Hi folks,
after lurking for a while here, here's the time for sharing a little sport I found, for BBS lovers.
Go to the crossroad of Huangpi nan lu / Jianguo xi lu, and head back by foot a little north on Huangpi lu (it's a one way street so unless you come from north on Huangpi itself, you can't go there by taxi from Jianguo xi lu).
At the crossroad itself, there are quite a few BBS, more or less good quality but in general don't expect FS or even BJ. HJ is all you'll get, but some have really nice girls though, it might worth its 50 kuais.
So, head north on Huangpi lu, you'll pass a BBS that has a kind of door that has been closed (as in, they filled it with bricks and cement). Keep going maybe 20 meters, you'll find another BBS. It's this one I'm talking about.
Here you'll find a variable selection of girls, notably one "Beibei" from Hunan who is about 19, very pretty and gentle. She's bring you to the locked room at the back, where there are 2 separate smaller rooms where you can do your deed. It's dirty, it's dark, well, it's a BBS...
Anyway, Beibei is really nice, does FS for 300, one of those BBS pearls that make BBS worth trying
