After the July 7th Incident, Hua, a great mathematician, returned to War of Resistance against Japanese Aggression's motherland, which was in full swing, from Britain, where life was comfortable. After returning home, he took an active part in the anti-Japanese national salvation movement, not for money or for a degree.

1950, he became an internationally renowned first-class mathematician and was hired as a tenured professor by the University of Illinois, but he resolutely led his family back to the newly liberated motherland.

Qian Xuesen returned to China to engage in science and technology.

1955 In the early winter, Qian Xuesen, who had just broken through the obstruction of the American authorities and returned to the motherland, visited Harbin Institute of Military Engineering. Dean General Chen Geng asked him: "Can China people engage in missiles?" Qian Xuesen said, "If foreigners can do it, why can't China people do it? Are China people shorter than foreigners? "

This sentence decided Qian Xuesen's career in rocket, missile and space. With his fundamental contribution to China's rocket and missile technology, aerospace technology and even the whole national defense high-tech cause, he has written a brilliant chapter for the modernization of our military weapons and equipment.

3. Feng Ru makes airplanes.

The plane was first developed by the Wright brothers in the United States at the beginning of the 20th century. They didn't expect that only a few years later, China people developed their own plane. This ambitious China man is called Feng Ru. Feng Ru is the son of a peasant family in Guangdong.

12 years old, he wants to go abroad to make a living, but his parents can't let him go. He said: "It is not my wish for a gentleman to stay at home all his life!"

He came to the United States and worked hard to learn all kinds of knowledge and technology such as machinery and electricity. 1904, when he heard that the northeast of the motherland was invaded by China and Russia and the Japanese were slaughtered at will, he was extremely angry.

At that time, the Wright brothers in the United States had just invented the airplane, and Feng Ru thought that if China had an airplane and held the frontier Haikou, foreign countries would not dare to bully it. He said to his friends, "I decided to develop my own plane and fly back to serve my country."

If I don't succeed, I'd rather die. "So he searched for information everywhere, studied hard and started to develop with the money he raised. His parents miss him and hope that he will go back to China to visit relatives. He said, "If the plane breaks down, I will never go back to China. "

1909, Feng Ru successfully built an airplane. He flew his own plane over Oakland, USA, surpassing the Wright brothers' first record. An American newspaper published an article saying that "China people have more aviation technology than westerners".

Feng Ru later returned to China to organize aviation and died in an air show at the age of 29. He made an unforgettable contribution to the revival of China.

Wu is waving the national flag of China.

Wu, an old revolutionary in China, has a strong sense of national pride since he was a child. When he was young, he went to Japan to study in a school. 1904 new year's day, the school hung flags from all over the world to celebrate.

But I didn't fly the national flag of China. Wu was so angry that he took China students to the head of the school to protest: "Why don't you hang the China flag? If the school does not apologize and correct its mistakes, we will go on a hunger strike. "

The school said discontentedly, "We are so kind to you on weekdays, and your family is in financial difficulties. We don't urge you to pay tuition, but we also give you pocket money. Why take the lead against the school? " Wu said seriously, "I am very grateful that the school has been very good to me.

But hanging the national flag is a matter of national honor and disgrace. I can't help but fight to the death! "The school has to admit its mistake. 10 years later, Wu became a revolutionary.

Once he went abroad, he took a Japanese boat, just in time for New Year's Day in 19 14. Ten thousand flags were hung on the boat to celebrate, but China's national flag was still not hung.

Wu remembered what happened 10 years ago, and thought sadly: the motherland is poor and weak, and it is looked down upon by foreigners, and even the national flag can't be hoisted in China! But I'm from China. Can I see the dignity of my motherland being hurt but turn a blind eye?

Therefore, he did not hesitate to lead the China compatriots on board to protest against the captain. Seeing that the people of China are so patriotic and United, the captain quickly apologized.

5. Yuan Longping, the father of hybrid rice.

Rice is the staple food of China people. But for a long time, the rice yield is not high and the population is large, so farmers can't meet the demand of "eating" by farming and planting rice all the year round. Low grain output is a big obstacle to China's economic development.

Yuan Longping, an agricultural scientist, is determined to tackle key problems for the country and solve this problem. Yuan Longping is an agricultural school teacher in a town in Hunan. Despite the poor working conditions, he devoted himself to scientific research. In addition to teaching every day, it is to cultivate high-yield varieties in experimental fields.

In his experiments, he found that natural hybrid rice had large and full ears and high yield, but when it was planted again the next year, it degenerated and lost its advantage. He wants to carry out an experiment to cultivate hybrid rice seeds that can maintain high yield.

For this ideal, Yuan Longping spent a lot of energy, sometimes observing in the experimental field, even ignoring his own home. After 10 years of efforts, it was finally cultivated successfully.

The yield per mu of this hybrid rice is over 65,438+0,000 kg. After the nationwide promotion, the rice production in China increased by 1 000 billion kilograms in a few years, which is really a leap! Yuan Longping won the first National Special Invention Award.

The United States and other countries also introduced his achievements. Known as the "father of hybrid rice", he fought a turnaround to change the backward state of grain production in China.
