I experienced similar behaviour in China, people starring and teasing, but mostly that's because of me being blond. For the Gothic scene, there are some in Beijing, Shanghai and Hong Kong, but sure not as many as in Europe or the US. And mostly it's metal or rock. For some good links/news on bands, gigs a.s.o. in Beijing visit
www.rockinchina.com. Does anyone have any suggestions on good clubs or gothic webpages in Hong Kong?
