Never trust those business card for massage service in Beijing! They are all cheating people!
Steps:
1. when the girl arrive in your room, they will ask for money first (200-300, or even 700-800)
2. then she will find an excuse to go "downstair" to get something from the boss, ask you to wait for a second
3. of course, she will disappear and when you dial the number, nobody will answer
4. for most of the HK customer, they will just keep silence and treat it as a bad luck only
5. if you really call the police or try to do something to arrest them, the girl will defense herself that she was providing pure massage service and you try to rape her and put you in trouble.
