Buying BYD shares?

[2Btoo]

Guys,

I have a bit of spare cash at the end of the tax year and am looking for something unusual to invest in. While pondering this matter, my mind lit upon BYD; that Chinese company that seems to be making dirt-cheap 'leccy cars and which may have a big and bright future. Reasons not to buy are several; not least that The Omaha Sage has significantly trimmed his position although not exited altogether.

But this leads on to the how? How does one buy shares in this company? I can see the tracker on Google Finance (https://www.google.com/finance/quote/002594:SHE?window=1Y) and I can see the markets it's traded in but how do I access those markets?

Thanks!
