I canยดt answer all of you questions but i will try with those i can.
1. there is mutiple districts in Shenzhen you can have fun, why Luohu is main is because itยดs near the train station for ppl to go in and out of HK so itยดs more easy(to find customers). i mostly go about in futian but itยดs up to different ppl where they would like to stay and have fun, Good luck !!
2. Depends on which hotel you are staying in, there is some hotel who like to have some class and stops these kinds of things but mostly 3-4 stars hotels would rather earn money so they do allow you to bring girls up to your room after 11 pm. (take for example Hotels in ChangPing the KTVยดs in the same building as the hotels so itยดs just pick the right girl and go up to your hotelroom
)
3. In my experience they differ from KTV to KTV there is cheap ones who charge 1-2-6 and there is expensive ones who charge you 5-10-20. It all depends if you know the manager who arranges your room or the mamasans who handles the girls. (get to know your KTV Thats my motto)
6. Prices are always a hot topic in those places yes Short time for 200 yuan is possible but you can haggle(Mostly in BBS:s) and maybe get one for 150 but for KTV:s there is always a set price for drinking time-short time-All nighter. Best way to confirm prices is always speak to the mamasans and decide the price and the duration for the girls (the one you picked and made up your mind on) services.
7. yes it is, because no matter how "normal" these kind of "jobs" are accepted, it is still illegal to do it and you will get arrested if they caught you. Thatยดs why mostly girls have a mamasan aka manager....
8.no problem and no problem, they still arrest you if they have even the slightest evidence that you are paying for sex and throw you in the "Slammer" and the only way to get out of it is to play the "Stupid foreigner" who dont speak chinese and "buy" you way out of jail.
and thats the Question i know the answers to if anyone know the answers to the rest...GOOD LUCK
