Why did China Nobel Prize winners emigrate in the first place?

1. Some scientists originally went to the United States to study abroad, but stayed in the United States because of their superior capital, equipment and scientific and technological strength.

Other scientists stay in America because of their teachers and colleagues.

3. Others, born in the United States, have never been to China before they became famous, and some of them can't speak Chinese, so they can be said to be out-and-out Americans. They were born in the United States for generations, but their ancestors came from China. They have feelings for China, but they consider themselves Americans.

P.S. America is an immigrant country, and many successful people are immigrants. In fact, there is nothing special about immigrants from China.

The United States has strong scientific and technological strength. If those scientists hadn't stayed in America, they wouldn't have won the Nobel Prize. (For example, Deng Jiaxian, a good friend of Yang Zhenning)
