The literal translation of the title of this film is: Capturing Spirit Luring Empress.
The film is based on the true story and even the name reflects it: Spirit Luring Empress is the actual name used by the female leader of the porno ring.
However, there is something willfully left out in this film, which is the reason why those girls turned to the prostitution: the northeastern part of China is where the heavy industry concentrated, the place suffered heavily due to the inefficient and ineffective managerial practice by the government. As a result, workers lost their jobs and eventually, their unemployment benefit had do what they did to survive. This reason is something the film crew dared not to touch and the film is thus incomplete.
