The United States has completely stopped immigration.

Many countries in the world began to revive after the industrial revolution and gradually moved towards a better development path, and the first country to benefit from the industrial revolution was Britain. After the first industrial revolution, industrialization began to replace labor, and then the steam engine was invented. Britain was also the first country to establish a constitutional monarchy, and later became a big country with colonies all over the world, but this hegemony was replaced by its former colony, the United States.

Because the United States made a fortune in two world wars, accumulated capital rapidly through wars, and its strength quickly surpassed that of other powers. After the disintegration of the Soviet Union, a brand-new world pattern was re-established and a superpower situation led by the United States was formed. Then, in order to introduce talents, the United States also introduced regulations on the introduction of foreign population, providing extremely high treatment to those rich people or researchers who immigrated to the United States. Many people moved to America to work and live. One of them made nuclear weapons for the United States in order to obtain permanent American citizenship, and now he wants to return to China to retire. Then who the hell is he?

The rapid end of World War II had much to do with Germany's defeat, but the two atomic bombs dropped by the United States in Japan also showed some effect. The tragic situation in Hiroshima and Nagasaki made Japan lose its ship and had to declare the imperial edict of unconditional surrender. Then World War II stopped completely, and the people of the world ushered in a relatively stable and peaceful situation. China experienced War of Resistance against Japanese Aggression and the War of Liberation, and New China was founded, but the country in this period was still in its infancy, and all aspects were not perfect and developed enough. Therefore, during this period, many students chose to study abroad for broader knowledge. In fact, during World War II, many students have gone abroad to study. With their own efforts and talents, they have made achievements in many aspects.

Therefore, after the founding of New China, these students who have made achievements abroad and obtained honorary status have chosen to return to China to work hard for the development and construction of the motherland. They want to do their part to revitalize the national cause. Even though they are well paid abroad, some of them choose to return to China to create. However, some people find it difficult to give up their high-paying status and reputation, so they leave their own nationality and choose to join another country's nationality. This is the case with this international student. He chose to stay in the United States to make nuclear weapons for him in order to obtain permanent American citizenship. When he is old, he begins to miss his motherland, so he hopes to retire in China.

His name is Ye Lin. He is a researcher who has made great achievements in military weapons. He and Liang are classmates and studied in America together. Although they became good friends in America, the road after that was completely different. Liang Xuecheng returned to China and led the team to contribute to the motherland. Later, he developed Dongfeng series missiles and became a hero admired by everyone.

But it is very different from the beam. He can't let go of everything in America, whether it's wealth or status and reputation, it seems more important in his heart. Therefore, Ye Lin chose to stay and strive to obtain American citizenship, and developed a series of militia missiles. This kind of missile is no less than nuclear weapons, and he successfully obtained the American green card with this achievement. Later, Ye Lin became the chief scientist of Boeing Company and was received by the President of the United States. As an immigrant population, it is remarkable for outsiders that he can enjoy such an honor in the United States.

Beam is not like this at all. Although the domestic conditions were insufficient and the equipment was incomplete at that time, he led the people to overcome many difficulties. Even the food is just ordinary rice and vegetables, and life is very poor. But under such conditions, he developed Dongfeng series missiles. Facing the coming of the east wind, Liang said happily that his classmates stayed in the United States and also developed militia missiles aimed at China, but his east wind was as good as his, and he was a unique national. Now that Ye Lin is over eighty years old, he suddenly thinks of his motherland and hopes to return to China to support the elderly.
