Under the Rose (1992)

James Wong and his female assistant visited various kinds of pleasure-houses, including invisible dens, high-tech private dens, smuggling blackpoints and famouse tryst places, both large and small ones, throughout Hong Kong. They also looked back to the Scientific Beauty in Lai Chi Kok Amusement Park, striptease in the Kowloon Walled City and the old stories in fish-ball stalls. There are also interviews of call-girls and grooms.

Unfortunately the movie Under the Rose is not yet available on Disney Plus.
