In China, the pooning and massage scene is more discreet and underground.
As mentioned, be prepared to shell out big coin for bribes and such. When I was there, couldn't see much in terms of SW, but there are a lot of hotties, especially around the main shopping areas.
There may be some SP advertising in the newspapers, but again, it is pretty discreet and you need to speak the language. MP wise - lots of MP, but likely they will upcharge you lots if they know you are a foreigner. And even I couldn't tell if there were extras or not.
I did try one from the massage saloon in my 4 star hotel. Most higher rated hotels have they own saloon within the buidling. There was massage + extras and even FS (and I came across a cute Russian girl that worked there, but she didn't do FS). The downside is that the prices came out to almost the same cost as here in Canada (at least for me). So I passed on FS and the R&T was pretty ok.
So play it safe and discreet, check out your hotel saloon first and try to find a MP advertising in English from the local papers. But again - be prepared to shell out $$$.
And again yes - be very careful of pickpockets and scams. Some stories I have heard is that hot girls ask you to buy them a drink and next thing you know, you have a bar tab of over $500 RMB!
And I got some cash pickpocketed out of me too - very professionally done.
