You're obviously a rich 2nd generation proud idiot who's only ever been in beijing or hong kong. There are whore houses (what do you think the pink light means asshole?) massage parlours, hotels, KTVs hairstylists (6 women in the salon at 11 at night to cut hair? lol) all selling sex everywhere, sometimes even across the street from a police station.

You are a blind, ignorant fool. WAKE THE FUCK UP.

There is prostitution in European countries but there are nowhere near as many whores as there are in china.
