"learning native Chinese" in my view is not a sufficient reason to educate a child in China. I am trilingual and in my youth it did allow me to apply for menial jobs in a few countries. fruit-picking and table-waiting etc. For professional and international life, really fluent English, even with a thick scottish accent, is infinitely more important than any number of tribal languages.
Anyhow, google and tencent already have instant universal translators on the way so languages are obsolete and only interesting for historical reasons.
education is a huge scam and a waste of money, the only exception is Hogwarts (my alma-mater). Otherwise, I'd say find the cheapest possible (ie move to europe if possible).
And i almost forgot the reason i began to write in the first place: connecting to an earlier post, i saw a tv reality-show from china where indeed the teachers (default profession in china for anyone who isnt capable of anything) took every opportunity to single out the foreign kid. That child clearly had behavioral issues and probably did not turn out to be a happy camper. He was a ginger, too, poor little fella.
