As far as I know, the raid campaign of such things is still going on. We cannot see an end before our Lunar New Year (in next February). Therefore if you visit Beijing, the first and most important issue is to accommodate in a girl-friendly hotel. Several years of experience tells me Hotel Kunlun is the best choice. Its security guard will not stop any escort girl even she visits hotel in midnight. Also its elevator is accessible without a room key. Many other good hotels need you to come to lobby to pick up the girl, or need a registration of the girl visiting ur hotel or even reject her visit after 11pm.
If you stay in a unfriendly four-star or three-star hotel, do keep an eye on the waitors or waitress. They are watching your activity. So do choose a good hotel to avoid any trouble.
In such a particular season, a wise man will not take any risk cos he has a good job and family. The secure way is to contact a creditable agency to call a top escort girl to your hotel rather than to visit a massage parlor or sauna, which is dangerous right now.

I do not suggest you to consider any "independent girl" cos 99% of them do have a boss and you cannot trace her in case there is any dispute during the process of service.
