As we all know, if a country wants to develop and become stronger, it must rely on talents. From the perspective of historical experience, countries with abundant talents often develop too poorly. The strength of the United States comes from the United States' military and economic strength, but it also cannot be separated from its powerful talent. But although there are many talents in the United States, not many of them truly belong to the United States. Many of them went to the United States to get a US green card. However, it has to be admitted that the United States still has many methods to retain talents. The United States will use various generous conditions to tempt scientific research talents from various countries and let them stay in the United States to do things for the United States.

Since the last century, many countries have regarded the United States as a slogan, thinking that the United States is strong and that it will definitely have good development if it stays in the United States. Therefore, many capable people will go to the United States to study, but very few people return to China this time. For example, this Chinese once publicly stated that he would not return to China, but would stay in the United States to help the United States build artificial missiles. As soon as these words were spoken, many Chinese people hated it. After the fall of the Qing government, a group of patriots emerged in our country. They were concerned about the motherland and hoped to build a stronger China through their own efforts. In order to better build and serve the motherland, they had to leave their hometowns and go abroad to learn advanced technology and knowledge. After completing his studies, in order to save the country, many scientific research talents set off a wave of returning to China. These two were two brothers from the same school, and agreed to study abroad together and return to China to serve their motherland together. However, four years later, one of them changed his mind. He was greedy for life in the United States and was obsessed with the various conditions offered to him by the United States. Forgot the original promise and completely put aside the belief in serving the motherland. These two are geniuses in the aviation and missile industries respectively. They are Liang Sili and Lin Hua. I believe many people know Liang Sili's name. This person is the son of Liang Qichao . Liang Sili, who inherited his father's will, has secretly made up his mind to serve the motherland since he was a child.

Through hard work, Liang Sili has become a top expert in the field of rocket control systems in my country, and his doctors are all contributing to the national defense cause. However, his fellow disciple Lin Hua was once full of ambitions, but after arriving in the United States, he was influenced by the culture and thoughts there and changed his original intention and even started to help the United States build missiles. Lin Hua became famous after helping the United States build the Militia-3 missile. As the new generation of intercontinental missiles in the United States, the Militia-3 is one of the most deterrent weapons to me. Many people would not have imagined that this missile was actually made by the Chinese. In order to make missiles for the United States, Lin Hua actually gave up his nationality, gave up the opportunity to be a Chinese, and joined the American nationality. Such a person is really annoying.
