The most visible public venues for sex workers in Hong Kong, especially for tourists, are massage parlours and the so-called "Japanese style Host and hostess clubs".However, most of the commercial sex worker industry consists of women working in small, usually one room apartments, usually referred to as "one-woman brothels", the equivalent of the "walk-up brothel" in the United Kingdom.There are girls from all over the world working as escorts because of the good markets for locals and tourists.
There are also "underground" organizations (such as Thai restaurants and escort bars) that arrange for foreign (usually Thai) and mainland girls to gain work in Hong Kong legally with an entertainment visa, but in fact they actually work in go-go bars in Wan Chai or other hostess clubs around Hong Kong.
In the Philippines, "agencies" officially recruiting girls as bar maids operate quite openly and professionally, one such agency can for example be found in Mabalacat, near Angeles City.
Many work on a freelance basis in Wan Chai bars and discothèques.
Many migrant sex workers arrive on a short tourist visa and try to make as much as money as possible by prostituting illegally before leaving Hong Kong, some returning frequently.
Most of the hookers went to the island from the mainland provinces of Hunana, Hubei, Sichuana nd Fujian.
