As someone who's recently made the move to China (Hong Kong, and not teaching English), I can say it's a great way for native English speakers to jump start their careers and get responsibilities much faster than at home.
Hong Kong is a bit easier getting used to due to a free internet, less pollution, and stricter food safety laws. But I guess there are more opportunities on the mainland.
