As far as my experience it's only in Shanghai and i don't see the big deal with the red rope acrobatic sex stuff, it's great the first time you see the red ropes and watch the girls strap herself on it and swing around, she blows you on the red rope and you bang her on it, no big deal to me. Been there done that. Have you been to the red rope place yet? It's at the Shanghai Hotel and the XiangMiHU Hotel on Wu Zhong road.
