Is it troublesome to return to China after immigrating to Australia?

Does this immigrant mean green card or naturalization?

If it's a green card, and you still have a China passport, you can go back to China at any time, or you can live in China at will, because you are still from China.

If you have become an Australian citizen, Australia will issue you a passport, that is, you hold an Australian passport. Since China does not recognize multi-national citizenship, if you want to live in China for a long time, you need to apply for a green card in China. But at present, there are very few qualified people, most of whom are professionals in a certain field.

Of course, if you give up your Australian citizenship, you can still restore your China citizenship and get a new China passport.
