Disclaimer: I know a bunch of people -- friends, colleagues, neighbours etc that are Chinese/or of Chinese descent.
1. - they got here somehow -- was it hard?. No. They did not have to escape on a raft like Cuban exiles. They just left and noone bothered them.
2. - They seem to be communicating with their families in China with no issues. You know, SMS, email etc
3. - They also travel back and forth, this includes kids, parents, grandmas and grandpas.
Overall, the funny thing is that I never heard any of my friends/colleagues complain about China.
Meantime, CNN and Fox etc keep saying that China is like devil, except worse.
Guess who I trust.

One of these searches is incredibly damaging to Chinese interests, one to US interests.
Try doing them in each country.
At the same time I agree very strongly that China is nothing like the former USSR, let alone the current North Korea.
Ask your friends if they would feel safe to go and openly/publicly criticize the communist party of China and hear their answers.
It only takes them to go and acknowledge membership to Falun Gong/Falun Dafa for them to be put into a organ donor list (while still alive).
