How are overseas Chinese and the motherland closely linked?

Under normal circumstances, when there is a widespread threat, the motherland will provide humanitarian assistance to overseas Chinese, and in very serious cases, it may organize the evacuation of overseas Chinese.

But you must realize one thing, that is nationality. China does not recognize dual citizenship. Therefore, overseas Chinese are called immigrants at best, but at worst they turn their backs on their motherland and become citizens of other countries. What is your nationality? If you need anything, go to your country. It's like I'm an ordinary citizen of China now, and I can't go to the US government for any function. Even if I know, who cares about me? Therefore, naturalization as a foreign nationality is a foreign legal citizen. Don't talk to me about "close contact with the motherland". Even if there is close contact with the motherland, it is often because of two reasons. The first is that you have emigrated and your relatives and friends are still in China. The second is the professional demand, that is, making money at home.

So your formulation of this question is not very accurate. It should be said how the motherland is closely linked with overseas Chinese. Overseas Chinese have voluntarily given up China International. What about their close ties with the motherland? It's like a person who voluntarily abandons his family and divorces, and then shouts to get closer to his ex.
