Can the Greek non-profit residence card return to China?

The permanent residence card and Greek non-profit residence visa for Greek immigrants who buy a house are not Greek nationality in legal concept. After obtaining the status, they still belong to ordinary China citizens, and if they live in Greece for a long time, they belong to overseas Chinese. If you want to join the nationality, you need to have certain residence requirements.

Different countries have different immigration policies. Take Greece as an example. Immigrating to Greece only means that you have obtained the local "permanent residency", that is, you can live and live in Greece and enjoy the same benefits as local residents, but you are still a citizen of China and a native of China.
