Serious mandarin schools in Hong Kong

If you want to learn Mandarin Chinese, I suggest trying your luck over the boarder in Mainland China, or else go to Taiwan,
since most Hong Kong people either
1) don't like speaking it
2) don't know how to; you won't get a chance really to speak
Mandarin here in HK
3) alot of HK'ers look down on Mainland Chinese, and the Mandarin dialect itself
(some regarding it as just a 'redneck' language).

I learnt my Mandarin in Taiwan, and have met other foreigners who have learnt it previously in Mainland China, and they told me Taiwan's Mandarin is more clearer than Mainland Mandarin.

Think of it like this;
you go to Beijing and learn Mandarin Chinese, you will get Mandarin with a Beijing accent (very difficult to understand). Last time I spoke to someone in BJ, I hardly knew what he was saying. Not to mention, Mainland has over 50 ethnic minorites, and a hell of a lot of different accents and dialects.

But with Taiwan, they only speak Mandarin, Taiwanese, and Hakka only. And people from the south and north pretty much sound the same; Taiwan is a pretty tiny place.

Just my 2 cents.
