I know many Chinese that manage to live in America with minimal knowledge of English. There are many sizeable Chinatowns and "bubble" communities in America where a Chinese/Taiwanese person could immerse himself/herself in and never really have to deal with English.
How do these people get visas?
they have relatives in the usa.
Or EB5. If you have $500k you can buy in. Apparently about 99% of the 10k issued each year go to Chinese.
Or move to Taiwan if you have the chance.
Taiwan is lovely but still suffers from air pollution. Much of it is local pollution, but some also that drifts over from China. I found it quite challenging when I was there.
But the food is great, so there's that.
That same pollution drifts over South Korea as well.
