“Americans” came to China to recognize their ancestors, but were rejected by China. What happened?

Those who originally retained Chinese nationality were naturally Chinese and had the right to return to the country. However, the other group of people who had already had their Chinese nationality canceled were decisively rejected.

Now these people are almost the same as the refugees waiting for assistance at the border of my country. If they cannot get a green card in the United States, they will not receive subsidies, and they will be refused to return to China. Some people are so anxious that they will not give up until they return to China!
