New to this forum

Hey guys, I am new to this forum, being an asian that doesn't understand any chinese I am trying to find out more about the places that cater asian girls to the asian guys. I keep on hearing about sandhurst and bamhurst and someone called Karrie. Is karrie a provider or an agency? Are they reliable for younger 18-19 year old girls and if so, do they have pictures, reviews or a number that I can find? thanks a lot.
