Does Hanoi have a red-light district?

Prostitution is a widespread phenomenon in Vietnam, and cities such as Hanoi, Haiphong, and Ho Chi Minh City have red light districts of differing degrees. In these areas, laws and morals are ignored, and sex is sold freely. As soon as darkness asserts itself, glamorous girls will tend to walk along streets in and around shaded areas to "wait by the trees for rabbits." To the locals, these ladies are better known as "night butterflies."
