in Beijing, often there is a mamasan hanging around outside the hotel who will approach you regarding a girl
she will then call the girl and in 5 min someone shows up, she can call others if that one is not to your liking
the girl will go with you to your room, don't eat or drink anything she might spike
I have found this is quite a good option, these are girls making some money on the side with the help of the mamasan, not the organized ones in the side street whorehouses the cab drivers will try and talk you into seeing (cab drivers hanging outside of some of the pickup bars for instance)
some hotels have close by or in the downstairs, a steam room massage venue. legit massage with extras normally, but the doors either have windows are have the door locks, door knobs removed
girls do hand job covered up by the towel so no one can see who might be walking by
prices similar to here, might be a bit lower
