A little background. For most parents, they think that an American education is supremely prestigious and would set up their child(ren) for the future. With that in mind, they will make a lot of personal sacrifices to do this. In the media, we see a lot of affluent Chinese parents buying their little "emperors" Porches and Tibetan Mostiffs. Those are the exception and not the norm. For the vast majority of those who send their kids to America for schooling, they are pretty much putting every single penny of their savings and then some (normally borrowing money from friends and relatives). Likely, these parents have never been outside of mainland China, with the exception of maybe a weekend trip to Hong Kong. All they know of America is what they see on the big screens and the little screens, not exactly a true portrayal of diverse America. Even if money wasn't an issue, it is still relatively difficult for a working age Chinese person to get a U.S. Visa to visit the United States. For whatever reason, there is this misconception that once over here, these people will not go back and then become a burden of the state.

I wouldn't send my child to a school in China without either personally seeing the school myself or speaking to a number of american students that had already gone there.

As stated above, more often than not, it is not possible for them to visit the schools for financial, legal, or bureaucratic reasons. They don't have a Rolodex of the alumni of the schools and call them up. Even if the missionaries were to offer them names and phone numbers, it is more than likely that they will only offer up those who will give praise. Additionally, these parents will be extra careful in not offending these missionaries because they are afraid that they might offend and their child(ren) lose the golden opportunity for an American education so the questions will tend to be more politically correct. Certainly they will ask what the environment is like and what is a normal day for the students, but I am sure they will not be told about the constant (stealing a line from dublinben) and immersive brainwashing.

When you send your kid to a christian school, don't be surprised when they return to you as a christian.

When I buy a bag of sugar from the local store and it is labeled as so, but I find flour inside, I would indeed be very surprised. Mix the language barrier in with the vagaries, half-truths, and outright lies and you have mislabeled products.
