Sorry, I can not type Chinese in my computer. I face the same problem as
yours, takes me a lot of time to think how my parents could live in
American happily.
Conclusions:
If they can not basically understand English, they should go back to china.
Language barrier is huge problem they will face when they are older and
older, without communication skill, they are totally dependent on their
children, they live like blind, dumb people, too much burden and suffer on
children and their parents. People are social animals, they want to
communicate.
