Singapore seems a smart choice. Seems like a great city from everyone I’ve met from there. The general English proficiency is excellent as well.

Whatever you do, avoid Europe. The anti-Asian racism in most of Europe is far more grave than it is in the Americas. and Australia, ok, you’ll have more Chinese community, but it’s probably the biggest cesspool of anti-Asian racism on the planet

You might also look into what Chinese populations are in South America. you might like it there.
