I hate to say this, but you don't know what you are talking about. You are making assumptions that are simply incorrect. You get what you pay for as I said before, and as I've talked to ex-pats here in town, I've found there are a few schools that are better than others. I'm not saying TenWest is the only good school in town, but I'm very clearly saying it is certainly one of the best. I've studied language acquisition — albeit briefly — and I feel that I'm qualified to make an assessment of how Westerners learn best.
If you don't understand why non-native Chinese speakers want to learn 普通话 as opposed to 昆明话, I don't think I'm going to be able to convince you here. I can tell you are a non-native speaker, but I can't tell if you are Chinese or not. Firstly, if you are not Chinese, you seem to really dislike Chinese culture. If so, why live here? If you are Chinese, you sound very bitter. This is not endearing to foreigners. It's hard enough for us to learn a new language and live in a culture that is not our own (and mind you, most of us really like China), but it doesn't help when we see so much negativity.
Lastly, the owner of TenWest has become a friend because he has treated me with respect and honor and because I am learning a language at his school that I never thought I would have the ability to learn: Chinese. He also asks his students for feedback and if there is anything he can do to make their learning experience better. This is truly exceptional in ANY country. This is why it is offensive to me when people speak about things they are ignorant of. Please don't belittle others when you clearly do not have enough information to make such a judgment.
The reason I would come on GoKunming and defend this school is because I think so highly of it, I have become a fan, someone who is willing to talk about a brand simply because their experience has been so positive. That speaks for itself. This is what Apple has. You can't pay for that. You have to provide a service or product at a price that people believe to be lower than what that product or service is actually worth. I believe TenWest does that in spades.
