GKs "Mandarin Schools" listings is quite out of date, It only seem to contain valid websites/contact info for these (private) schools:
* Kunming College of Eastern Language
www.learnchineseinkunming.com/
* Huayang Academy
learnchineseinyunnan.com
* Tenwest Mandarin
www.tenwest.cn
* Keats
keatschinese.com/
Does anyone know of any other private schools (that are able to provide study visas)?
