Thanks HH for the weblink - have already been put on to Wechat by a chinese friend. From some initial research looks like there are plenty of options in Dalian which is reputed to have the most beautiful women in china. I am planning to be there for a year or two so will try and check out some of the following:

dance halls
saunas/bath houses
karaoke bars (KTVs)
barbershops
escorts

and there is always the good old option of trying to pick up at one of the bars that the more adventurous local women frequent - I hear the Shangrila is a good place to start

will keep you posted
