According to the Hong Kong law (cap 200, section 117), premises, vessel or place are or is used wholly or mainly by 2 or more persons for the purposes of prostitution treated as a vice establishment for the purposes of prostitution, and anyone who runs, hires or rents such places could be prosecuted. To escape the restrict of this law, the only-one-prostitute apartment "yeit lao yeit fong" was developed. The famous Hong Kong film "Golden Chicken" (金鸡) is a story about such a woman.
