country's "two bombs and one satellite".

After reading this story, I couldn’t help but think of many people like Qian Xuesen who love the motherland. Some of them donate their money to the country for construction, and some use their knowledge to develop the country. Some even sacrificed their precious lives for the benefit of the country. National Day is coming soon, and I can’t help but ask myself, how should we love our motherland? I think as a student, we must first learn the textbooks well and lay a good foundation so that we can serve the motherland well in the future.

When we encounter difficulties, let us think of people like Qian Xuesen who love the motherland. Is there anything else that cannot be overcome? Qian Xuesen's Main Deeds and Contributions Chapter 4

On October 1, 1949, the People's Republic of China was established. Qian Xuesen knew the good news and wanted to return to the country immediately. He was willing to give up the generous treatment abroad and return to the motherland. At that time, U.S. Navy Undersecretary Kim Hill said: "No matter where he goes, Qian Xuesen has a strength lower than five divisions. I would rather kill him in the United States than let him leave." After reading this, I think everyone is angry. My heart was pounding and my teeth were clenching. It was so disgusting!

"I am Chinese, and I want to serve the motherland." In the end, Qian Xuesen finally overcame many difficulties and threw himself into the embrace of the motherland, breathing with the people, sharing the same hardships, and being blessed. We share the same hardships and only want to serve our most beloved motherland.

Then, "my country's first artificial satellite flew into the sky, and the first interstate missile was successfully launched." Qian Xuesen devoted a lot of effort. Since Qian Xuesen returned to serve in China, the launch of China's missiles and atomic bombs has moved forward at least 20 years. Known as the "Father of China's Missiles" and "The King of Missiles".

"I am Chinese, and I want to serve the motherland." I thought: Grandpa Qian Xuesen's simple and ordinary words made us all feel a great sense of pride from the bottom of our hearts after reading this story. Love for the motherland and admiration for Grandpa Qian Xuesen. Of course, as the new generation of Chinese teenagers, we must study harder and serve the motherland like Grandpa Qian Xuesen when we grow up, and build a better future for our motherland!

No matter what kind of person you are, you must be sentimental about the motherland in your heart. In your heart, you must first think about serving the motherland and loving the motherland. Qian Xuesen's Main Deeds and Contributions Chapter 5

Qian Xuesen transferred to the California Institute of Technology in 1936 to continue his studies, and became a student of the famous aeronautical scientist von Kármán.

Soon after, upon the recommendation of von Kármán, Qian Xuesen became the youngest tenured professor at Caltech. In the 15 years from 1935 to 1950, Qian Xuesen made great academic achievements and enjoyed generous treatment in life, but he always missed his motherland. However, Qian Xuesen's return to China was full of twists and turns. At that time, it was not easy for Chinese scientists in the United States to return home, and Qian Xuesen's expertise was directly related to national defense. An American colonel said, "No matter where Qian Xuesen goes, he is worth a division. He must never be allowed to go back." September 1950 In the middle of the month, Qian Xuesen went through the procedures for returning to China. He bought a plane ticket from Canada to Hong Kong and handed his luggage to the moving company for shipment. However, just two days before he planned to leave Los Angeles, he suddenly received a notice from the U.S. Immigration and Naturalization Service - he was not allowed to return to the country! The Immigration Bureau threatened that if you leave the country without permission, you will be fined or even jailed if you are caught! The Immigration and Naturalization Service’s persecution of Qian Xuesen aroused public outrage in the American scientific community. Many friendly people in the United States came forward to rescue Qian Xuesen and find him a defense lawyer.

They raised 15,000 US dollars as a deposit to release Qian Xuesen from the detention center. In June 1955, finally with Zhou's care, Qian Xuesen and his family returned to their motherland after 20 years of absence.

This reminds me of a TV show where many people go to any lengths to get a green card and stay abroad, even going bankrupt. I don’t know how good foreign countries are, but I know that a person like Qian Xuesen is someone that every country will open its door to welcome. I hope I become such a person.

In the past few days, I have read Qian Xuesen's story. Qian Xuesen is a famous scientist in my country. He studied in the United States when he was young. After hard work, he became a world-famous scientist in the aerospace industry. Americans praised him as "a bright star in the galaxy of scientists." Although the United States gave Qian Xuesen a high honor, he had one wish: "I am Chinese, and I want to serve the motherland." When New China was founded in 1949, Qian Xuesen decided to return to China immediately after learning about it. The United States wanted to keep Qian Xuesen, but it did not shake his mind to return to China. After several years of hard work, Qian Xuesen finally returned to the embrace of his motherland. After returning to China, he led the Chinese people to usher in the dawn of the space era.

After reading the story of Grandpa Qian Xuesen. I think Grandpa Qian Xuesen is great, because Grandpa Qian Xuesen always thinks about the motherland and has a heart to serve the motherland. I am also Chinese. Whenever the national flag is raised, whenever the national anthem is played, whenever our athletes win gold medals at the Olympics, when our country's "Shenzhou 6" flies into space... I will be there for me. It is the Chinese who are moved and proud. I want to be like Grandpa Qian Xuesen and have a heart that always thinks about the motherland.

From now on, I will study hard and be a good child in the class who has the class in his heart, his classmates in his heart, and his parents in his heart.
