What does the term “red light district” mean or what does it refer to……?
A red-light district is a neighborhood where prostitution businesses flourish, so named for the practice of placing a red light in the window to indicate to customers the nature of the business. Some say the origin of the red light comes from the red lanterns carried by railway workers, which were left outside brothels when the workers entered, so that they could be quickly located for any needed train movement. [1] One of the many terms used for a red-light district in Japanese is akasen (赤線), literally meaning “red-line”, apparently of independent origins from the English term. In different cultures red-light districts are identified differently, the most common being “district of prostitutes” (i.e. in Hindi – Randi Guli or Street of Prostitutes; in Bengali – Khanki Para or Neighbourhood of Prostitutes http://en.wikipedia.
