Buying htc desire s in china?

One of my friends is going to Guangzhou in China recently. I want him to buy a HTC Desire S phone for me as this is not available in my country Bangladesh. The problem is, both me and my friend do not know if it is available in Guangzhou. I guess it is available; but do not know where to buy. Does HTC has a showroom in Guangzhou? Or any other suitable place? I think people live there and know well can tell me. and also if possible, please mention the price. thanks in advance.
